Clean-Aire HEPA / Carbon Filtration Systems

HEMCO Clean Aire HEPA Filter Paks effectively collect particulate contaminants from the exhaust air stream. HEPA filters are 99.999% effective at removing particulate .3 micron and larger. The filter pak housing features a hinged access door with gaskets and spring latches for convenient filter change. Inlet & outlet plenum with duct connection collars are installed. HEPA Filter Pak can also be paired with a carbon filter pak 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 gauges 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. 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.

Clean Aire Carbon Filtration System

HEMCO carbon filter paks 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 pak housing features a hinged access door with gaskets and spring latches for convenient filter changes. Inlet and outlet plenum with duct connection collars are installed. The carbon filter pak can also be paired with a HEPA filter pak to collect particulate contaminants. For other types of contaminates, please see the chart below.

Note: 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.

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.
