Push Pull Negative Pressure Fan




Ventilation principle of push pull negative pressure fan
The negative pressure fan exports the air to make the indoor air pressure drop, the indoor air turns thin, the animal husbandry characteristic forms a negative pressure area, the air because of the barometric difference compensates to flow into the room. In the practical application of the industrial workshop, The negative pressure fan is concentrated on the side of the workshop, and the air inlet is on the other side of the workshop. The air flows from the intake port to the negative pressure fan to form a convection blower. During this process, doors and windows close to the negative pressure fan are closed and forced air flows into the workshop by the door and window of the intake port. The air is lined up and orderly from the air inlet into the workshop, flowing through the workshop, and out of the workshop by the negative pressure fan. The ventilation rate is as high as 99%. Through specific engineering design, according to the need to design ventilation rate and wind speed, any high heat, harmful gas, dust, smoke can quickly discharge workshop, any ventilation problems can be solved once and for all. The effect of ventilation can be achieved within a few seconds of starting the fan.



advantage
※A set of ventilation, ventilation, cooling in one.
