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. 61 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 61 litres per second! That’s over 4x what’s recommended! IPX4 Rating This product has a rating of IPX4 which means it is protected from water splashes from any angle. 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.   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. These ratings are determined by specific tests. These extractor fans can be fitted within Zone 1 as shown below. 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.  Fixing kit included Included with this in-line extractor fan is a wall fixing kit. This installation kit includes the necessary ducting and fascias for getting your fan fitted quickly and easily. Kitchen & bathroom suitable With high extraction rates this extractor fan is suitable for use in both a full family bathroom and a kitchen environment.  3 Year Guarantee When buying anything for your home you need to know that its going to stand the test of time.
