Airvent 457086A Bathroom Extractor Fan with Timer Domestic 100mm 4" Axial Toilet Fan

Product Information

Mechanical extract ventilation (MEV) is a continuous ventilation system. This can be either a whole house centralised MEV system, or localised decentralised MEV (dMEV) fans. Zone 3 (including Outside Zones) allows installation of any type of IP rated bathroom extractor fan as it is a safe enough distance from the sources of water in your bathroom. dMEV fans are individual room fans which operate continuously to draw moisture from either the bathroom, kitchen, utility room or other wet room. To avoid dampness and mould entirely, make sure your fan exits outside. How much does a bathroom extractor fan cost?

One of the most common complaints made about extractor fans is that they are too noisy. If this is a concern of yours, you might find our Xpelair Simply Silent range is best for you. These have been specially designed to reduce noise, thanks to their silent running ball bearing motors. The sound they make is measured on the decibel scale and can be as low as 30dB - the equivalent of a whisper. Leaky bathroom extractor fans can cause cold air infiltration, increasing energy bills and reducing ventilation efficiency. Many of the better systems also have dampers on the ducts to limit the air flow in strong winds. This does add a bit of ‘active’ control but it also avoids the issue of over ventilation.

Pull Cords are available for operation without the light being on. These are usually the same as the Basic units but allow you to use them separately whenever you need to.

If your bathroom is a long distance from an external wall, or you are fitting it in the ceiling, you will require a longer 'duct run’. This also means you will need a more powerful fan - usually a centrifugal fan. The Domestic Ventilation Compliance Guide describes the whole house ventilation rate for homes as follows: 1 bed homes: 13 l/s, 2 bed homes: 17 l/s, 3 bed homes: 21 l/s, 4 bed homes: 25l/s, 5 bed homes: 29l/s but a minimum ventilation rate of 0.3l/s per m2 of floor area (including all floors) must also be maintained.Choose from over eight brands of roof tile vents from the likes of Marley, Kloberand Hambleside Danelawto reduce condensation in loft space and ensure an extended roof life span.

The most common types of bathroom extractor are either Axial , Centrifugal or inline . Axial extractors connect directly to external walls whereas centrifugal are primarily designed for internal walls with longer runs of ducting. The uplift includes a new requirement that when any improvements, extensions or renovations are done to a building, the ventilation is no worse than before the works began. The works must also comply with all regulations concerning controlled services such as cookers, boilers, fires or electrics. Stopping cold air from entering your bathroom through the extractor fan may seem daunting, but it is a necessary step towards a more comfortable and energy-efficient home. If you have an old bathroom with only a window as a source of ventilation, it might still be a good idea to provide extra ventilation. If, for example, mould or dampness are persisting issues, a fan can help reduce their effects. What are the benefits of a bathroom extractor fan?Add that to the fact that many of us are now spending a lot more time at home due to flexible working or permanently working from home and you have the perfect storm for stale air. The second relies on wind pressure. Prevailing wind creates a positive pressure on the windward side of the building and a negative pressure is created on the leeward side of the building as the wind moves away from it. The combination of the positive and negative air creates an air flow through the home as it pushes from one side and pulls from the other. In leaky homes this effect takes away the warmth in the home very rapidly, but if designed properly it can provide a very good ventilation solution. Don’t forget to insulate the ductwork. Insulating just the extractor fan unit may not be enough to prevent cold air from entering your bathroom. Insulate the ductwork as well to ensure complete insulation.
