Qingdao ZONGDA Machinery Co., LTD. Ventilation Fan Production factory，It mainly produces mine fans, mining fans, axial flow fans, centrifugal fans, etc. The products are widely used, such as boiler drum, induced draft, workshop, cinema ventilation, textile axial flow, chemical explosion-proof ventilation, gas pressurized ventilation and industrial kiln ventilation; Ventilation of main fan, auxiliary fan, local fan and tunnel in mines such as metallurgy, nonferrous metals, gold, building materials and nuclear industry; Our products can be used for main fan and local fan ventilation in coal mine.

Compared with similar fans at home and abroad, the high-pressure centrifugal fan has the characteristics of high efficiency, low noise, flat performance curve and wide high-efficiency area, which has reached the domestic advanced level. It can replace roots blower with similar performance.

The fan is a three-stage impeller series high-pressure fan, which is generally used for forging furnace and high-pressure forced ventilation, and is widely used for material transportation. It can be used to transport air and non corrosive, unnatural and non viscous gases. The temperature of conveying medium shall not exceed 80 ℃. The dust and hard fine particles contained in the medium shall not be greater than 150mg / m3.
