General structure of cellular corrugated filters (FyaG)

FyaG filters consist of a frame made of cardboard or galvanized steel,
inside of which filter material is placed in the form of corrugations, resting on the air outlet side on a corrugated (wavy) mesh.

Maintenance of cell pleated filters (FyaG)

During the operation of filters, their aerodynamic resistance should be monitored according to the readings of a pressure gauge connected to fittings located in the walls of the air-cleaning chambers before and after the filters. When the differential pressure recommended for a given filter is reached, or based on the available pressure in the system, the filters must be replaced.
