SKU CH-TFGE-DW2MQ MPN R2E225-AX52-05Motor

Centrifugal case fan with 225 mm blade diameter, 230 V supply, 115/165 W power and IP44 protection

  • Centrifugal airflow up to 35000 m³/h for powerful cooling
  • 225 mm blade diameter moves high air volumes efficiently
  • 230 V AC operation at 115/165 W suits industrial power supplies
  • IP44 rated protection resists dust and water splashes
  • External rotor motor design ensures compact build and motor cooling

Industrial Centrifugal Fan 225mm 230V

This AC centrifugal fan from ebm-papst delivers airflow up to 35000m³/h using a 225mm impeller. It operates on 230V mains power with a current draw of 0.51-0.72A and offers dual power ratings of 115/165W. The external rotor motor design ensures compact integration and forced motor cooling. Speed ranges from 2700 to 3000 RPM with IP44 protection.

Suited for Inverter and Cabinet Cooling

Engineers specifying cooling for frequency inverters, control cabinets or industrial enclosures will match the 230V AC supply and high static pressure capability. The IP44 rating handles dust and splashing water in protected environments. Buyers needing low-voltage DC operation, PWM speed signalling or residential noise levels should consider alternative fan types. The 100% analog or serial speed control suits regulated industrial drives.

High Airflow Headroom at Fixed Speed

The 35000m³/h maximum airflow provides substantial capacity for dense heat loads in large enclosures. At 165W peak power the motor sustains continuous duty across the 2700-3000 RPM range. Headroom diminishes when system static pressure exceeds the fan curve knee or when voltage sags below nominal 230V. The compact external rotor layout leaves no space for additional filtration or ducting accessories.

Questions about this item

What power supply and voltage must my system provide for the 230 V, 115/165 W motor?

The fan requires a 230 V AC supply capable of delivering 115 to 165 W, drawing 0.51 to 0.72 A at the rated 2700-3000 rpm speed.

Does the centrifugal impeller need a scroll housing when mounted next to legacy axial fans?

This backward-curved centrifugal fan is designed as a free-wheeling unit and does not require a scroll housing, so it can operate alongside existing axial fans without one.

How can I confirm the IP44-rated unit is running at the specified 2700-3000 rpm after installation?

Measure the motor current; a reading between 0.51 A and 0.72 A at 230 V indicates the fan is operating within its rated 2700-3000 rpm range.
