Industrial ventilating fans mainly use the principle of air convection to perform their work. They are mainly installed on windows. Fresh air is naturally drawn in from the opposite door or window at the installation site, so that indoor hot air and dirty air are quickly discharged to the outside, attracting fresh air. indoor.

The ventilation method of the exhaust fan is divided into three types: exhaust type, suction type and combined type. The exhaust fan type mainly lets air in from the natural air inlet, and uses the exhaust fan itself to exhaust the exhaust gas in the air. The suction type fan is mainly based on the ventilation fan, which can suck in fresh air. The ventilating method that exhausts the dirty air from the natural exhaust port is all completed by the ventilating fan alone. There are three types of ventilation, exhaust type, suction type and combined type. The exhaust fan type mainly lets air in from the natural air inlet, and uses the exhaust fan itself to exhaust the exhaust gas in the air. The suction type fan is mainly based on the ventilation fan, which can suck in fresh air. The exhaust of dirty air from the natural exhaust port is all done by the ventilation fan alone.

Maintenance personnel of industrial ventilation fans must pay attention to:

1. It can only operate when the fan equipment is completely normal.

2. If the fan equipment is started after maintenance, please pay attention to whether all parts of the fan are normal.

3. Regularly remove dust, dirt, water and other impurities inside the fan and gas pipeline, and prevent rust.

4. Repair of fan equipment is not allowed to be carried out during operation.

The above are the ventilation methods and maintenance items of industrial exhaust fans, and I hope to help you.
