R2E225-BE51-13 ebmpapst 115V 225mm AC Centrifugal Fan

Description

The ebmpapst R2E225-BE51-13 is a high-capacity AC centrifugal motorized impeller featuring a 7-blade backward-curved design, optimized for high-efficiency air delivery in HVAC and industrial cooling systems. Powered by the M2E068-EC external rotor motor, this unit operates on a single-phase 115 VAC supply at 60 Hz, reaching a nominal speed of 3000 RPM with an input power of 215 W. Constructed from glass-fiber reinforced PA6 plastic, the 225 mm impeller is engineered for any installation position and features an IP44 degree of protection. With an integrated thermal overload protector and dual ball bearings, the R2E225-BE51-13 provides a robust, Class I protection thermal solution capable of continuous S1 mode operation in environments from -25 °C to 55 °C.
