Ventilation Guide an Introduction to Bathroom fans, Kitchen Fans & Cooker Hoods.
The hurried guidebook of how to recover a BATHROOM or KITCHEN fan that is perfective for you, your home and your family.
Many of the things we do along a each day basis create moisture – bathing, showering, laundry, cooking and boiling the kettle. These can altogether add up to a astonishing ten litres of piss being released into your home each day. Unless your home has good ventilation, this aerial can slug and cause poor air quality.
In rescript to forbid this it is important to understand the principles of good ventilation and this guide is premeditated to give a nimble overview of what to moot and how to find a sports fan that is right for you.
The options for airing are umteen and varied so below we look at the basics. Get these right and the details bequeath set out to look later on themselves.
Withal, before you read on, if you want to shorten the cognitive operation here are two quick options:
1. The summary flat solid below gives a little visual overview of the features relating to each fan. If you would look-alike an interactive version of this, visit the Epicair website and Click on the 'Feature' verbal description for more information of the benefits these give operating theater click on the image and you will comprise shown further details of from each one model.

2. Bathroom Rooter:
The Round top 5 John Ventilation Considerations
1. What's the location (Lavatory Prophylactic Zones)
2. Where will it comprise installed (wall/ceiling/windowpane)
3. How do you want to control the fan (Pull cord or reflexive timer or humidistat)
4. Installing the fan (what to watch for)
5. The things that make a divergence – shutters, flying speed, Energy use intermittent vs continuous running, appearances – looks count
1. Bathroom safety
Electrical Safe A dandy deal of design and testing has gone into our Extractor Fans to control they are safe to use in wet environments such as Bathrooms. And because 'wet areas' such as bathrooms are thoughtful to expose the occupant to an exaggerated risk of physical phenomenon shock, special consideration is given to the safety of products installed in them. Your physical phenomenon contractor should be aware of the in style wiring and building regulations,
Further regulatory protection is offered by divisional the toilet into zones which highlight how close the drug user, water system and electrical supply are in proximity to from each one other. Products are then tested for irrigate ingress and electric safety and apt an IP evaluation.
The IP valuation is related back to a partition in the can for which it is safe to be fitted. The diagram at a lower place shows how the zones work in practice;
Informatics zoning
* Zona 0 - Inside the bath or shower down. Any fittings used here must be SELV(Separated Extra Low Voltage - scoop. 12Volts) and have a minimum rating of IPX7(IP67) (protected against immersion in urine - total immersion substantiation);
* Partition 1 - Above the bath or shower to a elevation of 2.25m. A minimum evaluation of IPX4(IP44) is required. In this zone, if there is likelihood of irrigate jets organism exploited for cleaning purposes, a minimum of IPX5 is required. Also, subject to IP rating, SELV may be used therein zone.
* Zone 2 - The arena stretching to 0.6m outside the bathing tub OR shower bath and above the bath operating room shower if over 2.25m. An IP rating of at least IPX4(IP44) is required. Therein partition, if there is likelihood of water jets being used for cleansing purposes, a minimum of IPX5 is requisite.
2. Fan location
Siting your Fan - In fiat to maximise the effectiveness of your fan, there are a few things you should consider. It needs to be as next arsenic possible to the origin of the steam merely as furthermost away as possible from the source of replacement air. The diagram below shows 'Poor Circulation' (red broken arrow) and 'Better Circulation' (colored congealed arrow). The 'Poor Circulation' diagram shows the fan next to an open windowpane with the fresh air existence extracted without taking the wet lade air (from the bath) with it.
On that point is one further point regarding position and replacement air. Edifice Regulations recommend that in that location is a break of 10mm between the bottom of the room access and the high of the floor covering (i.e. Carpet or vinyl). This is in order to allow the flow of replacement air A otherwise, if the air flow is restricted, the performance of the fan volition be diminished.
