Service Rolls ~ air filtration media are manufactured in selected widths, prepared in roll lengths that make manageable roll sizes. In most cases, a single cut across the roll will produce a ready-to-install filter pad. The following media are offered as service rolls: Spun Glass: This is a rigid, nominal 3/8” thick, dry spun glass. It is typically used to make rigid pads for use in room unit air conditioners. It is designed for use without a frame. Since it is untreated, it will not harm the plastic frequently used in the construction of room units. Foam: A rugged polyurethane foam that is designed for use in room unit air conditioners and in pad-holding frames. It is washable and will withstand repeated cleaning with mild soap and water. Foam service rolls are available in 1/4”, 1/2”, 1” and 2” media thicknesses. They are washable for repeat use. Aluminum: The aluminum service roll is an expanded aluminum mesh of the type used in room unit air conditioners. It is a nominal 1/4” thick dry filter media that requires the addition of a dust adhesive for effective filtration.
