What is the Quadra HTP for?
It's a continuous-running centrifugal extractor fan for bathrooms, toilets, utility rooms and kitchens, keeping the home fresh and free from condensation and mould.
How is boost triggered on the 439251?
Via the built-in pullcord or an external switch, each with an adjustable run-on timer. (For automatic humidity control, choose the 439181 humidistat version.)
Why a centrifugal fan?
Its centrifugal impeller develops more pressure than an axial fan, so it performs well on longer or more restrictive duct runs.
How much does it cost to run?
Its Lo-Carbon motor gives up to 90% energy saving over a traditional fan, under 10p per week even running continuously.
Does it need filters?
No, it uses filterless technology, so there are no filters to replace. Annual cleaning of the cover and impeller is all that's needed.
Is it suitable for a bathroom?
Yes, it's IPX4-rated. As a mains fan it should be installed on a suitable circuit by a qualified electrician.
