CleanAire HEPA and Carbon Filter Paks are designed to be mounted inline in the exhaust ducting from a fume hood or contaminant source up to 1,500 cfm. The systems include a galvanized-steel housing with hinged and gasketed access door for filter changeout and molded composite-resin inlet and outlet plenums with duct-connection collars sized to meet specification. Both filters include a 30-percent pleated prefilter. They can be paired for applications requiring particulate and fume removal.
