Clean Aire HEPA Filtration Systems

HEPA Filter Bag in Bag System
Filter housing is fabricated of type-304 stainless steel and includes (1) HEPA-99.99% efficient at 0.3 microns and larger, (1) 24” x 24” x 2” 30% pleated prefilter, and 1 bag. Bag In-Bag Out filters are designed to meet air filtration requirements to handle hazardous particulate materials. 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: 1. The HEPA filter is not included with the housing. Please select HEPA filter below. 2. We recommend a minihelic or magnehelic gage to monitor the airflow differential across the filter. The static pressure indicated would alert when to change the filter. The gages can be hood or filter mounted. 3. We recommend ordering a back-up replacement filter.

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. # 51300
Magnahelic Gauge Gauge measures static pressure across the HEPA filter. Can mount 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. # 51301

Clean Aire Carbon Filtration System

Clean Filter Bag in bag out System
The Carbon Filter Pak is engineered to remove undesirable fumes and odors from a Uniflow fume hood exhaust system. The filter pak housing is constructed with a convenient latched/hinged access door for filter change out. Inlet and outlet plenums with duct connection collars are installed. Note:
1. The carbon filter is not included with the housing. Please review the adjacent contaminant chart and select the appropriate carbon filter. 2. We recommend that the sampling kit below to check if there has been break through in the carbon filter. 3. We recommend ordering a back-up replacement filter.

HEMCO's Inline Fume & Vapor Scrubbers

Scrubber systems offer high efficiency and minimal maintenance on meeting pollution control requirements. Provides excellent air pollution control for water soluble fumes and odors by moving contaminated air through a filter pack media exposing over forty square feet of surface per cubic foot. Contaminant is collected on filter media surface and rinsed off with water. Excess water is then mechanically removed and cleaned air is released. When conditions require, chemical additives can increase absorptive capacity of the scrubber. Unit includes integral re-circulation tank and pump which significantly reduces water consumption and related waste disposal costs. Fan is not included, must be sized to meet exhaust requirements.

Inline Fume & Vapor Scrubbers

Centrifugal Fans

Laboratory Ventilation Systems

Designed to offer the complete solution to laboratory ventilation concerns. Integrated components, blowers, fume scrubbers, and ducting are engineered together to provide a safe, effective, and efficient fume hood ventilation system. VAV controllers minimize the amount of conditioned air that is exhausted through the fume hood.

Laboratory Ventilation Recommendations

Proper placement and use of fume hoods and blowers are important laboratory ventilation requirements. HEMCO offers the following suggestions to help in your laboratory layout. Please feel free to contact HEMCO’s technical support team in order help with your laboratory needs.
