A push-pull fan is mainly composed of a frame, a blind, a protective net, a fan blade, a motor, a support frame and the like. When the motor starts, the fan blades rotate and the blinds open automatically. When the machine is stopped, the blinds are automatically closed to reduce the entry of dust and foreign matter outside the house, and also reduce the effects of rain, snow and wind.

According to the material of the fan frame

Can be divided into FRP fan, galvanized plate fan and plastic steel fan:

FRP fan

Fiber-reinforced plastics combine the hardness and hardness of glass. Acid and alkali resistant, light and stable, long service life (up to 20 years), the price is more expensive than other materials;

Galvanized sheet fan

The main material is galvanized tin (or steel plate), which is a very common fan now, and the price is relatively affordable, but the service life is short (usually 8-10 years);

Plastic steel fan

Frames made of PVC profiles are rarely used on the market due to their fragility.

1. The blade is made of mirror stainless steel stamping, with large air volume, no deformation, no break, no ash, beautiful and easy to use.

2. The push-pull fan shroud is made of thick galvanized layer or stainless steel, which increases the thickness to ensure that it will not rust in the future. It adopts the valgus diversion design to increase the ventilation, reduce the vibration and noise of the fan, and increase the stability of the fan. .

3. The fan blades are corrected by the computer dynamic balance tester to make the fan run smoothly, reduce noise, increase stability and increase service life.

4. The motor adopts aluminum-magnesium alloy casing, which has good heat dissipation, high efficiency, small motor size, light weight, low current and large torque.

Push-pull fan performance characteristics:

1. The blade is made of mirror stainless steel stamping, with large air volume, no deformation, no breakage, no ash, good appearance;

2. The fan shroud adopts galvanized layer of 275 g/square, which increases the thickness of the galvanized layer to ensure that it will not rust in the future; it adopts the valgus backflow design to increase the ventilation, reduce the vibration and noise of the fan, and increase the stability of the fan. ;

3. The motor adopts aluminum-magnesium alloy casing, which has good heat dissipation, high efficiency, small motor size, light weight, low current and large torque.

4, according to customer needs can be installed and installed ring hoisting ring, convenient for customer installation.
