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.

Compared to the GC Series, this model presents on the air outlet side a layer of synthetic polyester media which makes it more efficient.
 
On request, we can supply cells, sleeves and pocket filters with multilayer filter inside.
