DYMACHINE Industrial Variable Frequency Motor Axial Fan Negative Pressure Fan

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 (gate or window), quickly forcing hot indoor gases out of the room.
Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90% -97%.
