Working principle of negative pressure fan

Negative pressure is to make air convection in the workshop, but it needs a process of energy conversion. The negative pressure horn fan is driven by electric energy and converted into kinetic energy. The indoor air is discharged from the outdoor to reduce the indoor pressure. Under the action of atmospheric pressure, the outdoor fresh air is supplied from the opposite window and gate where the negative pressure horn fan is installed, resulting in air convection negative pressure.

The bad sources of working environment -- solar radiation, mechanical heat source, workshop structure, odor and lampblack in the intensive production process of Zhigong. The negative pressure type horn fan can exhaust the indoor air out of the outdoor, so as to create a fresh and natural working environment.
