Since electric and water could make for any fatal combination, strict rules were introduced dividing the restroom into 4 zones: , 1, 2, 3. Zone is incorporated in the bath. Zone 1 stretches up and down 2.25m over the bath. Zone 2 stretches in most directions for .6m from zone1 and zone 3 stretches laterally for just two.4m from zone 2.
It is crucial that you simply install the right fan within the correct zone. Bathroom fans are available in two currents Mains current (240v) and SELV or Safety Extra Low Current (12v).

Axial fans are the type that you're accustomed to seeing on walls and roofs and generally have air extraction rates which is between 85m3/hr and 95m3/hr around the 4 inch models. They are appropriate for standard installations in which the fan will probably be ducted with the wall. Centrifugal fans are usually (although not always) inline duct fans. (see previous section). Centrifugal fans are often a lot more effective than axial fans with air extraction rates which is between 110m3/hr and 220m3/hr around the 4 inch models. Centrifugal fans are particularly suitable to installations where lengthy duct measures are needed. The Vent Axia Solo Plus, for instance, may be used in duct runs as much as 50m!
3. Dimensions of toilet fans
Domestic bathroom extractor fans are available in two dimensions: 4 inch /100mm and 6 inch / 150mm. In nearly every situation a 4 inch bathroom extractor fan will suffice.

Measured in 'Litres per Second' (L/s) or 'Metres Cubed per Hour' (m3/hr), the environment extraction rate of the bathroom extractor fan is among the most significant factors. Your Building Rules stipulate that the bathroom extractor fan must extract a minimum of 15L/s inside a standard domestic bathroom. Most 4 inch bathroom extractor fans far exceed this minimum requirement, and nowadays the conventional is 85m3/hr. Any bathroom extractor fan by having an extraction rate of 90m3/hr or over might be considered effective.

Typical dB dimensions for axial bathroom fans range from 35dB(A) and 45dB(A) using the more effective centrifugal bathroom fans between 40dB(A) and 55dB(A). Although centrifugal fans are even louder, it ought to be appreciated that they're located within the attic space and they are insulated and additional away, lessesning the amount somewhat.
