The Eco-Aire Rigid Air Filter is a steel-cased air filter engineered to provide medium and high efficiency filtration combined with a prolonged life cycle. Its box filter construction eliminates the need for retainer and special external wire media supports. The perimeter frame is constructed of high strength, corrosion resistant galvanized steel. Galvanized steel braces are secured to both the air entry and exit sides along with all four interior sides adhered to the filtration media to maintain filter integrity.
Each Eco-Aire Rigid Filter utilizes a high-density filter media composed of ultra-fine glass fibers laminated to reinforced, high strength nylon backing. These Rigid Air Filters provide efficiencies in 65%, 85%, and 95%. This product is listed and rated by Underwriters Laboratories as U.L. 3TVA.
