HEPA Filter System

HEPA Filter Bag in Bag out 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

Carbon Filter System

Carbon 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.

Fume & Vapor Scrubbers Scrubber systems offer high efficiency and minimal maintenance on meeting pollution control requirements.
	Clean Aire Scrubber 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.
