Glass fiber is used as the filter material. The medium is impregnated
a substance with adhesive properties to increase absorption and ability
storing dust and reducing the pressure drop of the clean filter.
From the air intake side the fiber is rare and has a loose weave. The diameter of the fibers narrows towards the air outlet to collect as many particles as possiblepolluted air. There are two options for filter housing. The first is a filter in a galvanized frame. Due to the use of a mesh after the inlet and outlet throne, the air is increased rigidity, allows you to maintain the filter material so that the filter is stable.
The second option is a cardboard frame. Made of impregnated cardboard, thanks to which it is resistant to moisture.
