Centrifugal Fans

Clean Air’s high-quality, competitively priced plastic centrifugal fan ranges complement our comprehensive selection of fume cupboards. Manufactured from polypropylene and/or PVC, the fans are designed to resist the widest range of corrosive chemical fumes at temperatures up to 40°C.

The systems are fabricated in our Manchester-based factory by a highly skilled team of plastic fabricators and CNC machine operatives, and are individually engineered for optimum efficiency, reduced noise levels and energy conservation. 

Clean Air Centrifugal Fan Ranges

The centrifugal fan ranges are available in a choice of rotation and discharge angles and include bifurcated inline fans. Our plastic centrifugal fans are capable of handling air volumes up to 25 m³/s and pressures up to 2200 Pa.

With seven different ranges and up to 13 different sizes, we can supply the appropriate plastic extract fan for most applications.
