negative pressure fan:
negative pressure fan is a common cooling device used in the workshop. It is a machine that uses air convection and negative pressure ventilation to cool down, and naturally sucks fresh air from the opposite side of the installation site-the door or window, and quickly forcibly discharges the indoor sultry gas to the outside. Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90%-ninety-seven percent.
