Negative pressure fan is a cooling principle that utilizes air convection and negative pressure ventilation,suction fan It is a machine that naturally sucks in fresh air from the opposite side of the installation location - the door or window, and quickly forces the indoor hot and humid gases out of the room. The problem of poor ventilation can be improved, and the cooling and ventilation effect can reach 90% -97%.
The whole machine adopts CAD/CAM design, which has the characteristics of low investment cost, large air volume, low noise, low energy consumption, stable operation, long service life, high efficiency, etc. The louvers automatically open and close to achieve dust and water resistance, and are beautiful and elegant; It can be used for both blowing and drawing air, making it a choice for cooling and ventilation in modern workshops. Environmentally friendly and energy-saving negative pressure fans will become the mainstream of the ventilation and cooling equipment market.
1. Used for ventilation and air exchange: installed outside the workshop window, usually selecting a lower air outlet to draw air outward and extract odorous gases; There are many applications such as general negative pressure fan factories.
2. Used in conjunction with wet curtains: Used for workshop cooling in hot summer, no matter how hot your workshop is, the wet curtain negative pressure fan system can lower the temperature of your workshop to around 30 ° C and provide a certain level of humidity.