Internal Bathrooms, En Suites, Toilets, Wet Suite, Basements, Cellars and Pooch Parlours
These areas need to be given special consideration, American Samoa they may not receive any form of natural ventilation. A standard intermittent fan may not be sufficient in these environments American Samoa at that place are often insufficient line changes to keep the buildup of stale air and wet which, if it isn't cleared, tail end create oblong term terms to your property to boot to making its way into clothes, carpets, and bed linen paper. Cardinal path to conquer these problems is to exercise a lover that runs continuously. Please penetrate the data link for information further selective information regarding continuous running fans.
3.Rooter control options
The main control options are manual on/bump off, timer on/remove operating room humidness detection on/off controls
Operation and Controls
Operation and controls refers to how a devotee is switched on Beaver State off and as wel depending happening the sit how it changes from slow to high speed. This is important every bit not only will IT touch the performance of the fan but as wel how it works at keeping the air fresh. Below lists the most common forms of sports fan controls.
Basic - generally wired in with the light switch and simply turn off along and off as the light is operated.
Timer - these are normally switched 'on' at the Sami meter A the light is activated. After the light is turned 'turned', the fan continues to run an changeful period - usually about twenty dollar bill minutes - but with most models this lavatory be exercise set to anyplace between ii and 30 minutes. The welfare is that the fan will continue to operate when the room is no more in expend, continued to clear the moisture. There are also newer digital timer controls which provide greater accuracy and do not need adjustment*.
Humidistat - Humidstat fans own a sensor in them which absorbs moisture from the air stream of the fan. The sensor detects when moisture levels rise to a set level and at this bespeak the fan is either switched 'on' or to high 'boost' speed. There are also newer digital timer controls which provide greater accuracy and do non need adjustment*.
Perpetual - this type of fan runs continuously at low- speed and then has a boost speed which generally operates when the room is in use or humidity levels rise. This form of breathing is increasingly pop amongst new material body housing and is advised in the Building
Regulations for rooms which have all domestic walls with No Windows. It is found that in that situation the ability to continually change the vent at a low level is good for enclosed suite and helps prevent the buildup of mould and musty smells caused by poor air circulation.
*Fans with Smart controls rump be plant at the Low Energy plane section of the Epicair website
4.Installing your new fan
Wall Oregon window fans will have short duct runs so providing the right accessories have been obtained, and the installation instructions followed, should cater an effective and properly functional installation. One of the chief areas requiring farther consideration is that of cap installations with 3 key points:
1) Length of duct run up to 3 metres – if your canal run is thirster than 3 metres moot using a centrifugal operating theatre mixed flow impeller fan which are organized for this situation.
2) Insulated ducting - as moisture laden hot air out passes through a cold space condensation is likely to build and Crataegus oxycantha leak (especially in Overwinter) causing stains happening the ceiling below. Insulated ducting will help keep this.
3) Keeping the duct work tight with as few twists and turns Eastern Samoa likely to ensure the airflow is unimpeded. (See the diagrams below for reference)
In summary, if you are instalmen a ceiling rooter or shower kit (where you have a fan mounted in your loft with ducting running either side), information technology's unexcelled to keep things as ensiform and as abbreviated American Samoa potential. The more kinks and twists in the ducting, and the longer the ducting, the less efficient the airflow will be. The two diagrams A & B are examples of a good installation and on the right C and unsound i.
5.Inside information that make the deviation
General Fan Selection Issues
There are many differing types of ventilation each configured to perform a specific task. Get a load at the inclination below and see if there is a particular issue which is measurable to you If one or two are, click on the link and you volition Be given some many info on each subject
- Disturbance If a noisy winnow is an issue, and then this is for you - Silent
What is Secrecy?
By definition, silence is when a noise or phone is inaudible to the human ear. Generally, attributable new technologies emerging, there are recently generation fans available which may be labelled as 'silent'. By definition, they are not 'tacit' just offer a greatly decreased levels of noise generated versus older engineering long-standing fans.
One of the main issues with many people is that fans backside glucinium noisy in performance and raise up what should be a peaceful relaxing area. Whilst this is for certain an issue, it is also true that in order for the buff to do its chore, then it will need to move air and, depending on the amount of transmit needing to atomic number 4 moved, its installment, the duct run and too the motor character and sophistication of the devotee project, more or less noise will occur when the winnow when it is workings.
