The working principle of the negative pressure fan is to exhaust the indoor hot air and odor completely outdoors through the negative pressure, and the fresh air naturally flows into the indoor ventilation. Negative-pressure fan has the characteristics of large air volume, low energy consumption, low speed, low noise, dust and rain proof, and is loved by customers.
Use of negative pressure fan
1. For air extraction and ventilation: Installed outside the window of the workshop, the lower air outlet and outward air extraction are generally selected to extract odorous gases; general factories and other applications are more.
2. Cooperate with the use of wet curtain: Used for cooling workshop in hot summer, no matter how hot your workshop is, the water curtain negative pressure fan system can make the temperature of your workshop drop to about 30C, and has a certain humidity.
3. Used as exhaust fan: At present, the efficiency of general exhaust fan (commonly known as grain fan) is relatively poor, one exhaust fan can blow less than a few people, but negative pressure fan is not, whether on the ground or hanging in the air. Generally, 4 units are used in 1,000 square meters workshop, that is, the room is full of wind effect.
