The paper for our filters is made from high-grade cellulose fibers impregnated with special resins. These materials are treated in a special production process: special pre-warming prepares the paper for the embossing of vertical ridges. Afterwards, the paper is folded according to requirements. Then the impregnation is cured to make the paper mechanically stable and to make it resistant to chemical and thermal influences. The result: filters with stable pleat geometry that prevent the feared forming of blocks under high load and ensure that air, oil or fuel can flow freely through the paper at all times. The filters can remove particles as small as 1 micron, depending on the requirements, and offer safe conditions for highest contaminant elimination.

Filters made from paper are used in air, fuel, oil and hydraulic filters.
