The V-shape of the filter creates a Venturi effect (increasing the airflow rate on the filter) and forces the air with the particle colors to change direction. In the path that follows, the air places the color on the sides of the filter while the air coming out of the filter is clean.
Installing the paper filter is very easy. In an absorbent there may be layers of filters. The filter can be mounted vertically and horizontally. The cabin must be fitted with fresh filtered air. For the filtering of the fresh air we use a particle filter type G3-G4 and F5. When there is a big pressure drop in the booth, we need to change the filters because they are full.
