Feature

1.A new product developed by our company by combining technology and talent advantages of many domestic colleges through repeated research and trail production.

2.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.

3.Advntage: 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.

4.Usage: kitchens, industrial and mining factories and other places with serious oil, soot and dust.

Model Description

Advantage of the external rotor

Structure: 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: 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: more energy efficient, the national energy efficient products.

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

Cooling: 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: 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.
