Overview

YWF External Rotor Axial blower Fan is a new product developed by our company by combining technology and talent advantages of many domestic colleges through repeated research and trail production. The impeller is directly fixed on the excircle to make axial size smaller. Its successful development is a key breakthrough of axial flow fan and achieves internationally advanced level.

This blower fan is featured by high efficiency, whole sealing, low noise and vibration, short axial size and maintenance prevention, so it has wider applicable fields, can replace the conventional axial flow fan, and also can be used for kitchens, industrial and mining factories and other places with serious oil, soot and dust.

Operating Environment: Elevation: below 4,000m, air humidity: less than 90ºC and ambient temperature: -25ºC~+60ºC for general products, products used in unconventional environment also can be customized.

Competitive Advantage of external rotor

Structure of blower fan : The new outer rotor fan’s impeller is mounted directly on a rotating outer rotor’s excircle , impeller rotates together with the external rotor motor, motor’s main shaft is stationary.

Stability of blower fan : impeller and external rotor are fasten to the outer rotor’s excircle by soldering or press fitting to form a whole. No secondary assembly errors, greater reliability and stability, less vibration.

Performance of blower fan : more energy efficient, the national energy efficient products.

Noise of blower fan : impellers after aerodynamic design again to ensure that the premise of wind capacity, lower noise, high efficiency, energy saving effect is more obvious.

Cooling of blower fan : The motor is mounted in the middle of the fan impeller, better thermal performance, The motor itself has reached the maximum cooling effect and longer life.

Shape and weight of blower fan : whole elegant appearance, elaborate design, the fan’s axial length is much shorter, compact structure, saving installation space, the installation more convenient and flexible. Due to optimize the product structure design, small size, lighter weight.
