R1G175-AB41-02 ebmpapst 48V0.8A37/25W centrifugal fan

Description

The ebmpapst R1G175-AB41-02 is a high-performance 175 mm EC Centrifugal Fan (Backward Curved Motorized Impeller) designed for high-efficiency DC operation. It runs on a nominal voltage of 48 VDC (36 VDC to 57 VDC range). The fan achieves a nominal speed of 3100 RPM, with a maximum power consumption of 34 W and a current draw of 0.8 A. It delivers a maximum air flow of 560 m³/h (equivalent to 330 CFM) and operates with a noise level of 65 dBA. Constructed with a durable fiberglass-reinforced PA plastic impeller and using robust Ball Bearings, this unit offers comprehensive electronic protection (reverse polarity, locked-rotor) and precise speed control via 0-10 VDC / PWM input, making it highly suitable for integration into smart ventilation and air filtration units.
