WD4-72-11 Type Roof centrifugal Fan

 

The utility model WD4-72-11 centrifugal roof ventilator is suitable for ventilation and air exchange in industrial and mining enterprises, civil buildings, environmental protection systems, chemical departments and other departments. It is an ideal equipment for preventing heat and lowering temperature.

 

The fan impeller is calibrated by static and dynamic balance, so it is stable, low noise, flame-retardant FRP material is used in the housing and inlet, it has the characteristics of corrosion resistance and fire resistance, beautiful appearance, light weight, convenient maintenance and so on.

 

The WD4-72-11 type roof fan is divided into 5 units and 5. 5 units. The Y series motor is used in the ventilator. It has the characteristics of large flow rate and high pressure. 5. The fan adopts the outer rotor motor and can be fitted with the three phase contact voltage regulator. Achieve different flow rate and full pressure by changing rotational speed (when using three-phase contact voltage regulator, adjust the voltage regulator pointer to zero first, then adjust to the required speed gradually after starting up, if the fan does not need to change speed, Voltage regulator can be adjusted to a fixed position, speed range 200m 950r / min.

We could Design and Produce the Marine fan,Industrial Fan,and Other Ventilation Equipment according to your detailed requirement !
