To find out which Airflow Fan is the best for you(at home or at the office, interior extractor fans), read the previous article entitled, What type of Airflow Extractor Fan do you need – what do the regulations say, what’s the best fan? The Airflow Extractor Fans should be positioned in such a way that they give an optimum flow of air through the whole room and they avoid pockets of residual air. The location of planned or existing door and window openings must be considered as well as sources of odours, stale air or condensation. Grilles may need to be installed to allow air into the room, particularly with inner rooms which have no windows and tightly sealed doors. The Extractor Fans should be mounted as high as possible, well away from primary heat sources such as gas water heaters and boilers.
The IEE regulations specify the installation of fans within bathrooms and showers by identifying a series of zones. The IEE regulations must be adhered to for all electrical installations.
