Multi-layer filters (Series HC) are paint stop or paint collectors consisting of more layers of special kraft alveolar paper with honeycomb openings and decreasing sections, bonded to one each other by sewing. The multi-layer filters series HC burn only if sparked off with direct flame, but in case of fire they do not emit toxic fumes not being treated with fireproofing products such as organo-metallic salts.
 
On request, we can supply cells, sleeves and pocket filters with multilayer filter inside.
