Maico 0080.0657 Diagonal fan EDR 31

For direct installation in pipes. Conveying medium to large air volumes against high resistance. Compact dimensions, low weight and integrated mounting plate facilitate quick installation. The high efficiency reduces operating costs: the purchase price pays for itself after just one year, depending on the operating time. Intake nozzle for low-turbulence air intake. Diagonal impeller with downstream stator. Profiled impeller and stator blades ensure optimal air flow. With diffuser to increase the static pressure. Gap seal between the suction and pressure chamber reduces overflow losses. Meridian flow path prevents turbulence. Protection class IP X4. Exception EDR 45 to EDR 56 IP 54. Thermal class F. AC motor: Electrical connection via external terminal box. Speed control possible using transformers. Thermal overload protection as standard. Depending on the version, the connections of the thermal contacts must be connected to an MVE 10 motor protection switch or the control circuit of a contactor. Electrical connection: mains frequency 50 Hz.
