Inline Mixed-Flow Extractor Fan FAQs

What is an inline extractor fan?

An inline extractor fan, otherwise known as an inline fan, is a fan that is usually installed in homes with rooms where moisture is present in the air. In particular, they are used in bathrooms, kitchens and laundries. These inline duct fans push air through the ducting and therefore create positive pressure, which takes excess heat and moisture out of the room, through the ducting. Therefore, it is used for regulating temperature as well as excess moisture in the air within the specific room.

What is a mixed flow extractor fan?

A mixed flow fan refers to an in line duct fan with a highly specific impeller system. In particular the impeller system makes use of centrifugal and axial impellers, which has the effect of creating a greater exhaust pressure, thus taking excess air, moisture or heat outside of a room and releasing it elsewhere. The mixed-flow fan also gets its name from being able to work at high speed while emitting very little to no sound, resulting in the product also being called a silent inline extractor fan or a quiet inline extractor fan.

How do inline duct fans work?

An inline centrifugal fan contains blades that spin, causing a centrifugal force. This force from the blades pushes air from one room into the ducting, piping or ventilation system of the home to remove excess air, moisture or temperature.

Where to install an inline duct fan

There are several places where you can install ultra quiet inline fans. The first option is to install it between two sections of ductwork. Here, the air flows from one part of the ductwork onto the next and that is how it is extracted from the room in question. The second option is to install your 100mm inline extractor fan near the source of ventilation. An example of this is placing it on or near the ceiling so that it can absorb odours and moisture in a bathroom. The third option is to place the fan at the end of a duct, where the positive pressure created can be released after it is pulled through the piping or ventilation system.

How to install an inline extractor fan

If you are planning on replacing an inline extractor fan, it is worth knowing that replacement is quite simple and can be done where you remove the wiring (Ensure this is done by a competent qualified person) then simply remove the fan and replace it by following the manufacturer's instructions. However, in other cases where you are installing a new inline extractor fan, you need to carefully select the proper location for fitting it by examining where the source of moisture and odours mainly come from. For example, in a bathroom with a shower and a bath, you may wish to place the inline fan somewhere in the middle. If it is only a toilet, you may wish to place your inline fan above the door to the room. Relying on professional advice and service is the recommended route to take.
