CleanAire filters are designed to be mounted inline in the exhaust ducting from a fume hood or contaminant source up to 1500 cfm. The HEPA and carbon filter packs include a galvanized-steel housing with hinged and gasketed access door to ease filter change-out. Molded-composite resin inlet and outlet plenums and duct-connection collars are sized to meet specification. Both filters include a 30 percent pleated prefilter and can be paired together for applications that require particulate and fume removal.
