High Powered Centrifugal Fans

Why should you replace an extractor fan?

A full range of high powered yet quiet centrifugal extractor fans.

Designed to move air over long distances through a 100mm / 4" hole, centrifugal extract fans give maximum performance even against pressures caused by long lengths of ducting & resistance by grilles.

The Manrose CF100 & the Manrose CF200 ranges are designed for bathrooms, toilets, cloakrooms & utility rooms, while the Manrose CF400 model is designed for kitchens & commercial applications, such as restaurants, hotels & offices.

All models are fitted with built-in spring operated non-return flap into the discharge spigot to stop backdraughts.

All units are manufactured using high impact ABS thermoplastics for strength, durability, aesthetics & easy cleaning.

Centrifugal Extractor Fans

The range of centrifugal fans have been developed as a powerful extractor fan designed to extract from areas that require quick and continuous air extraction from some hard working spaces. Companies like Manrose have developed extractor ranges which cover the spectrum whilst being quiet and vibration free in their operation.

The smaller ranges are designed for bathroom and toilets and similar operations. The smaller models are designed to move about 90 cubic metres or air per hour. The larger units are designed for kitchens and commercial restaurants, hotels, offices and other applications and they are designed to move about 230 cubic metres of air per hour and there are intermediate fan sizes in between. It really is a case of working out the size of the space required and the number of air changes per hour that is required and fitting the appropriate unit.

The latest technology of these fans is geared around providing a powerful fan that will get rid of those unwanted smells and re-freshen the atmosphere quickly and quietly. These fans have the advantage of being designed to move the extracted air over long distances using long lengths of ducting and pushing the extracted air through grilles or other obstructions without reducing the performance of the fan unit. The extractor fan units are built of ABS thermoplastics which can take a high impact without damage and are easy to clean but still look good.

The smaller models have single phase induction motors with pre oiled bearings which give a long life and should be maintenance free. The largest models use a dynamically balanced external rotor motor with a ball bearing system for a life which is claimed to give over 40,000 working hours of maintenance free operation. All extractor fans of this design have to comply to 2006 Building Regulations on Ventilation. The advantage of units of this size and power is that you can fit them to the centre of where the problem is based and fit ducting to take the extracted air away to an exit point which is most convenient and which will cause no offence people next door. This is carried out with no reduction in the performance of the extractor fan.

The commercial or production units that will use these units will find that they are very easy to fit and the cost of such units and running costs will more than justify their usage.
