The push-pull fan is a kind of machinery that relies on the input mechanical energy to increase the gas pressure to discharge the gas. It is a driven fluid machinery.

The push-pull fan is mainly composed of fan blades, motor, outer frame, protective net, support frame, shutters and other components. The motor drives the fan blades to generate air flow. The type of movable shutters can be equipped according to user needs. Closed to prevent the entry of outdoor dust, foreign objects, etc., and also to avoid the influence of rain, snow and downwind.

Features of push-pull fan:

1. The outer frame material is made of extra-thick galvanized sheet with strong corrosion resistance;

2. The outer frame is made of CNC machine tools, with excellent craftsmanship;

3. There are two types of high-strength aluminum alloy cast steel wheel hubs: new twisted stamping and forming fan blades;

4. Reasonable blade angle can make the air flow reach a good level;

5. The high-precision microcomputer-aided manufacturing system can make the fan work efficiently; strict quality inspection procedures: noise inspection, vibration inspection, concentric performance inspection, fan blade speed inspection, complete machine efficiency inspection: high-performance 380V three-proof special motor;

6. Iron air collector and glass fiber reinforced plastic air collector (two types) are used: the rear safety net is easy to disassemble, and CAD is optimized for design.
