🔗 CABINET CENTRIFUGAL FANS

Characteristics

• An extractor fan offers a relatively constant air volume even when the duct resistance(static pressure) is changed. 

• Efficient and noiseless in a region of high static pressure. 

• Can be used between spiral ducts like inline fans. 

Usages 

• Exhaust and supply the air to the building, apartments, factory, warehouse, etc.

• Used for air conditioning.
