This QuietAir Humidity/Timer Fan carries the Quiet Mark Approval and is part of an extended range of elegant, discreet axial fans that are extremely quiet with various control options that activate the fan only when needed - the choices are: remote switching, timer, humidity with timer and motion sensor with timer.

This Humidity/Timer model has two ways of activating, it is activated by a rise in the level of humidity and it can be connected to a switch, it can be connected to the same switch as the light circuit or it can have its own switch. There is also the option to use both of the QuietAir speeds, a separate three way position switch should be used to achieve this, see our product code 9041315 Model 3POSSW.

This 100mm version is fitted with:

An adjustable humidistat of between 60 - 90% RH

An over-run timer which can be set at 6, 12, 15 or 21 minutes making it ideal for use in larger bathrooms, utility rooms and living spaces, giving 75% more flow from an only slightly increased fan footprint.

A 2 minute delayed start - leaving a delay of 2 minutes before the fan operates - ideal for quick night time visits to the toilet

Two speed options - to adjust for individual requirements,

An integral flow straightener,

Back draught flap and

Clip-on cover for ease of cleaning

When installing this fan you need to select which of the two speeds you want it to operate at if not using the three way switch above. This fan has various settings; these are adjustable by way of the dip switches located under the cover. The adjustable settings are: delayed timer on/off, the delayed timer function, you select the amount of run on time after switching the fan off, adjust the level of humidity that activates the fan and you can also turn off the humidity function. It comes factory set and you only need to access the dip switches if you want to change the factory settings. More detail is available in the wiring instructions included in the box.

The QuietAir range is designed to provide powerful extraction levels that exceed the requirements of the latest Building Regulations. Fans ideally should be quiet when they operate but not at the cost of performance. This fan will perform to Building Regulations Installed Performance requirements, on BOTH speeds. Therefore when you take into consideration the noise level and energy consumption of this fan in relation to its performance then the QuietAir is class leading. This fan has also been designed to deal with a longer duct run when compared to other axial designed fans. To achieve the longest duct run rigid ducting should be used and not flexible ducting. Where flexible ducting is used the radius of the pipe must be maintained as well as being pulled very tight to reduce resistance. An extractor fans location in a room is important for it to perform; it ideally needs to be the furthest point away from where the replacement air will enter the toilet, ensuite or bathroom. In most cases the replacement air comes in under the door of the room, important that the undercut on the door meets the Building Regulations for air to flow in.

This fan can be mounted in the wall or the ceiling, where there is reduced depth in a ceiling application then part of the spigot vane on the back of the fan can be removed and reinstalled after the bend. It is important that if the duct run is long (more than 1m) that the spigot is reinserted as this helps the flow of air. This fan is fitted with a back draught flap that can be removed if you already have an external grille that provides this function.
