Fans R4E310-AP11-09/F01Motor 230V 115W centrifugal blower
A 230 V centrifugal blower with a 310 mm backward-curved impeller delivering up to 35000 m³/h for air purification and charging-pile cooling
- Centrifugal airflow up to 35000 m³/h for air purification systems
- Backward-curved impeller with 6 blades runs at 1390 r/min for quiet operation
- External rotor motor design gives compact build and forced electronic cooling
- 100 % speed control via analog or serial interface for precise adjustment
- Operates reliably from -25 °C to 65 °C ambient temperature
Product identity
This is a new ebm-papst backward-curved centrifugal blower rated for 230 V AC and 115 W motor power. It is built for air-purification systems and charging-pile installations that need a compact, scroll-housing-free fan.
Critical specification
The impeller diameter is 310 mm and the motor runs at 1390 r/min while drawing 0.52 A at 230 V. Matching these voltage, current and speed figures to the original equipment drawing is the single check that confirms fit.
Sustained-load behaviour
The external-rotor motor places the windings inside the airflow, giving continuous cooling across the full -25 °C to 65 °C ambient range. Speed remains controllable from 0 to 100 % via analogue or serial interface without thermal derating during extended operation.
Highlights
- Centrifugal airflow up to 35000 m³/h for air purification systems

- External rotor motor design gives compact build and forced electronic cooling
- 100 % speed control via analog or serial interface for precise adjustment
- Operates reliably from -25 °C to 65 °C ambient temperature

Questions about this item
How much airflow will the 115 W motor actually deliver inside a unit?
The backward-curved impeller can move up to 35000 m³/h at 1390 rpm when mounted without a scroll housing.
What does the 230 V AC supply limit in terms of speed control?
The external-rotor motor accepts 0–100 % analogue or serial speed control directly from the 230 V line.
Will the 310 mm blade diameter fit a standard 310 mm fan tray cut-out?
The 310 mm impeller is designed as a free-wheeling backward-curved fan, so it needs only the impeller clearance, not a full scroll housing.
