shutter exhuast fan 20 inch

 

 

1> The exhaust fan belongs to an axial flow fan. It is mainly used in negative pressure ventilation and cooling engineering and is called industrial exhaust fan. The exhaust fan has the characteristics of super large air duct, super large blade diameter, super large exhaust air volume, ultra-low energy consumption, low speed, low noise, etc. ‍‍KINGHI exhaust shutter fan supplier will provide you best qualtiy fan.
It can be used together with cooling water curtain to solve ventilation and cooling problems at one stroke. During the operation of the exhaust fan, a negative pressure environment will be formed indoors. If a cooling water curtain is installed on the wall on the other side of the outlet of the exhaust fan, the exhaust fan will not only discharge the indoor hot air out of the room, but also enter the room through the cooling water curtain to inhale the indoor low-temperature air containing rich water vapor. so as to achieve the effect of ventilation and cooling.

2>When the exhaust fan discharges air outward, the indoor air pressure will drop, the indoor air will become thinner, forming a negative pressure area, and the air will flow into the room due to the compensation of air pressure difference. In the practical application of industrial plants, the exhaust fan is usually installed on one side of the plant, and the air inlet is on the other side of the plant. The air from the air inlet to the exhaust fan forms convection blowing. During this process, the doors and windows near the exhaust fan remain closed, forcing air to flow into the workshop through the doors and windows at the air inlet. The air flows into the workshop from the air inlet, flows through the workshop and is discharged from the workshop by the exhaust fan in line and orderly. The ventilation is thorough and efficient, and the ventilation rate can reach 99%. Through exhaust shutter fan supplier specific engineering design. Design of exhaust shutter fan speed and wind speed as required. Any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any problem of poor ventilation can be completely solved at one time. The ventilation effect can be achieved within a few seconds after the fan is turned on. kinghi industrial exhaust fans manufacturers will provide you good service。

3> The exhaust fan can quickly discharge the indoor stuffy air. Draw the air on the other side of the outdoor into the room. So that the temperature is equal to the outside temperature and the temperature in the workshop will not rise. In the process of air flow. it will take away heat from the human body. The air flow accelerates the evaporation of sweat and absorbs heat from the human body. Making the human body feel cool and as cool as the natural wind.
