Julai (Chongqing) ventilation equipment Co.,Ltd
Negative Pressure Fan is a cooling principle that utilizes air convection and negative pressure ventilation. It is a machine that naturally sucks in fresh air from the opposite direction of the installation site - the door or window - to quickly force the indoor hot gas out of the room. Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90% -97%.
