What is negative pressure fan?

The negative Pressure Ventilation Fan is made with the negative pressure principle. The Exhaust Fan pulls indoor air out, lowering the air pressure and allowing fresh air from outside to come inside through air vents. This quickly removes heat, odors, or pollution and improves the indoor environment.

Work Principle of FRP Fan Ventilation through Negative Pressure

The FRP fan forces the hot air in the pig barn outside,so the indoor pressure is lowered,forming an negative-pressure zone,and theoutdoor fresh air flows into the pig house for the air pressure difference.Negative pressure causes the air exchange between indoorand outdoor to complete supporting good air quality which not only improves pig health,performance and welfare but also reducesemission of greenhouse gases,odours and dust to the environment,and creating the proper temperature at which pigs feelcomfortable in hot days.

At the sane time,the FRP fan can be also used with evaporative cooling pads to realize an optimum ventilating-cooling effect.
