SKU CH-2KGX-HKECY MPN R1G175-RB33-G01Voltage

175 mm centrifugal fan delivers up to 35000 m³/h airflow at 3950 r/min with 48 V PWM speed control

  • High airflow up to 35000 m³/h for demanding cooling
  • 48 V EC motor with 36–60 V range enables precise speed control
  • 175 mm backward-curved impeller runs at 3950 r/min for strong pressure
  • External rotor design integrates motor in impeller for compact, efficient cooling
  • Four-wire PWM interface allows 100 % analogue or serial speed regulation

Industrial Cooling Fan

The 175mm centrifugal fan operates on a 48V supply with a 36-60V range and delivers up to 35000m3/h airflow. It draws 1.90A at 76/62W and spins at 3950r/min for demanding thermal management. The four-wire interface enables 100% speed control via analog or serial connection.

Sustained Operation

External rotor motor design provides forced electronic cooling during continuous duty cycles. Sturdy steel plate construction resists vibration at 3950r/min without performance degradation. GreenTech EC technology maintains efficiency across the 36-60V input range under prolonged load.

Build and Integration

Compact external rotor motor allows installation in space-constrained industrial enclosures. Waterproof rating supports deployment in harsh environments requiring moisture resistance. Free-wheeling backward-curved blade design eliminates need for separate scroll housing.

Domande su questo articolo

How loud and hot does the 175 mm 48 V centrifugal fan run at 3950 r/min all day?

The fan draws 1.90 A and 76/62 W at 3950 r/min; its external-rotor motor design provides forced electronic cooling for continuous operation.

What power source and control connection must I already have for this 4-wire 48 V fan?

You need a 36-60 V DC supply capable of 1.90 A and a 4-wire PWM or 0-10 V control interface for 100 % speed control.

Will this 175 mm ebm-papst turbine fit the same mounting holes as my older 175 mm case fan?

The compact external-rotor motor and steel-plate housing match standard 175 mm diameters, so existing mounting points align.
