The entire negative pressure fan is designed using CAD/CAM, featuring low investment cost, large air volume, low noise, low energy consumption, stable operation, long service life, and high efficiency. The shutter automatically opens and closes to achieve dustproof, waterproof, and beautiful appearance; It can be used for both blowing and ventilation, making it a good 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.
The negative pressure fan is installed outside the window of the workshop. Generally, it selects a lower air outlet and draws air outward to extract odorous gases. Generally, it is widely used in factories, farms, greenhouses, etc. When used in conjunction with a wet curtain, it can achieve better cooling effects. No matter how hot, the water curtain fan cooling system can reduce the temperature to below 30 ℃.
Seven advantages of negative pressure fans:
1. The outer frame adopts traditional processing technology with thin thickness.
2. New twisted and stamped fan blades, reasonable blade shape angle, and air flow effect.
3. The belt pulley with multiple reinforcing ribs is sandblasted to improve aesthetics, remove internal stress, and enhance strength.
4. The outer frame and louver are both molded from galvanized steel plate, the fan blades are one-time stamped, fastened with forged gas screws, and accurately balanced and calibrated by a computer.
5. Low noise, large air volume, low power consumption, and obvious cooling effect. It can be used for blowing or ventilation.
6. Louver connectors are made of high-strength plastic steel or aluminum leaf materials, with tight closure and long service life.
7. The shutter is automatically opened and closed by an automatic control system, which is dustproof, waterproof, and beautiful in appearance.

The negative pressure fan has the characteristics of low investment cost, large air volume, low noise, low energy consumption, stable operation, long service life, high efficiency, and automatic opening and closing of the louvers to achieve dustproof, waterproof, and beautiful appearance; It can be used for both blowing and suction, making it a choice for cooling and ventilation in modern workshops. Environmentally friendly and energy-saving negative pressure fans will become the mainstream in the ventilation and cooling equipment market. So, what scenarios can negative pressure fans be used in? Welcome to read the following text.
Scope of Application of Negative Pressure Fan
1. For ventilation purposes
Installed outside the workshop window, usually choose a lower air outlet, extract air outward, and extract odorous gas; There are many applications such as general negative pressure fan factories.
2. Used in conjunction with wet curtains
Used for cooling the workshop 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 30C, and there is a certain humidity.
3. Applicable scope of negative pressure fan
A. Suitable for workshops with high temperatures or odors: such as heat treatment factories, casting factories, plastic factories, aluminum profile factories, shoe factories, leather goods factories, electroplating factories, printing and dyeing factories, and various chemical factories.
B. Suitable for labor-intensive enterprises such as clothing factories, various assembly workshops, and internet cafes.
C. Ventilation and cooling of horticultural greenhouse and livestock farm.
D. Especially suitable for places that require cooling and a certain humidity. Such as cotton mill, wool mills, linen mills, weaving mills, chemical fiber mills, warp knitting mills, texturing mills, knitting mills, silk mills, sock mills and other textile mills.
E. Suitable for the field of warehousing and logistics
4. Used as an exhaust fan
The efficiency of general exhaust fans (commonly known as Yanggu fans) is relatively poor. A single exhaust fan can blow less than a few people, while a negative pressure fan is not, whether it is used on the ground or hanging in the air. Generally, 4 units are used in a 1000 square meter workshop, which has the effect of wind blowing all over the house.
