Impeller Fans, Multivane, Disc, Runner and Squirrel Cage are all made use of to explain blowers or fans depending exactly what nation a person is from. In the United States, the terms used are blowers or fans. Usually a blower is a centrifugal device with some type of wheel and fans: impeller is an axial device with a propeller.

An Axial fan is the type you are probably to see, and have actually fitted by a builder or electrical contractor if you ask them to fit a fan for you. Many restrooms and kitchens across the UK will certainly have an axial fan of some kind fitted. The fan blade itself is mounted on an axle from the motor, a bit like an aircraft propeller, and draws air through the blade linearly and presses it out the back of the fan body through what is referred to as the spigot.

The majority of average fans of this type have a circulation rate of around 75 m3/h which is great for most little bathrooms with a brief run of duct through the wall, no greater than a metre. There are some that can draw as much as 97m3/h and can be ducted as much as 5m, but all axial fans work best on a much shorter duct run. By design, axial fans do not cope with long terms of duct as they lack the pressure needed to press the air a far away and reach a stall condition where the air in the duct not moves. When incorrectly installed on a long run of duct, this can be a reason for early failure.

Standard domestic axial fan sizes are four and six inch, 4 inch for a bathroom and six inch for a kitchen area. UK building policies require that 60 litres per 2nd is drawn out from a kitchen, which a six inch axial fan will provide. 9 and even twelve inch variations are readily available, however these are more for office usage, supplying a much greater flow rate however likewise much more sound.

A centrifugal fan is a bit different. Its blade is a drum or round plate configuration with blades, or ribs attached around its circumference with a space in the middle, this is called an impeller. It moves the air by pressing it down an exit duct in the fan casing at 90 degrees to the impeller itself as it turns, air then hurries to equalise the absence of air pressure through the centre of the impeller, which is then pressed out of the duct and the cycle continues. This creates much higher atmospheric pressure, with greater performance.

Due to the higher pressures involved, centrifugal fans are much better able to deal with longer runs of duct. Some domestic centrifugal fans can be ducted approximately fifty meters and still offer ample extraction. These fans will still only supply around the same 90m3/h that a 4 inch axial fan can accomplish, however the pressure is maintained over a much greater range. If you have a duct run that is over a long distance, through a ducting system in a flat for instance, or through a roofing area with a number of bends, a centrifugal fan will cope far much better than an axial fan.

Axial fans, when used as intended will offer outstanding results with minimal sound, nevertheless a centrifugal fan attains greater distances, however will certainly produce more sound in operation.
