Acoustic Cabinet Fans

Range of in-line cabinet fans, manufactured from galvanised steel sheet with double thickness side panels internally lined with 17mm thickness of fireproof fibreglass acoustic insulation (M0).

All models incorporate backward curved centrifugal impellers, are dynamically balanced and supplied with circular duct connection flanges and remote terminal box.

Available, depending upon the model, with single phase or three phase motors in 4 or 6 poles.

All the motors are IP55, Class F (1) insulation, with thermal protection (2).
Electrical Supply:
Single phase 230V-50Hz.
Three phase 230/400V-50Hz

Three phase motors are speed controllable by an inverter.

(1) Air stream temperature limits -40oC to +70oC.
Models /4-9000 and /6-6000to /6-17000 suitable for usage in environments up to +40oC.
(2) Except models 6000 to 17000.

Industrial Extractor Fan FAQs

What is an industrial exhaust fan?

An industrial exhaust fan is designed to provide a large flow of air (or another type of gas) to a specific part of a building. The fan is usually comprised of a number of rotating blades connected to a shaft, which is powered by a motor.

Do extractor fans need to vent outside?

Extractor or exhaust fans typically need to vent outside, as opposed to recirculating the air back through the space.

How long should an extractor fan stay on for?

An extractor fan should stay on as long as it’s needed to extract the contaminated air in a particular space.

Do industrial extractor fans use a lot of electricity?

Industrial extractor fans will naturally use more energy than domestic extractor fans, the amount of electricity will directly relate to the number of watts that your fan operates at, how long you use it for and any environmental conditions that might affect its performance.

What type of extractor fan do I need?

The type of extractor fan that you’ll need will depend on your circumstances. For example, some extractor fans are designed to deal with dust or chemicals, whilst others may be designed to fit into roof spaces or connect to a vent system.

How do I know what size extractor fan I need?

The right size extractor fan for your needs will meet the performance requirements of your space, sometimes measured in m3/hours. Generally speaking, larger spaces will require higher performance extractor fans to properly exhaust the air, these will tend to be larger in size.
