R2E225-BD92-37 ebmpapst 230V 225mm AC Centrifugal Fan

Description

The ebmpapst R2E225-BD92-37 is a robust 230 V single-phase AC centrifugal fan featuring a 225 mm backward-curved impeller precision-engineered from galvanized sheet steel. Driven by the high-torque M2E068-DF external rotor motor, this unit is designed for heavy-duty air displacement in high-resistance environments, maintaining balanced airflow at speeds up to 2700 RPM. Engineered for maintenance-free S1 continuous operation, it features a specialized motor design with a thermal overload protector and premium ball bearings to ensure longevity. This fan is an ideal thermal management solution for industrial ventilation, server rack cooling, and cleanroom technology, providing reliable performance across a wide ambient temperature range of -25 °C to 55 °C.