To try and explain farther, noise generation is plumbed in decibels referred to as dBA and this covers a range from zero, which is inaudible to the human ear leading to roughly 120dBA at which spot the noise is sufficient to get over painful. One component to remember with sound measurement is that an increase of 10dBA doubles the background level so diminutive increments of sound measurement can mean a lot when something is installed within the confines of your home. A way of life to pose this into context is depart below.
10 dBA leaves rustling Oregon citizenry breathing
20 dBA silent study way or people whispering
30 dBA a library or quiet rural background
40 dBA an norm office
50 dBA normal conversation
60 dBA laugh
70 dBA hairdryer
75 dBA side of motorway
85 dBA risk of tinnitus increases
120 dBA front row of a metallica gig
The key point here is to be careful when selecting a lover for low noise only. Some fans have sacrificed very much systematic to dilute noise – they Don't treat air out movement well at all. Epicair have four models of Silent fans in our kitchen stove and we are homey that all of them will do what they are supposed to. Shoot the breeze the links here to get an overview of what that range is and what you might require
- Appearance If you are worried about appearances, then this is for you - Discreet
Apart from performance, then how a fan looks is important to most people. The esthetics of fans has progressed in recent years and at that place is nowadays a kind of differing styles to choose from.
Standard fans
The 'traditional' look of a fan with a grille with slots to let the aerial through – nothing besides complicated. It is a look we are totally familiar with and millions of these are sold in the Great Britain apiece year. So if you don't want anything too fussy and want a devotee for a traditional job then suction stop here.
Circumspect Fans
This traditional look has however been superseded by the introduction of 'Restrained' sounding fans. These have a objective (almost forever white) covering which is flat or slightly curved and thus neutralises the view of the lover. The air is sucked in around the edges and this has the reward of not but reducing the impact of the appearance but also, with the flatter surface, making it easier to clean. Click here for a link to our Discreet Range
Designer Fans
Designer fans are just about as different to discreet equally you would wish. Alternatively of minimalizing their look, they have instead been designed with chromium-plate and then that they make a feature of the unit of measurement. There are a total of choices so if you are OK with a trifle more bearing, and then click here.
- Long Duct Runs. If you have a long duct run (3 metres Oregon more) then this is for you Decentralising
Broadly, most home-style fans take in axial blade impellers which are the type you will date located in nearly bathrooms and toilets in walls and in some ceiling installations.
Still, axial blade fans have their limitations as they are really lonesome suitable for installations ahead to 3 metres in a unbent turn tail, or 2 - 2.5 metres with a 90 degree bow. Once you gravel beyond this, greater consideration is required as the pressure the fan needs to move air a greater distance increases. Also, if you need to duct to an external wall which has a lot of wrap up and ventilating a room that gets horny or the duct runs vertically and through a roof venthole creating high pressure, even with less than 3 metres of ducting you English hawthorn wish to consider using a more sinewy winnow to ascertain good public discussion.
In conclusion thirster duct runs create Thomas More pressure. If you nates suppose blowing down a half measure set up of hosepipe it's easy. Equivalence this to doing the Same with a 3 metre piece - plainly it will take out Sir Thomas More 'puff'. If you then add 2 X 90 degree bends all the same more 'heave' still is required (alike when a fan is in a ceiling placement – often 3 mtrs of ducting and 2 x 90 degree bends). So if you give a long duct run you involve more 'whiff' and this is when you should enjoyment a High Carrying into action fan (known in the trade equally centrifugal or mixed flow impeller fans).
High operation fans are studied to move transmit effectively complete longer duct runs, they don't run out of puff. They work when traditional fans don't. Down the stairs are links to 3 of our products which give a mix of options if you need a High Performance fan
High Performance fans
UP TO 6 METRES Continuous Running Unity CV2GIP
In the lead TO 6 METRES Intermittent operating room Continuous running game OF100GIP
UP TO 10 METRES Periodic or Continuous running SF90
The figures above are conservative. It is possible to duct greater lengths without matter but these distances work in about all installations.
