Purolator® Serva-Cell® Extended Surface Filters Are Used For High Humidity, Turbulent Airflow, Intermittent Water Exposure And Elevated Operating Temperature Conditions.
Box filter eliminates need for retainers and special external wire media supports. High surface area to depth ratio provides the maximum amount of effective filter media in areas of minimum in-line duct space. Media is made using a continuous sheet of non-combustible, waterproof micro-fiberglass. Radi-edge pleat configuration promotes maximum exposure of media surface area to airflow. Corrugated aluminum separators for support. Framing is made using corrosion resistant galvanized steel casing. Media is bonded using non-toxic adhesive on the upstream side.
