SE UL Hoods

Clean Aire HEPA/Carbon In-Line Filtration Systems

Clean-Aire HEPA and Carbon Filter Packs are designed to be mounted incline in the exhaust ducting from a fume hood or contaminant source up to 1500 cfm.

The filter pack includes a galvanized steel housing with hinged and gasketed access door for filter change-out and molded composite resin inlet and outlet plenum with duct connection collars sized to meet specification.

Both filters include a 30% pleated prefilter and can be paired together for applications that require particulate and fume removal.

Clean Aire In-Line HEPA Filtration Systems

HEMCO HEPA filter packs effectively collect particulate contaminants from the exhaust air stream. HEPA filters are 99.999% effective at removing particulate .3 micron and larger. The filter pack housing features a hinged access door with gaskets and spring latches for convenient filter change. Inlet and outlet plenum's with duct connection collars are installed. The HEPA
filter pack can also be paired with a carbon filter pack to remove chemical fumes and odors.

Note: HEMCO recommends a minihelic or magnehelic gauge to monitor the airflow differential across the filter. The static pressure indicated would alert when to change filter. The gages can be hood or filter mounted. We recommend ordering a back-up replacement filter.

HEPA Filter Bag In Bag Out System

Filter Housing is fabricated of type-304 stainless steel & requires (1) carbon filter absorber, (1) 24” X 24” X 2” 30% pleated prefilter & (1) bag.

Bag-In bag-out filters are designed to meet air filtration requirements to handle hazardous fumes and vapors. The housing incorporates a ribbed bagging ring around the side access door over which a specially designed plastic bag is attached. Filters are then installed and changed through the bag to reduce the risk of exposure to personnel

Minihelic Gauge Gauge monitors the pressure differential across the HEPA filter, Gauge conveniently mounts on the fume hood or on the filter housing. Measure range is from 0 to 2.0” wg Gauge is 3” dia. with 5% accuracy Cat. No. 51300

Magnehelic Gauge Gauge measures static pressure across the HEPA filter. Mounts on the fume hood or the filter housing. Range of measurement is from 0 to 2” wg. Gauge is 5” dia with 2% accuracy. Cat. No. 51301

Clean Aire In-Line Carbon Filtration Systems

HEMCO carbon filter packs are used in laboratory exhaust and supply systems to remove chemical odors and vapors from the airstream. Filters are loaded with virgin coconut activated carbon to efficiently absorb organic solvents and acid fumes. The
filter pack housing features a hinged access door with gaskets and spring latches for convenient filter changes. Inlet and outlet plenum's with duct connection collars are installed. The carbon filter pack can also be paired with a HEPA filter pack to collect particulate contaminants.

A standard “01” activated carbon filter for organics is included. HEMCO recommends the sampling kit to check if there has been a breakthrough in the carbon filter, and ordering a back-up replacement filter.

Bag-In bag-out filters are designed to meet air filtration requirements to handle hazardous fumes and vapors. The housing incorporates a ribbed bagging ring around the side access door over which a specially designed plastic bag is attached. Old filter is removed then new filters are then installed and changed through the bag to reduce the risk of exposure to personnel. Note: The carbon filter is not included with the housing. We also, recommend the sampling kit below to check if there has been a break through in the carbon filter, and ordering a back-up replacement filter.
