Backward Curved Centrifugal Fans

Backward curved impellers give the best efficiency in the high static pressure region, suited to AHU, RTU, CRAH units and the clean side of dust collectors. The third-generation LWBE3G platform uses a bionic blade profile, covering impellers Ø190–710 mm and static pressures up to about 1,800 Pa. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.
