Features:

This product abandons the louvered sealing structure of the traditional fan, and adopts an advanced closed structure with two front doors, which has small wind resistance, good sealing and high efficiency. Compared with the traditional blinds, the structure reduces the air loss rate by 75%, reduces the energy consumption by 12-15%, and is more reliable, convenient and easy to clean.
On the premise of not increasing the motor power, the air volume of this fan is increased from the original 43,940 cubic meters per hour to 51,020 cubic meters per hour.

Not only that, but also A new design has been carried out in terms of the position and method of motor installation, and the connection method of the air collecting tube.
