Ventilation principle of push pull fan

　　The main function of the push-pull fan is to cool and exhaust, so do you understand its ventilation principle?

　　The push-pull fan exhausts the air outward, which makes the indoor air pressure drop and the indoor air become thinner, forming a negative pressure area. The air flows into the room due to the compensation of the pressure difference. In the practical application of industrial plant, the push-pull fan is installed on one side of the plant, the air inlet is on the other side of the plant, and the air is convective from the air inlet to the push-pull fan. In this process, the doors and windows near the push-pull fan remain closed, forcing air into the workshop from the door and window on the air inlet side. The air in line and orderly flows into the workshop from the air inlet, flows through the workshop, and is discharged from the workshop by the push-pull fan.
