Compared with the traditional exhaust fan, the negative pressure fan has obvious advantages:
(1) Convenient: Manual shutter control enables normal lighting and ventilation when no fan is needed.
(2) Low input: large exhaust capacity of single machine, wide application range. At the same temperature, the project has a high cost performance ratio.
(3) Environment friendly: no compressor, no refrigerant, less pollution and low noise.
(4) Easy to clean: continuously provide fresh and clean air for the workshop, and increase the oxygen content in the air.
(5) Easy maintenance: easy to install, less maintenance, easy to operate, no professional maintenance required.
(6) Durable: heavy aluminum die cast blades, high temperature resistance, aging resistance, and no deformation.
