In people's mind, the negative pressure fan is used to cool down like air conditioning, only installed and used in summer why there are people in such cold weather to install the negative pressure fan? Let's discuss its application functions:

1. Ventilation: airtight and semi-airtight space, the air is not circulating for a long time. If people walk into the space without forced ventilation, they will feel breathing is not smooth, so they need ventilation.

2, smoke exhaust: some workshops have a little electric welding and other types of small amount of smoke generation, generally they are unorganized emissions, so basically are using Jiayun negative pressure fan exhaust effect is the best.

3, dust discharge, part of the space sometimes produce a small amount of dust, basically is no organized discharge, using negative pressure exhaust fan is efficient and electricity saving.

4, heat discharge: there is no space, there is a type of furnace, oven and other high heat heating equipment, in the vicinity of the temperature can be as high as 200 degrees or so, emitted into the space can make the space temperature rise to 50 degrees or so, this is to use it can quickly exhaust the hot gas.

So Jiayun negative pressure fan is not only a cooling product, it is a ventilation equipment.
