Bathroom extractor fan come in two main types; Mains voltage extractor fan and SELV or Safety Extra Low Voltage extractor fan and it is vitally important that the correct fan is installed. Since electric and water make for a fatal combination strict regulations were introduced dividing the bathroom into 4 zones, 0 - 3. Mains voltage extractor fan may only be used in Zone 3 of the bathroom. In Zones 0, 1 and 2 SELV fans (12 volt) ONLY must be used, with the transformer being housed in Zone 3.The regulations governing extractor fan in the kitchen are less strict than those for the bathroom and are concerned with the amount of air that is to be removed (air extraction rate), rather than user safety and voltage. The minimum air extraction rate is 15L/s.
