Introduction:

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

·The impeller adopts multi-wing structure, which has stronger suction force and higher efficiency.

·The motor adopts aluminum alloy shell, which has the advantages of light weight and good heat dissipation. S1 working system, 24 hours continuous operation. The internal parts of the motor are all high temperature resistant materials, which can withstand high temperature of 300 ℃.

·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.
