Centrifugal fan R series

EC motorwith forward-curved bladesflange

R series Product specification: Single-ended/double-ended extracting EC centrifugal fans in the optimised spiral housing with forward-curved blades. Energy-optimised for operation in a spiral housing for a high level of efficiency and favourable acoustic characteristics. Available in frame sizes 180 to 450 mm (single-ended) and 250 to 450 mm (double-ended). This allows for volume flow rates of up to 9,000 m³/h and static pressures of up to 1,100 Pa. Properties & special features: Scroll fans in the R series are characterised by their high output density. The high number of blades means the fans have good sound characteristics with very little noise produced by the blades rotating. Housing with discharge flange and fastening bracket.
