The negative pressure fan is a machine that uses the cooling principle of air convection and negative pressure ventilation. It is a machine in which fresh air is naturally inhaled from the opposite side of the installation site-the door or window, and the indoor muggy gas is quickly forced to be discharged outdoors, and the poor ventilation problems can be improved. The cooling and ventilation effect can reach 90%. 97%.
