RRE & RRM Backward Curved Centrifugal Fans
Available with AC or EC External Rotor Motors
We offer high efficiency RRE & RRM backward curved centrifugal impellers, manufactured from either plastic reaction or galvanised sheet steel. Where necessary they can be installed in circular, rectangular, or scroll-shaped housings providing there is sufficient clearance to the side wall. RRE & RRM Ecofit fans provide airflows from 315 to 3300m3/h and a maximum pressure from 100 to 700Pa. Contact us with your requirements, we’ll quickly provide the best fan solution for your application.
