CEM – BLR Centrifugal Radial Fans


Attention: the orientation of the blower must be stated when ordering

High-efficiency electric BLR Centrifugal Radial Fans (sometimes called blowers) suitable to deliver very high quantities of clean or slightly dusty air with temperatures of up to 60° C. These fan types are widely used on board for suction and ventilation of air in closed environments such as WC, kitchens, galleys, engine rooms

Radial blowers have wheels whose blades extend straight out from the centre of the hub. Radial blowers are far more sucessful in extraction that their cousins the curved bladed centrifugal blowers such as the CEM BLC Blowers, however they can be associated with higher noise in operation. High speeds, low volumes, and high pressures are common with radial blowers and are often used in vacuum cleaners, pneumatic material conveying systems, and similar extraction processes
