R2E225-AX52-05 ebmpapst 230V AC Centrifugal Fan

Description

The ebmpapst R2E225-AX52-05 is an AC Centrifugal Fan measuring 225 mm in diameter and operating on 230 VAC. As a dual-frequency unit, its performance varies: at 50 Hz, it achieves a speed of 2700 RPM, drawing 0.51 A for 115 W of power, delivering a maximum airflow of 1015 m³/h and a maximum static pressure of 540 Pa. At 60 Hz, the fan accelerates to 3000 RPM, consuming 165 W at 0.72 A, reaching a maximum airflow of 1120 m³/h and a maximum static pressure of 740 Pa. This backward-curved, single-intake motorized impeller features an IP44 rating and Ball Bearing system, making it suitable for compact, high-pressure cooling in HVAC and industrial ventilation applications.
