R1G225-AF07-52 ebmpapst 24V 225mm EC Centrifugal Fan

Description

The ebmpapst R1G225-AF07-52 is a high-performance 24 VDC GreenTech EC centrifugal fan featuring a 225 mm backward-curved RadiCal impeller made of glass-fiber reinforced PA66 plastic. Driven by a compact M1G074-BF motor, this unit is engineered for precision air displacement in low-voltage applications, delivering a speed of 2600 RPM with a power consumption of 100 W. Designed for S1 continuous operation, it integrates advanced technical features including a 0-10 VDC/PWM control input, tachometer output for speed monitoring, and comprehensive reverse polarity and soft start protection. This SELV-compliant air-moving solution is ideal for telecommunications, industrial control cabinets, and battery-powered ventilation systems, maintaining high reliability and EMC industrial immunity across an ambient temperature range of -25 °C to 60 °C.
