K2E225-RA92-09 ebmpapst 230V 225mm AC Centrifugal Fan

Description

The ebmpapst K2E225-RA92-09 is a high-performance 225 mm AC centrifugal fan assembly featuring a sophisticated backward-curved design integrated with a protective housing and guard grille. Powered by the M2E068-DF external rotor motor, this unit is optimized for 230 VAC single-phase operation, requiring a 3.5 µF capacitor to achieve a peak power consumption of up to 225 W at 60 Hz. The 7-blade impeller, housing, and guard grille are all constructed from durable glass-fiber reinforced PA plastic, providing a lightweight yet robust airflow solution with an IP44 protection rating. With a static efficiency of 42.5% and conforming to ErP N62 efficiency grades, it delivers precise performance for demanding ventilation tasks. The motor features a black-painted rotor surface, Class F insulation, and an internally connected thermal overload protector, ensuring reliable S1 continuous duty in air conditioning and industrial cooling systems across ambient temperatures up to 70 °C.
