In filtering elements production there is applied filtering paper based on cellulose and impregnated with phenol, epoxy resins.

The purpose of impregnations with resins is the protection of filtering elements from high temperatures and aggressive chemical compounds, which contains in oil.

Nowadays in order to improve absorbing capacity if filtering element there are applied multi-layers materials with different structures and various filtration properties for each layer.

Also are applied synthetic filtering materials or their combinations. Such materials are mainly intended for filtration of synthetic oils and are used for oil filters, which designed for present-day motor vehicles.
