Working Principle Of Negative Pressure Fan

The negative pressure fan exhausts air outward, causing a decrease in indoor air pressure. The indoor air becomes thinner, forming a negative pressure zone, and the air flows into the room due to pressure difference compensation. In practical applications in industrial factories, negative pressure fans are installed centrally on one side of the factory building, with the air inlet on the other side of the factory building. The air flows from the air inlet to the negative pressure fan to form convective blowing.

Thorough and efficient ventilation, with a ventilation rate of up to 99%. Through specific engineering design, designing air exchange rates and wind speeds as needed, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problem can be completely solved at once. The ventilation effect can be achieved within a few seconds of turning on the fan.
