JW-Cowshed Fan-Negative Pressure Blower-Shandong Jianwei Agricultural Machinery Co., Ltd.

Product description

275g/㎡ zinc coating is used for the fan fairing, which increases its thickness and ensures no rusting in future use. The design of inverting side-flow is used to increase ventilation, reduce the vibration and noise of the fan and increase its stability. The Fan Blades are calibrated by the advanced computer dynamic balance Tester to make the fan run smoothly, reduce noise, enhance stablity and prolong service life. The Motor is made of aluminum-magnesium alloy with good heat dissipation, high efficiency , small ize, light weight,low current and large torque.
