CleanAire filter packs 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 includes a galvanized steel housing with hinged and gasketed access door for filter changeout. Molded composite resin inlet and outlet plenums with duct connection collars are sized to meet specification. Both filters include a 30 percent pleated prefilter. They can be paired for applications that require particulate and fume removal.
