The fresh air fan is an effective air purification equipment that can circulate indoor air. On the one hand, it discharges the dirty indoor air to the outside, and on the other hand, it sterilizes, disinfects, and filters the fresh outdoor air. After taking measures, it is then input into the room, so that the room is filled with fresh and clean air all the time.
The fresh air blower uses the patented fresh air convection technology to achieve convection of indoor air through independent air supply and induced air, thereby maximizing indoor air replacement. The fresh air blower has a built-in multi-functional purification system to ensure that indoor air does not enter the room. The air is clean and healthy. Fresh air fans are mainly divided into two types: exhaust fresh air fans and supply fresh air fans. They can be installed in most indoor environments and are easy to install and comfortable to use. The fresh air blower is a healthy companion for home life.
