1)This fan adopts advanced frontward open system,butterfly type,with two semicircle shutter doors,wind resistance is samall,good air-tightness and high effciency;
2)For the cone part,adopt new design,plug-type connection,not need many bolts and nuts for tightening as before,intensity of labor is reduced,also imporove aesthetic results of fan.
3)The belt rensioner device made of aluminum-magnesium alloy,non-deforming,long service life.This device make the belt inside tight up,effective for avoiding the belt distortions in reverse direction,so prolong the belt life time,saving cost.
4)When the two semicircle shutter doors close,the rubber sealing ring make good air-tightness. In different condition,not run all the fan,the air could pass through the space of stop,use this type fan,could avoid this problem.Ensure air pass through the evaporative cooling pads or air inlet only,so that greatly improve the fan efficiency,(as compared with different type of sane size fan,improve efficency 15-20%);
The fan motor installed on top left corner,effective protection of the motor,Avoid wind resistance.And the motor panel connection is reasonable,fixing fan frame more stronger.
Any needs please feel free to contact with Ms Lisa huang.
