Negative pressure fan is a machine that uses the cooling principle of air convection and negative pressure ventilation. It is a machine that naturally inhales fresh air from the opposite direction of the installation site — the gate or window, and quickly forces the indoor hot gas out of the room. Any poor ventilation problem can be improved. The cooling and ventilation effect can reach 90% – 97%.
