2 Year Guarantee Timer controlled Extractor fans with a built-in timer control means that the fan will operate with the bathroom light switch and then overrun for a set amount of time to continue removing moisture from the air. This is great for steamy bathrooms, allowing you to turn the light off but continue with extraction for a short time. Enjoying a peaceful bath or shower just got easier with these excellent Airvent extractor fans. Take the hassle out of life with a timer or humistat controlled extractor fan or choose a classic switch or pull cord. With Airvent never again will you have to worry about damp and mould colleting in your beautiful bathroom. 24 ltr/s extraction rate Building regulations stipulate that extractor fans need to be able to extract at least 15 litres of air per second. It’s needed to ensure a minimal build-up of moisture in the room, reducing mould and grime in damp areas. This fan will extract a crazy 24 litres per second! That’s almost twice what’s recommended! Inline Design Inline fans are installed within your attic as part of your ducting system. An advantage of inline fans is that one fan can be connected to more than one inlet ducts which are in different areas, and the inline fan can ventilate both locations, so you don’t have to install more than one fan unit. Direct extraction from moisture source Because of the way that in-line extractor fans are designed you can have them fitted in the loft so the duct point can be directly above the shower or bath. This means that any moisture can be extracted at the source, reducing steam and mould build-up.  IP44 Rating This product has a rating of IPX44, meaning it is protected against solid objects larger than 1mm (wires, nails, screws) and is protected against water splashes from all directions.   Zone 1 Rated IP rating stands for 'Ingress Protection rating' and this helps us determine what bathroom electricals can go in particular bathroom zones. An IP (Ingress Protection) number or code is used here in the UK to specify the environmental protection of enclosures around electronic equipment.
