Axial type fans cause gas to flow through in an axial direction which is parallel to the shaft where the blades rotate, making the flow axial at exit and entry. Axial fans are designed to create a pressure difference and force which produces a flow through the fan.

Extractor Fan Humidistat & Timer

Humidistat & timer operated

These extractor fans are certainly the cleverest with the ability to operate using a timer or based on the humidity levels in the room. It is operated when humidity levels within the room get too high or when the light switch is used, with a timer continuing to run the extractor fan for a predetermined amount of time.

    5/ 5

    Used this to replace a broken 20 year old bathroom fan, installation was very plug & play with fixing positions and cabling in the same place. When I switched it on I had to double-check that it was actually running, it was so quiet. Performance seems good (it's only on low speed currently but seems to do ok). One thing to be aware of is the requirement for access to both sides if the fan in order to remove the cover; mine's in a corner which makes this quite difficult. Overall I can highly recommend this product.

    Very good value from Plumbworld...30%+ cheaper than Screwfix. Delivered on time, and fitted easily...replacing same fan that only lasted about 3 years. Warranty is 2 years. Item is as described, works well and, despite what some others say, I found it to be very quiet. 4 Star due to dubious reliability. Plumbworld excellent service and price.
