Description
The ebmpapst R1G175-RB33-10 is a high-power DC Centrifugal Fan with an impeller size of 175 mm and dimensions of 175 x 68 mm. Driven by the high-performance M1G055-BI external rotor motor, this backward-curved fan is a key model in the aerodynamically optimized RadiCal series. Operating on a nominal 48 VDC with a wide input range of 36-60 VDC, it features a robust power input of 76 W and an output of 62 W. At its maximum speed of 3950 RPM, it delivers a massive airflow of 341.4 CFM (580 m³/h). Specifically engineered as an energy-saving ventilation solution for high-density Fan Filter Units (FFU) and telecommunications infrastructure, it features a glass-fiber reinforced PA plastic impeller designed to maximize static pressure efficiency. With integrated 0-10V or PWM speed control, IP54 protection, and a four-wire termination system, it provides superior reliability and precise airflow management for mission-critical industrial and medical cooling applications.
