NEED A CUSTOM SIZE? Visit our online store: www.airexco.net. The 82-R MERV 11 pleated filters are available in a wide range of sizes for all commercial, industrial and residential applications. The filter media is a 100% synthetic, electrostatically charged media, designed to attract and hold airborne contaminants. This results in a higher efficient filter, 80-85 @ 3-5 micron, over 90% @ 7-10 micron without sacrificing airflow. Initial resistance of a 2� deep filter is just .36� w.g. @ 500 FPM. The enclosing frame of the 82-R is constructed of a rigid, heavy duty moisture resistant beverage board. The support members are an integral part of the frame and are bonded to each pleat on both sides to insure pleat spacing and stability. The filter pack is bonded to the inside periphery of the frame, thus eliminating the possibility of air bypass. The media support grid is available in expanded wire with an effective open area of not less than 96%. The wire grid is bonded to the filter media to eliminate the possibility of media oscillation and media pull away.
