The R1G220-RD10-81 from EBM Papst is a high-performance EC centrifugal fan with backward curved blades and single inlet, designed for demanding railway environments. The fan delivers up to 1,070 m³/h at 0 Pa and is driven by a 24 VDC motor (range 16 – 32 VDC) with a low power consumption of 125 W. It has protection against overcurrent, overtemperature and reverse polarity, and is controlled via 0–10 V or PWM signal. The robust construction in cast aluminum and plastic with IP24 protection and ball bearings ensures a long service life even under vibrations and varying temperatures between –25 and +60 °C.
