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 65’ Roll-O-Mat Blue is made up of top quality fiberglass media. Resin-bonded fibers on the air entering side are interlaced in an open pattern which becomes progressively tighter. This construction prevents faceloading and increases arrestance and dust holding capacity. A series of flexible glass “wires” running the length of the roll provide supplemental support while strands on the air leaving side provide high tensile strength. The glass fibers are coated with a medium application of Vicosine gel. Viscosine is a non-toxic, non-flammable adhesive that helps prevent particles from breaking away and flowing downstream. Blue Roll-O-Mat media is designed for use in all models of the AAF Roll-O-Matic automatic roll filters. It is also designed for use in most competitive automatic roll filters. The Blue media can be used as a primary filter in general air filtration applications or as a prefilter to higher efficiency filters.
