Choosing Bathroom Extractor Fans
Think about where in the bathroom the fan will sit, how its run-on should be controlled, and which finish suits the room.
Where the fan goes
For a Zone 1 installation, pick a fan that is IP45 rated and suitable for Zone 1: the EX1TBK, EX1TWH, EX4TSS and EX5TMB. The EX1THWH and EX3TWH are IP45 rated as well. The EX001T is designed for wall and ceiling fitting in kitchens, bathrooms and toilets.
Choosing the control
The EX1TWH, EX3TWH, EX4TSS and EX5TMB let you set the overrun anywhere between 2 and 30 minutes, and the black EX1TBK arrives preset at 2 minutes. The EX1THWH pairs its overrun timer, set between 1 and 30 minutes, with an integrated humidistat for efficient moisture control.
Matching the room
For a fan that adds to the look of the room, the EX3TWH in matt white, the EX4TSS in stainless steel and the EX5TMB in matt black have a built-in LED lighting effect while they run. The EX1TBK is a black timer fan with a built-in back draft kit, and the EX4TSS has a slim profile and attractive facia.
Fitting and wiring
The EX001T, EX1TBK, EX1TWH and EX3TWH are double insulated, and the EX001T, EX1TBK and EX1TWH need no earth connection. The EX1TWH runs on 230V 50Hz at 9.7W, and the EX3TWH and EX4TSS at 10.1W. The EX1TBK, EX1THWH, EX1TWH, EX3TWH, EX4TSS and EX5TMB comply with Building Regulations Part F and Part L.

How do I choose a bathroom extractor fan?
Start with the position: for Zone 1, choose the EX1TBK, EX1TWH, EX4TSS or EX5TMB.
