Outdoor centrifugal fan for 48 V systems

The 175 mm diameter impeller runs at 2600 r/min and delivers up to 35000 m³/h airflow. It is built for machinery and ventilation projects that require a compact external-rotor motor operating from a 48 V supply.

Steel housing with external rotor motor

Sturdy steel plate construction protects the motor while the external rotor design provides forced electronic cooling and a compact footprint. The fan supports 100 % speed control via analog or serial interface for simple integration into existing control cabinets.

Dual power rating 76 W / 62 W at low current

Motor power is rated at 55 W with a current draw of 0.5 A, keeping heat and noise low during continuous operation. The GreenTech EC technology enables efficient performance without a separate scroll housing, reducing installation complexity.

Questions about this item

What voltage does the 48V centrifugal fan actually require?

The motor is rated for 115 V AC input and draws 0.5 A at that supply.

What mounting clearance does the 175 mm blade diameter need?

The impeller measures 175 mm across, so allow at least that diameter plus housing depth for free-air intake.

How do I wire the external-rotor motor for speed control?

Connect the supply to the motor terminals; the 100 % speed-control range works via an analog or serial interface on the GreenTech EC electronics.
