1． Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements
2． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and easy to abstract heat., thus ensure to maximum the reliability of fan operation,
Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system
