The role of the exhaust fan 1. The exhaust fan generally circulates the indoor air, and it should be able to quickly remove the solvent in the room after volatilization, so as not to cause the solvent content in the indoor air to be too high, thereby causing explosion or poisoning.
The function of the exhaust fan 2. The exhaust fan is driven by the motor to drive the fan blades to rotate and drive the airflow to exchange indoor and outdoor air. Also called a ventilation fan. The purpose of the exhaust is to remove the dirty air in the room and adjust the temperature, humidity, and sensory effect.
In the process of exhausting air from the exhaust fan, 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 the air pressure difference. In the practical application of industrial plants, the exhaust fans are usually installed on one side of the factory building, the air inlet is on the other side of the factory building, and the air flows from the air inlet to the exhaust fan to form convection blowing.
During this process, the doors and windows near the exhaust fan are kept closed, forcing air to flow into the workshop through the doors and windows on the side of the air intake. The air flows into the workshop in an orderly manner from the air inlet, flows through the workshop, and is discharged from the workshop by the exhaust fan.
The ventilation is thorough and efficient, and the ventilation rate can be as high as 99%. Through specific engineering design, the ventilation speed and wind speed are designed according to the needs, any high heat, harmful gas, dust, and smoke can be quickly discharged from the workshop, and any poor ventilation problems can be completely solved at one time. Ventilation is achieved within seconds of turning on the fan.
