With the help of CFD (Computational Fluid Dynamics) the newly developed, high performance centrifugal impeller, the E-Series “REVOLUTION“, complements the existing range of Rosenberg free-running impellers by introducing a line specifically designed for volume flow. Contrary to the pressure focus of the B-Series, manufactured from aluminium, this impeller series is designed and manufactured especially for the use of larger volume flow and lower pressure. The impellers are manufactured using a black, UV-stabilised, glass-fibre reinforced polypropylene.
When used with an Electronically Commutated Motor (EC-Motor) or an AC-External Rotor Motor, Rosenberg centrifugal fans with reduced noise, free-running, backward curved, high performance impellers make a very compact, efficient and optimally designed fan unit. The fan units are available as Motorised Impeller or Fan Module (Plug Type) in sizes 315 – 560 mm wheel diameter.
