R2E180-AS77-05 ebmpapst 230V 180mm AC Centrifugal Fan

Description

The ebmpapst R2E180-AS77-05 is a specialized 230 V single-phase AC centrifugal fan featuring a 180 mm backward-curved impeller made of high-grade black PA plastic. Powered by the M2E068-BF external rotor motor, this unit is designed for efficient air displacement in high-pressure systems, delivering a steady speed of 2300 RPM. Engineered for S1 continuous operation, it includes an integrated thermal overload protector and maintenance-free ball bearings to ensure long-term reliability. This compact fan is an ideal thermal management solution for electronic cabinet cooling, ventilation in laboratory equipment, and small-scale HVAC applications, operating effectively within a defined ambient temperature range of -25 °C up to 40 °C.
