Duct fan EDR series

diagonalextraction230VAC

• For direct installation in ducts. • Displacement of medium to large air volumes against high levels of resistance. • Compact dimensions, low weight and integrated installation plate simplify fast installation. • High efficiency reduces operating costs: Depending on level of use, purchase price is amortised after just one year. • Suction nozzle for turbulence-reduced air intake. • Diagonal impeller with downstream stator. • Profiled impeller and stator blades ensure optimum flow. • With diffuser to increase static pressure. • Gap sealing between intake and pressure chamber reduces overflow losses. • Meridian flow course prevents turbulence. • IP X4 degree of protection. Exception EDR 45 to EDR 56 IP 54. • Insulation class F. • Electrical connection via external terminal box. • Speed can be controlled using transformers. • Thermal overload protection as a standard feature. • Depending on versions, thermal contacts must be connected to an MVE 10 full motor protection switch or the control circuit of a contactor.
