EC fans are actually a complete fan/motor assembly which includes a highly engineered fan and bell mouth matched to an Electronically Commutated (EC) motor. The EC motor is a brushless DC motor with on-board programmable speed control. The EC Fan feature can be selected as an option in Colmac A+PRO software.

Benefits

• High efficiency especially at part load/reduced speed

• Large airflow capacities (up to 910mm diameter)

• Extremely low sound levels

• Long air throw with standard built-in straightening vanes

• Plug-and-play fan/motor/bell mouth assembly

• High reliability and long life

• Corrosion resistant construction

• Ingress Protection rating of IP55

EC fan is a new technology in those years, EC fan has the advantages of AC fan and DC fan, which is EC fan can convert AC power input to DC power output by the way of electronic rectification, to meet the goal of energy saving. It also means, the longer EC fan uses, the more energy it saves. Also, EC fan will not be limited by frequency as AC fan does, it allows EC fan to perform with higher RPM but with less power consumption. And EC fan motor design is similar with DC motor, so, the motor will be with less consumption of the ball bearing, and with better life expectancy than AC fan.

EC fan feature

1. More than 50% energy saving than AC fan

2. Better RPM performance with less limitation than AC Fan

3. Customized speed control Design

4. Better Life Expectancy than AC fan

5. Less temperature rising than AC fan
