RIGID CELL FILTER The Rigid Cell Filter is an extended surface medium and high efficiency rigid air filter. These are available in Merv 14, Merv 13, Merv 11 and Merv 9 in both synthetic and fiberglass. The filter media consists of high quality synthetic media, which forms a lofted filter blanket. This blanket is laminated to a high strength, reinforced backing. The media is then continuously bonded to an expanded metal support grid and is shaped into a wedge design, assuring maximum utilization of the filter media. The pleated filter media is reinforced and stabilized through the use of pleat spacers. The pad is enclosed in a corrosion resistant galvanized steel frame or a heavy plastic frame, depending upon the application. Headers are available upon request. This filter has been engineered to provide high efficiency filtration combined with prolonged life cycles. It is an ideal choice for variable air volume systems. Available in 6” and 12” depths.
