R2E175-AR70-05 ebmpapst 230V 175mm AC Centrifugal Fan

Description

The ebmpapst R2E175-AR70-05 is a high-speed 230 V single-phase AC centrifugal fan featuring a 175 mm backward-curved impeller made of high-strength PA plastic. Powered by the M2E052-CA external rotor motor, this compact unit is engineered for efficient air displacement in high-resistance environments, achieving speeds up to 2950 RPM. Designed for continuous S1 operation, the fan features an improved Class F insulation system and an integrated thermal overload protector for enhanced thermal durability. Its versatile design allows for installation in any position, making it an ideal thermal management solution for electronic cabinet cooling, ventilation in lab equipment, and HVAC applications across a wide temperature range of -25 °C up to 60 °C.
