Visit PTAC Solutions for American Air Filters, Dust Collectors, Air Pollution Control Equipment and other types of Air Filtration. We offer a Full Line of Replacement and Custom Made Air Conditioning Filters for both Residential and Commercial Air Filter Systems. The Roll-O-Mat Green contains 100% polyester fibers with a medium application of Viscosine gel. Viscosine is a non-toxic, non-flammable adhesive that helps prevent particles from breaking away from the fibers and flowing downstream. A synthetic mesh backing material is applied to the air leaving side of the media to increase strength. Roll-O-Mat Green media is designed for use in all AAF models of the Roll-O-Matic filter as well as most competitive automatic roll filters. The Green’s synthetic makeup makes it useful for special process applications where user specifications do not permit fiberglass media.