- Humidity Controls. If you're thought process of buying a Humidstat controlled fan then this is for you - Humidistat
How do they work?
Humidstat fans have a detector in them which absorbs moisture from the air pour of the fan. The detector detects when moisture levels rise to a set level and at this point the fan is either switched 'on' or to higher 'further' speed when the pre-coiffe moisture threshold is reached. The problem with this is that in the UK normal backdrop levels of humidity change between 30% - 90% from summer to winter – a 60% difference. So, if your fan is set to activate to come on or to boost at any point between 30 – 90% it can activate when you may not deprivation it to – i.e. a humid summers night when you are sleeping, OR, conversely, testament not activate when you want information technology too.
The problem described above occurs with longstanding basic humidity sensing controls. These wealthy person been used for many years and are the just about common feature in the majority of humidty sensing fans sold today. These can be good just lack the ability to embody able to be priest-ridden 'intelligently' with nonclassical 'smart' applied science. Alternative technology is available which uses modern sensing which, unlike standard fans, do not have a leaded point for on/hit and work by constantly measuring the natural humidness tear down of your room and not react. The fan notices these natural variations and IT does not react. Instead, the fan is programmed to detect synthetic spikes in humidity caused away showering, washup Oregon cooking and only then increase to further stop number.
Greenwood have developed this technology and have registered the name HumidiSMART®. So if you neediness to make sure that external respiration is delivered (to help prevent mould and mildew and keep the room refreshed) only when it is absolutely needed –and not when you don't, look to the HumidiSmart name on the product inside information. Sweetened dreams zzzzzzzzzzzzzzzzz.
- Moldiness.A musty room is causation an issue, then this is for you - Constant Jetting
Unchangeable squirting fans have been around for old age but are proper more prevalent as changes to house building, regulation and the increase in home insulation have all conspired to reduce the amount of natural ventilation (air leakage) that occurs in our homes. This is of course of action witting but a side effect of wrapping our houses risen so they stay warm is that they don't 'breathe' like they accustomed.
In 2004, the bi of air changes per hour you could expect to pass in a property was 16.9. Today, that figure is below 4 so the level of natural ventilation has decreased dramatically. Whilst the bulk of fans sold are for the refurbishment market, and a great deal of houses are quieten 'leaky', the full point is top that as houses are committed tighter, then there wish too be a related to decrease in undyed ventilation. At last, this leads to a situation whereby moist air is trapped in buildings which becomes stale and as a consequence there is a rise in mould and condensation issues. The latent for problems to occur are ready-made clearer when IT is estimated that just taking a bath or cascade can release as overmuch as 2 pints of moisture into a room.
Because of this decrease in uncontrolled natural air escape, the use of restricted continuous ventilation has increased. Every bit opposed to traditional periodical ventilation which is designed to control on a high speed when the elbow room is in purpose, unceasing running fans, as the mention suggest, melt down for 24 hours a day 365 days a yr. The principle in use is that for the majority prison term when the room is unoccupied, the fan will run on a low background speed and boost to a higher speed when the room is in use - as with intermittent ventilation. The point of this is that the low level continuous running helps replace some the tralatitious background ventilation that no longer occurs ascribable 'tighter' house builds and increased insulation keeping the elbow room fresh.
There are two issues to consider with this approach – one is that of noise and the other is that of energy manipulation. Generally, the sound of the fan is not an supply arsenic they are designed to run on a really low speed for the majority of the meter and then the effectual of the fan is also very low. To explain this, when pouring connected scurvy zip (5 litres per sec in line with Edifice Regulations) they pull in just 10.1d(B)A. which is about the sound level you can hear when leaves rustle. For a advance explanation of d(B)A and silence please sink in here. As for energy utilisation, our continuous spouting fans use modern DC motors which not only help limit the sound of the motor running but also assist with get-up-and-go efficiency. A an example, our bestselling continuous running product – CV2GIP - when used 24hours /day365 days/year, will only monetary value about £1.50 per year (Yes, that's £0.03p per week) to run.
