Overview

The ST100PIR is an exceptional extractor fan. Using an IP45 rated motor, it is "resistant to jets of water from all angles" and can therefore be installed anywhere in the bathroom. Very powerful and quiet, it is also very energy efficient, using only 8w on full power. The ST100PIR comes with an integral PIR (passive infra red) sensor which automatically operates the fan when it detects movement up to 4m away.

Quite simply and without any doubt the best bathroom fan we have ever tested. The ST100PIR is one of the most powerful, most energy efficient and quietest four inch axial fan ever produced. It is incredible to find these three, seemingly opposing attributes in the one fan. The fact that it is also IPX5 rated and can be installed anywhere in the bathroom without requiring a separate transformer is just fantastic.

The ST100PIR features an integral PIR (Passive Infra Red) sensor which automatically detects movement and switches the fan on. This is particularly useful in properties where bathroom users may neglect to turn on the fan or where situating an appropriate switch is difficult.

The Silent Tornado may be ducted up to 5m in a straight run or 3m with with 2 right angled bends and can therefore be installed on the ceiling and ducted through the loft without compromising performance.

In summary, the best bathroom fan on the market by quite a distance and the manufacturers are so confident in its performance and reliability that they offer a full five year guarantee. Furthermore it comes to market considerably cheaper than all comparable models which it comfortably out-performs and represents fantastic value. We highly recommend this fan.
