Application

Transport of dusty air.

Construction

Medium-pressure centrifugal fans with direct drive or belt drive.

MRB fans' impeller with backward curved straight blades, profiled, welded from steel sheet or aluminum sheet dynamically balanced as per ISO 1940.

Housing made of welded steel sheet. Fans come standard in LG 270 configuration. Fans in other configurations are available on customer's request.

Electric motor
