Ecofit / EC Fans

Return
The ECOFIT EC motor is a synchronous motor designed to be powered by 230V 50/60Hz (115V is optional with special adapter). Unlike AC asynchronous motor, the EC motor has no slippage, thus less losses and a higher efficiency.
Compared to standard AC fans, EC fans rotational speed is not limited by power supply frequency but only by the maximum motor power.
EC fans are easy to control with a 0-10VDC voltage or PWM signal. A 10VDC output is integrated inside the electronic for fan control.

ECOFIT has extended range of backward curved fans, double inlet and single inlet centrifugal blowers with the combination of a new EC technology motor.

Available in 192, 220 and 225, 250, 280 and 315mm diameter impellers, these fans offer higher efficiency thanks to the EC motor. These motorized impellers are well adapted for free air operation but can also be installed in circular, rectangular or scroll shaped housings. Airflow range varies between 390 CFM to 1475 CFM.

EC technology is also available for forward curved centrifugal fans: single inlet diameter 140 mm, 160 mm and double inlet diameter 146 mm, 160 mm. The forward curved centrifugal blower’s main advantage is “constant pressure” or “constant airflow” control without sensor.

The ECOFIT DC range consists of backward curved fans, axial fans and available in 24VDC or 48VDC.

Main characteristics are:
- Nominal voltage: 24VDC (18-36VDC); 48VDC (36-60VDC)
- Reverse polarity protection
- Soft start
- Locked rotor protection
- Tach. output (open collector)
- Controlled 0-10VDC signal (potentiometer) or PWM
- IP44
