- Full speed control via analog or serial interface
- Wide 36–57 V DC input range suits variable supplies
Industrial Centrifugal Air Mover
The ebm-papst R2E220-AB08-12 is a backward-curved centrifugal fan built for equipment enclosures that demand high static pressure. It suits system integrators and maintenance teams who need reliable forced-air cooling in industrial cabinets, telecom shelters or server racks.
35000 m³/h Peak Flow With 100 W Draw
At 48 VDC nominal (36–57 VDC range) the motor spins at 3100 rpm, delivering up to 35000 m³/h while drawing 2.4 A and 100 W. The steel housing and external-rotor design handle continuous operation from -25 °C to 60 °C, but airflow drops sharply once static pressure exceeds the blade curve’s knee.
48 VDC Bus And Analogue Speed Control
Speed is regulated through a 0–10 V or PWM signal on the motor’s control leads; no separate driver board is required. The fan lacks a tach output and a 12 VDC start-up winding, so it cannot be managed by standard motherboard headers or 3-pin/4-pin fan controllers.

Questions about this item
Will the 115 V centrifugal fan run on my existing 48 VDC power supply?
The motor is rated for 48 VDC nominal with an operating range of 36 to 57 VDC, so it will not operate directly from 115 VAC without a suitable power supply.
How can I confirm the fan is spinning at the rated speed after installation?
The fan should reach 3100 rpm at nominal voltage; you can verify this with a tachometer or motherboard fan-speed readout.
Does the package include a power cable or mounting screws?
The supplier data lists only the centrifugal fan unit itself; cables, connectors and mounting hardware are not included.
