improve the air quality in the house, reduce the pollution hazard in the kitchen, improve the indoor sanitary conditions, prevent the cross flow of polluted air indoors and improve the indoor air quality.

the main function of the flue check valve is to prevent smoke from flowing backwards and reinjection, which plays a blocking role. On one side, normal smoke can be removed, and on the other side, it can prevent smoke from flowing backwards. The unique pressure change and gas extraction technology can make the air inlet generate static pressure or even negative pressure, which not only can easily meet the check function, but also fundamentally solve the problems of oil smoke backflow, smoke odor and so on.