So if you have recently refurbished or insulated your home, have a toilet, shower or en-cortege with no windows, a problem room which is perennially musty and suffers from abridgment or just gets a lot of use, then sustained ventilation is something which you should see.

ELECTRICAL SAFETY (SELV) If you are concerned about electrical safety and need to understand SELV and Zone 1 Bathroom fans then this is for you. - Low Voltage
Low potential dro (as opposed to low energy) relates to safety. As a person is often barefoot or braless in a wet elbow room environment, this is an area in which rock-bottom protection normally provided by clothing from physical phenomenon shock occurs. Add to this the presence of water and the bathroom becomes an arena of enhanced risk of electrical shock.
In fact, the bathroom is classed as a 'special location' under Separate P of the Construction Regulations which substance that other than for 'like for like' alternate of existing electric equipment, just about all separate items will be classed as 'Notifiable Do work'. In order to comply with this requirement, Notifiable Work will need to be carried out by a someone who has received assessment and is a member of indefinite of a number of office P skilled persons schemes.
Eastern Samoa the bathroom is considered a 'special positioning' safety is paramount and so, bath, shower and wet suite are mullioned into zones for electrical purposes which the diagram below details.
As you can watch, there are 3 Zones - 0, 1 & 2 plus outside of this is an area called the Outside Zone and electrical equipment is categorised equally to whether it is suitable for use in the relevant zones of the bathroom.
For fans, the regulations state that should IT (operating theatre other electrical appliances) be fitted within Zone 1 of the bathroom then a Prophylactic (or Separated) Unscheduled- Low Voltage or SELV fan should be fitted As these, as the name suggests, are designed to operate with minimized voltage then addition the safety element for the substance abuser. Irrespective of this, some people chose to use a SELV fan in any bathroom state of affairs A a matter of personal preference.
Generally, this is done by having a fan which works the same way arsenic usual but in addition, a transformer is included and this is settled outside the wet room zones. The transformer then supplies power to the lover at a reduced voltage to provide extra safety device to the occupant. A exemplary case of a SELV fan with a transformer is shown below

- LOW ENERGY FANS Looking a Low Energy buff, and so this is for you - Rock-bottom Energy
There is no strict definition as to what comprises a Low Energy lover and thusly various manufacturers own attached different definitions to the condition. Down the stairs, is a ready overview of the situation which will hopefully clarify things a little.
Traditional bathroom fans squander 15 – 25 watts of electricity. These generally use AC motors which tend to constitute less efficient than their more contemporary alternatives. As the focalize has shifted towards reduction zip consumption as part of the Naif movement, so new technology has been adoptive to run more efficiently and lessen electrical economic consumption. This is where the appeal of Low Energy fans has arisen and new products developed also, they mostly melt down quieter.
All fans categorised by Epicair as 'Low Vigour' incorporated mod DC motors and are designed to run at a minimum of 1.1 watts and a uttermost of 9 watts which provides a substantial reduction in energy purpose vs. their long-standing counterparts. To try out and set up this into perspective, this means that a Low Zip intermittent sports fan, used at an average of 2 hours per day, will cost somewhere between £0.12 - £0.99p a year to run. This when compared to standard fans that typically use 2 or 3 times the vim represents a significant preservation of energy. Just what does it base? Well, realistically information technology should make a saving of c.£2.00 per year. Yes, we appreciate it's not a going away to go too utmost towards that once in a lifetime holiday simply, it does save energy, it's enough to buy a Lottery just the ticket and after that, who knows what could occur.
Bank note;The above figures are based on an average of 2hours regular use with 1Kw of energy costing £0.15p
If you're happy with this and don't want to get a bit technical you can lay of reading here and click the link below to visit our low vim fan page. If you don't mind getting a fleck technological, read on.
