Polyester filter with low pressure drop and high dust accumulation capacity. Totally impregnated with an adhesive resin, the filter media also blocks the collected particles thanks to a progressive structure. It is mainly used for spray booths or painting systems as a ceiling filter in the final stage of filtration, ensuring 100% stoppage of particles >10 µm that could cause visual imperfections on the surface. A special reinforcement mesh in the air outlet side reduces the risk of breakage of the mat during installation and increases its stability. It is also resistant to solvent vapours and does not contain silicone.
