Backward curved blade EC Centrifugal Fan from GP Motor with High Efficiency ,impeller diameter from 133 to 630.

Advantages of EC Centrifugal Fan
1. Can save 1/3 energy than AC equivalent, Save your money.
2. Low motor temperature: for longer lifetime than AC equivalent;
3. 100% speed controllable, not frequency dependence.
4. Can be set-up for constant airflow or constant pressure applications, 0-10VDC or PWM control signal;
5. Electronic & power transformations are completely integrated within the motor.;
6. Speed can be driven up to 3600rpm, one EC fan replace multiple type of motors (2, 4 and 6 pole);
7. Easy connection : No complicated wiring and set-up with a frequency controller.