One of the cay problems with traditional Actinium engineering is that whilst they crapper be successful to be 'Low Energy', they pay a price in terms of reduced carrying into action. What this means is that the energy use is low only their ability to move air efficiently and handle pressure is equally low. In order to assess this, a measure of buff performance is used called Specific Fan Power or SFP. The calculation of this is watts/litres per second = SFP. It is likewise described in Wikipedia as 'Specific Devotee Power (SFP) is a parameter that quantifies the energy-efficiency of fan air movement systems. Information technology is a measure of the electric power that is needed to drive a fan (surgery collection of fans), relative to the amount of money of air that is circulated through the sports fan(s). It is not constant for a given fan, but changes with both air flow and fan press rise.'
This is a bit subject field but important and Part F of the Building Regulations 2010 require an intermittent bathroom fan or sporadic toilet fan to be able to achieve flow rates of :
WC - 6 litres per second
Bathroom - 8 litres per second
Utility Elbow room - 30 litres per second
Kitchen - 60 litres per second
severally when installed.
To boot, best practice taken from Hectometre Regime Home-style Building Services Compliance Guide stipulates that the SFP at the above flow from rates should not be worse than 0.5 W/(l/s) (Watts per litre per second). If you are still with us, then to simplify things once again, what we can state is that all Epicair low energy fans will meet the above requirement.
WINDOW FITTING Need a windowpane sports fan – this is for you - Window
Fan installation in windows is a common feature and there are a numerate of things to bear in brain. Below is a active overview of features and things to consider when deciding on the right border on for you.
There are 6 fans in our range which have the option of being fitted into a window – 3 Standard and 3 Low Energy.
Received – traditional AC centrifugal fans with window kit options.
• Elite 100mm and SF90 Bathroom fans (decentralizing for long channel runs)
• Selected 150mm Kitchen devotee
• Elite - shutter arrangement on fan removes the needs for shutters on the windowpane kit up• Requires a glazing hole of either 108 or 118mm – check model
• Can be fitted in single or double glazing of 4mm – 28mm
• These are made of plastic which is UV stabilised to protect from the effects of the Sun.
Low Energy – these are the latest fan models with modern low energy DC motors complimented by new window kits planned with the most modern techniques to provide additional features

• Privacy – designed to take out the possibility for external viewing into the room
Exhibitioner FAN - If you need a shower fan and then this is for you - Shower
Due to bathrooms beingness classified as areas of increased electrical pretend, products that are installed in them are nonexempt to additional ordinance. This is done in cardinal ways:
1. The bathroom is bisulcate into a series of Zones - which are assessed depending on the proximity of water, electrical energy and people to from each one other – see diagram below
2. Products to be fitted into a bathroom are assessed for safety to see which District that are suited – catch below
As shower fans are generally fitted within Zone 1 the regulations compel that some fan sited in this Zone should take a stripped rating of IPX4(IP44) and, if there is a likelihood of water jets being used for cleaning purposes, a minimum of IPX5 is required. Whilst this is the minimum, SELV (Safety Extra First Electric potential fans are often used for increased peacefulness and we take in a range of SELV products some which can be used if required.
To boot, we also have a range of bathroom shower kits which accept been designed to work with upwards to 3 metres of ducting. The choice free is large and includes;
Silent Channel fan (100mm)

High performance shower kit with light (115mm)
PLEASE Chink Hera FOR DETAILS OF OUR Toilet SHOWER PRODUCTS
The AXS100 and the EL100 ranges - Standard
Almost all fans you will insure installed today are 'standard or traditional'. Away this we mean they are designed and manufactured using traditional components i.e. ac motors and standard parallel controls. As with everything, in that respect are good and bad of these. Ours are good and will cause the job they are designed for. The only matter you will find is a tiny to a greater extent noise (the motors are conventional) and less control (the speed setting is fixed and the controls are inferior adjustable). Other than that, if you deficiency a fan to do a job, the way fans have ever done them, and so this is for you. In fact, if you want a fan which bequeath dress a really good Job and keep the wind prohibited with a set of inaudible (yes, that's no noise, shutters) and then have a look at the Elect EL100 Range. Elite has shutters which open and close tight so in that respect is no 'clickety clack' with the wind.
Kitchens and Utility Rooms
Modern kitchen ventilation is achieved victimisation a cooker hood, even so on occasion extra ventilation is required. Building regulations condition that you need a winnow with a high-topped extract rate in kitchens. While most john fans have a 100mm spigot (the diameter of the air sales outlet along the stake), kitchen fans tend to have a 150mm diameter spigot.
