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