R1G175-AB41-64 ebmpapst 48V DC Centrifugal Fan

Description

The ebmpapst R1G175-AB41-64 is a compact, high-efficiency EC Centrifugal Fan with backward-curved blades, measuring approximately 175 mm in diameter. It operates on 48 V DC and is powered by a GreenTech EC motor, offering a nominal speed of 3100 RPM with a power input of 34 W and a current draw of 0.8 A. This fan delivers a high unimpeded airflow of approximately 560.7 m³/h (330 CFM) and features integrated electronics with PWM control and a speed sensor (Tach output). With a wide operating temperature range from −25 °C to 60 °C and a ball bearing system, this unit is engineered for reliable, continuous operation in telecommunication cabinets, air purification units, and industrial cooling applications where space and energy efficiency are critical.
