Roll-O-Mat® Automatic Roll Filter Media Roll-O-Mat filter media were developed for use in Roll-O-Matic® automatic renewable media air filters, invented by AAF International. Available in roll widths to fit all filter sizes and all manufacturers' filters, Roll-O-Mat continues to be the most widely used and most dependable brand in the industry. Better Air is Our Business ® Roll-O-Mat Gold Premium Quality Media Roll-O-Mat Gold media provides a combination of high performance and strength. • 2" thick media of continuous filament fiberglass • Heavy application of Viscosine® adhesive • Rolls are 65' long • Gold tint on air leaving side Roll-O-Mat Blue Top Quality Media Roll-O-Mat Blue media combines excellent operating performance with low initial purchase price. • Available 1" and 2" thick • Continuous filament fiberglass media • Medium application of Viscosine adhesive • Rolls are 65' long • Blue tint on air leaving side Roll-O-Mat Green Synthetic Media Designed for general air filtration applications where a synthetic media is preferred. • 100% polyester fibers • Available 1 /2" and 1" thick • Medium application of Viscosine adhesive • Rolls are 65' long • Green tint on air leaving side Roll-O-Mat Red UL Class 1 Ideal for higher temperature applications (up to 300°F). • 2" thick media of continuous filament fiberglass • Dry, no adhesive • Rolls are 65' long • Red tint on air leaving side High Fiber Content Roll-O-Mat Gold has more glass fibers, more than 81 /2 miles per square foot, than any competitive media. Higher fiber content provides more dirt catching media surface, providing higher arrestance and greater dust holding capacity. High Compression Strength Extends Filter Life Resin applied to the fiberglass during spinning is cured in an oven to form a strong bond at each fiber intersection. Bonded fibers increase compression strength and prevent faceloading. Air moves throughout the entire thickness of the media utilizing the full cleaning potential of the media. Progressive Density Increases Arrestance Fibers on the air entering side are interlaced in an open pattern which becomes progressively tighter. Dirt loads from back to front, taking advantage of the entire thickness of the media. This construction prevents faceloading and increases arrestance and dust holding capacity. Designed for Dependable Performance Progressive Density Media Construction

Roll-O-Mat® Viscosine® Retains Dirt Viscosine adhesive helps retain particles as they impinge on fibers, preventing them from breaking away and flowing downstream. Glass Wires Prevent Bypass Leakage Glass wire strands on the air leaving side of the media provide high tensile strength to prevent bypass leakage. Competitive roll with low tensile strength causes the media to "neck" and pull out of the side channels. Unfiltered air is allowed to bypass the media.
