Seven Advantages of Negative Pressure Fan
Negative pressure fan is a new type of fan, mainly used in negative pressure ventilation and cooling engineering, belonging to the axial flow fan, known as negative pressure fan. The negative pressure ventilation and cooling engineering includes the meanings of ventilation and cooling, and the problems of ventilation and cooling are solved simultaneously. The negative pressure fan is mainly installed outside the workshop window. Generally, the lower air outlet is selected to extract air and odor. It can be used in all places requiring ventilation. Nowadays, negative pressure fans have become necessary equipment for cooling and ventilation in major factories. Let’s take a look at the seven advantages of negative pressure fans with my editor.
1. The outer frame adopts traditional processing technology and has a relatively thin thickness.
2. New folding and punching fan models with reasonable blade shape angle can achieve large air volume.
3. Multiple ribbed pulleys, sandblasted, improve appearance, increase internal stress, and enhance strength.
4. The outer frame and shutter are both molded from galvanized steel plate, the fan blades are formed by one-time stamping, fastened with forged gas screws, and calibrated by computer balance.
5. Low noise, large air volume, low power consumption, and significant cooling effect. It can be used for both blowing and ventilation.
6. Louver connectors are made of plastic steel or aluminum strength blades, made of materials that are tightly closed and have a long service life.
7. Through the automatic shutter control system, the automatic opening and closing of the fan shutter can be achieved, achieving the goal of dust prevention, waterproof, beautiful appearance, and generous appearance! Select the internal ventilation method.
1、 High air volume and fast ventilation and exchange rate
Negative pressure fans have advantages such as super large air ducts, super large blade diameters, and super large exhaust volumes. Compared to traditional fans, negative pressure fans have a large air volume, fast ventilation speed, and can exhaust and dissipate heat in a short period of time, making them a suitable choice for factory ventilation and cooling.
2、 Suitable for large-scale ventilation and cooling
Negative pressure fans are mainly used in negative pressure ventilation cooling engineering, which includes two aspects: ventilation and cooling. Both ventilation and cooling are solved simultaneously. In addition, negative pressure fans can also be applied in fields such as positive pressure water curtain environmental air conditioning, positive pressure air supply, positive pressure blowing, etc., with a wide range of applications, suitable for large-scale ventilation, ventilation, and cooling.
3、 Corrosion resistance, acid and alkali resistance, long service life
Compared to traditional fans, negative pressure fans, especially fiberglass negative pressure fans, are usually made of outdoor materials with strong weather resistance. They are not only acid and alkali resistant, but also corrosion-resistant, and have the advantage of longer service life among a wide variety of negative pressure fans, which can avoid many troubles of later maintenance.The negative pressure fan 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, and high efficiency. The automatic opening and closing of the louvers can achieve dust prevention, 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 in the ventilation and cooling equipment market.
The negative pressure fan is installed outside the workshop window, usually with a lower air outlet and outward ventilation to extract odorous gases. It is commonly used in factory workshops, breeding farms, greenhouses, etc. When used in combination with a wet curtain, it can achieve better cooling effect. No matter how hot it is, 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 and has a thin thickness.
2. New twisted and stamped fan blades, reasonable blade shape angle, and air flow effect.
3. Multi ribbed pulley, sandblasted to improve aesthetics, remove internal stress, and enhance strength.
4. The outer frame and louvers are both manufactured using galvanized steel plate molds, and the fan blades are stamped and formed in one go. They are fastened with forged gas screws and accurately balanced and calibrated by a computer.
5. Low noise, high air volume, low power consumption, and obvious cooling effect. It can be used for blowing or ventilation.
6. The louver connectors are made of high-strength plastic steel or aluminum leaf materials, which are tightly closed and have a long service life.
7. The louver is automatically opened and closed by an automatic control system, which is dustproof, waterproof, and aesthetically pleasing in appearance.
