Professional Supply Stainless Steel Blower Exhaust Hammer Negative Pressure Fan

Product Description

Negative pressure fan uses the cooling principle of air convection and the negative pressure air exchange, air is discharged to outdoor which makes the indoor air pressure drop, indoor air becomes thinner, forming a negative pressure zone, then outdoor air, due to the air pressure difference compensates into the room, so that the indoor stuffy gas can be quickly forced to discharge outdoor.

By this way,cooling effect can reach 90%-97%.Thus,negative pressure fan has the advantages of less investment, low energy consumption, significant cooling effect, etc.

A galvanized sheet metal negative pressure fan is a common type of negative pressure fan whose housing is usually made of iron or other metal materials. It achieves the effect of ventilation and air exchange by drawing in air and discharging it outside. The galvanized sheet metal negative pressure fan is widely used in ventilation and exhaust in industrial production workshops, agricultural farming, commercial buildings, and other places.
