Chemical binders are not used in the production of filter materials, so that they can be recycled conditionally. While the types used in the general industry are dry, powder adhesive is impregnated with the types used in the final filtration of painting systems. The fresh air side is covered with mesh reinforcement and compacted with polyester fibers, compressed and straightened. The polyester reinforcement layer on the fresh air side prevents damage during assembly and protects the filter against possible dust escaping. The optimal separation of particles damaging the paint is maintained at high temperatures. Due to the increasingly frequent texture towards the depth, it is used not only for the surface of the material, but also for keeping the whole depth dust.
