Product Description

Negative Pressure Fan
Negative pressure fans use the cooling principle of air convection and negative pressure ventilation. They are machines that naturally inhale fresh air from the opposite side of the installation location - the door or window, and quickly force the hot and stuffy air in the room to be discharged outdoors. Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90%-97%. Negative pressure fans are the latest type of ventilators and belong to axial flow fans. They are called negative pressure fans because they are mainly used in negative pressure ventilation and cooling projects. Negative pressure ventilation and cooling projects include ventilation and cooling, and ventilation and cooling problems are solved at the same time. Negative pressure fans are also used in positive pressure water curtain environmental protection air conditioning, positive pressure air supply, positive pressure blowing and other fields. Negative pressure fans have the characteristics of large size, super large air duct, super large fan blade diameter, super large exhaust volume, ultra-low energy consumption, low speed, and low noise. Negative pressure fans are mainly divided into galvanized square negative pressure fans and glass fiber reinforced plastic trumpet negative pressure fans based on structural materials. 
 

Product Feature:
1. Low investment cost;

2. Large air volume, low noise, low energy consumption, stable operation, long life, high efficiency, etc.;

3. The shutters open and close automatically to prevent dust and water, and are beautiful and generous; it can blow air or exhaust air, and is the best choice for cooling and ventilation in modern workshops.

Ventilation principle:
The negative pressure fan discharges air to the outside, causing the indoor air pressure to drop, making the indoor air thinner, forming a negative pressure area, and the air flows into the room due to the pressure difference compensation. In the actual application of industrial plants, the negative pressure fan is installed on one side of the plant, and the air inlet is on the other side of the plant. The air forms a convection blow from the air inlet to the negative pressure fan.In this process, the doors and windows near the negative pressure fan remain closed, forcing the air to flow into the workshop through the doors and windows on the air inlet side. The air queues and flows into the workshop from the air inlet in an orderly manner, flows through the workshop, and is discharged from the workshop by the negative pressure fan. The ventilation is thorough and efficient, with a ventilation rate of up to 99%. Through specific engineering design, the ventilation speed and wind speed are designed according to needs, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problems can be completely solved at one time. The ventilation effect can be achieved within a few seconds of turning on the fan.

Cooling principle:
1. Ventilation and cooling: The temperature of the place that needs ventilation is higher than the outdoor temperature due to sunlight irradiating buildings, machinery and equipment, human body and other heat sources.Negative pressure fans can quickly discharge indoor heat, making the room temperature equal to the outside temperature, so that the temperature in the workshop will not rise. 
2. Air flow takes away the body heat, accelerates the evaporation of sweat and absorbs the body heat, so that the body feels cool, as cool as natural wind.
3. Negative pressure fans only have the function of ventilation and cooling, and have no refrigeration function. Coolness is a feeling of the human body. It is ignorant to say how much the negative pressure fan can reduce the temperature.
4. Used in conjunction with the water curtain, the temperature in the workshop can be controlled within 28 degrees Celsius during the hottest time in summer. But the cool feeling of the human body can be compared with that of air conditioning. People who face the water curtain for a long time will feel cold and unbearable.
