The push-pull fan is a kind of equipment used in the current project. In the process of using this kind of equipment, the push-pull negative pressure fan is also changing. In today's market, this kind of equipment has reached the high level of automatic control system, which is more convenient to use and less prone to failure. In addition to the advantages of push-pull negative pressure fans, what are the characteristics?

The push-pull fan is a machine that utilizes the cooling principle of air convection and negative pressure ventilation. It is a machine that naturally draws in fresh air in the opposite direction from where it is installed - a door or window, and pushes hot indoor air out of the room faster. Bad ventilation problems can be changed. The cooling air exchange effect is relatively high.

1. A separate centrifugal push-pull mechanism device can automatically open and close the shutter blades. The mechanical centrifugal open mechanism adopts relatively high toughness and increased strength nylon raw material for injection molding, which has high strength and long service time. The steel embedded in the guide rod is installed on the impeller, which increases the durability of the mechanism and reduces the expansion and contraction changes in the nylon production process;

2. The outer frame material is made of thick galvanized steel sheet, which has good corrosion resistance, good manufacturability of CNC machine tools and high precision; the new type of torsion-forming stainless steel fan adopts a faster blade stamping process, which is free of deformation, fracture and beautiful. The blade adopts high-precision dynamic balance verification and correction, running smoothly, without vibration, noise reduction, and increasing service life;

3. The V-belt pulley is made of high-strength aluminum-magnesium alloy hot die casting, which is light in material and high in strength;

4. Equipped with energy-saving and moisture-proof motor, protection grade IP55, insulation grade F; strict quality inspection procedures: noise inspection, vibration inspection, concentric performance inspection, fan speed inspection, overall efficiency inspection.

In fact, push-pull fans are not a fixed program and system. Our consumers can negotiate with the manufacturer before purchasing. The manufacturer will customize the a-belt or b-belt push-pull negative pressure fan according to the customer's own needs, so that consumers can use the equipment to a certain extent after purchasing the product function.
