Designed for Automation, the ebm-papst R2E175-AC91-05 AC centrifugal fan provides a defined platform for controlled heat removal and airflow management. It suits OEM equipment and service replacement when checked against the exact drawing and operating curve.
Documented selection points include 400 V supply, 65 W input, 175 mm size, 2550 rpm speed. These values support electrical, envelope and duty-point comparison.
For procurement, verify voltage, duty point, dimensions, connector and mounting. Correct sizing and clear airflow paths support stable operation, controlled noise and long service life. Confirm speed control, IP protection and approvals in the exact-model datasheet. The listed ratings help buyers screen compatibility before final duty-point review.
The ebm-papst R2E175-AC91-05 from the EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including R2D, R4E. Key benefits:
R2E EC fans operate at V with W rated power. When replacing AC models, wire the 0-10V control signal alongside the standard three-phase power cable.
