Description
ebmpapst K2E250-RA50-15 is a 250 mm diameter centrifugal fan operating at 230 V AC with a power consumption of 125 W and a nominal speed of 2500 RPM. The unit features a backward-curved impeller constructed from glass-fiber reinforced PA plastic and is driven by an M2E068-DF external rotor motor. It incorporates a maintenance-free dual ball bearing system and an internal thermal overload protector (TOP) for operational safety. The assembly is rated for insulation class F and IP 44 protection, utilizing a 5 µF capacitor for single-phase operation. The mechanical design includes 11 blades and allows for any mounting position with integrated condensate drainage holes on the rotor side.
