Air intake filter for commercial ventilation, air conditioning of the building

Air intake filters are the primary filter used in the dust-free cleanroom of the ventilation system. Its function is the most possible to removes large particles of dust, leaves, hair and other pollutants in the air. To reduce burden for next stage medium efficiency and high efficiency filter.

Generally speaking, air intake filters are made of chemical fiber cotton and metal frame, it can be designed in different styles such as flat type, folding type, bag type and external surface, etc. According to different styles, its structure and design will be different, but the filter efficiency can be basically in the same.

The filtration efficiency of air intake filters is mainly G3 G4 and M5, which can effectively remove more than 80-98% of the large particles of dust in the air.

At present, these filters are mainly used in common ventilation systems such as medical, pharmaceutical, food, health, safety, electronics, precision machinery laboratories and so on. They can also be used in commercial ventilation systems. At the same time, they can be designed to have the function of removing odor such as activated carbon.
