Negative pressure fans use the cooling principle of air convection and negative pressure ventilation to naturally inhale fresh air from the opposite doors or windows at the installation site and quickly and forcibly discharge the hot indoor gases. Any poor ventilation problems outdoors can improve the cooling and ventilation effects. The negative pressure fan discharges air outwards to reduce the indoor air pressure and thin the indoor air to form a negative pressure zone. The air flows into the room due to the compensation of air pressure difference. In practical applications in industrial plants, negative pressure fans The pressure fans are centrally installed at the air inlet on one side of the factory building. The air on the other side of the factory building forms a convection blow from the air inlet to the negative pressure fan. During this process, the doors and windows near the negative pressure fan are kept closed to force the air to flow from the air inlet to the negative pressure fan. The side doors and windows are compensated and flow into the workshop. The air flows into the workshop from the air inlet in an orderly manner and is discharged from the workshop by the negative pressure fan. The ventilation rate can be as high as 100%. The ventilation rate can be as high as 100%. Through specific engineering design, the ventilation is designed according to needs. Speed and wind speed Any high-heat harmful gases, dust and smoke can be quickly discharged from the workshop. 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.
