Introduction:

·The surface of the casing is treated by plastic spraying process, which has the characteristics of environmental protection, temperature resistance and stronger adhesion;

·Impeller adopts multi-wing structure, which has stronger suction force and higher efficiency;

·Motor adopts aluminum alloy shell, which has the advantages of light weight and good heat dissipation.100% copper wire, 

  S1 working system, 24 hours continuous operation, temperature resistant of 130℃;

·Fluorine-rubber oil seal is installed at the end of the bearing, which can prevent dirt and other impurities from entering the bearing. In addition, it can also limit the leakage of lubricating oil in the bearing and    prolong the service life of the bearing.

  Variable-frequency Drive(20HZ-50HZ) can be select, adjust the air volume and pressure of the fan by adjusting the frequency of the motor and changing the speed of the motor.
