VENTILATION SYSTEMS
LUCY HOLLAND, AT SUPPLY PARTNER AIRFLOW DEVELOPMENTS, EXPLAINS WHAT FEATURES YOU SHOULD LOOK FOR WHEN SELECTING AN EXTRACTOR FAN… Which type of extractor fan should I install? T he Building Regulations Approved Document F - Ventilation, sets minimum flow rates that an extractor fan installed in a wet room should be able to deliver when correctly installed. The minimum airflow rates are as follows: • 6 l/sec for toilets • 15 l/sec for bathrooms • 30 l/sec for utility rooms • 60 l/sec for kitchens. (30 l/sec in kitchens when the fan is installed adjacent to the hob – this is also the minimum flow rate expected from a ducted cooker hood) Having considered the application of the ventilation required it is important to select the correct type of fan to meet the requirement fully. Axial Fans are ideal for through the wall, ceiling and short run of ducting applications. While providing high performance from a slim profile they work against limited back pressure so are recommended for use with flexible ducting not exceeding 1.5m in length with a maximum of two 90 degree bends. Mixed Flow Fans for wall and ceiling combine the convenience of an axial fan size with the performance of a small centrifugal fan making them ideal for short to medium duct runs. Centrifugal Fans are quiet, powerful and suitable for wall and ceiling applications. They work well against system resistance making them the perfect choice for efficient performance for longer duct runs. Safety Low Voltage Fans (SELV) Axial, Mixed Flow and Centrifugal Fan variants operating from 12v or 24volt supply which may be installed in accordance with IEE wiring regulations.