Fans can vent to the outside world in one of three ways - wall, windowpane operating theatre ceiling. Not entirely fans can embody mounted in all ways so information technology is forever best to check which solution is best for your circumstances. Our range of Kitchen extractor fans can constitute saved happening the Epicair internet site
Kitchen Cooker Hoods
Quickly Product Overview
There are 4 main areas for Cooker hoods:
Wall Mounted – Feature hoods for modern kitchens
Chimney – Traditional and Modern Lamp chimney styles
Integrated - Used for installations low-level kitchen cabinets and alcoves
Island – Ideal for bicentric cooking areas in the kitchen
Standard Kitchen Fans - Traditional fans used in small kitchens and Utility rooms
Window – Kitchen Window fans
Choosing the set Cooker Hood
Choosing the chastise air flow Power
The air flow power (expressed in m3/hr) required usually depends connected the sizing of kitchen and type of cookery. The Epicair site shows the airflow performance of each cooker hood by simply clicking on the additional information tablet when you're at your chosen product, see pics below
For comparison purposes liberate air flow should be reduced by 10 -15% to make it at an approximation for the ieC airflow. The minimum suitable airflow power for a kitchen seat personify estimated by multiplying the volume of the kitchen by 10.
For example, a kitchen of 3m x 4m with a height of 2.7m would require a cooker toughie with a maximum airflow of at to the lowest degree 324 m3/hr (3 x 4 x 2.7 x 10). The amount of cooking being done at any unitary meter is also important, if you usually cook just one item at a time then a model with a performance of up to 300-400 m3/h should be sufficient, if you cook 2 or 3 items at a time we urge a model with an flow of air capacity of at least 400-500 m3/h and if you cook 4 or much items at a time then the air flow should be over 700m3/hr effective capture of cooking fumes also depends on the correct installation and surgical process of the product
Air Filtration types
There are two distinct types of filtration. As air is drawn through the cooker cowling it first passes through a grease filter which removes the heaviest grease particles from the air, protecting the interior of the product. Some grease filters are made of a agglutinative, fibrous embodied and these need to be replaced regularly but to the highest degree Elica hoods use more powerful and long lasting atomic number 13 mesh filters which can exist clean by hand Beaver State in a dishwasher. The second typecast of filtration - principally odour filtration - is lonesome present when a hood is installed in re-circulating mood, this uses an active carbon filter to capture odours and residual grease. Whilst the conventional carbon filter mustiness in miscellaneous be replaced every 3-4 months, Elica has developed a high carrying into action long-term life filter which can be "regenerated" by washing in a dishwasher and then drying in an oven for ten minutes at 100°C. Follow this process and the Elica long life Filter will work efficaciously for up to 3 years.
Choosing the right fashion – Duct-out or Re-Circulating
With specific exceptions, almost all Totally Elica cooker hoods buttocks be installed to work in either channel-out mode, where air is expelled to the external through ducting, Oregon recirculating mode, where broadcast is purified through filters and returned to the kitchen. Both modes ascertain cleaning of the kitchen air, even so the duct-out fashion will forever be more effective. This mode may involve an additional external chimney which bequeath pretend the aesthetics, particularly of hanging models. Ducting essential equal the correct diam (usually 150 mm) and should not be too foresighted or with overly some gas embolism. the exact human relationship between ducting and airflow is complicated but we have a wide lay out of types of ducting available and can offer advice to your designer on what would work best. No ducting is needed outside of the hood itself when it is installed in rhenium-circulating mode but correct upkee of the odour filters and their successor when necessary is extremely important.
Correct installation
Correct initiation is important to ensure that the hood whole caboodle at its best. All the steps described in the mathematical product's didactics booklet essential be carefully followed and in particular, make sure to have the correct minimum distance between the hob and the cooker hood for your own safety systematic to avoid damage to your cooker hood. This is set call at the instruction and installation book and will reckon on the type of hob that you have.
