Key Features and Specifications
Each filtration system includes a galvanized steel housing with a hinged, gasketed access door, allowing safe and convenient filter replacement.
Molded composite resin inlet and outlet plenums are provided and include duct connection collars sized to meet project airflow specifications.
Both filter packs include a 30% efficient pleated prefilter and can be used:
Individually for particulate or vapor control
Together for combined particulate and chemical fume filtration
This modular approach allows laboratories to configure filtration systems based on the specific contaminants present in the workspace.
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.
