Clean-Aire Filtration Systems
HEMCO Clean-Aire Filtration Systems are specifically designed to remove particulate and/or fumes from the exhaust air stream of
a laboratory UniFlow fume hood. The filter systems effectively clean the air of contaminants prior to discharging into the atmosphere
to meet EPA regulations. Also, in some cases, depending on the contaminant, the exhaust can re-circulate back to the lab.
HEMCO filtration systems are offered as a Clean-Aire Pak or Clean-Aire Bag-in Bag-out Filter Pak. A HEPA filter is provided to
collect particulate, a carbon filter is provided to adsorb fumes and odors, or a combination of the two filters can be assembled as
one module.
|
| |
Clean-Aire HEPA Filter Pak
The HEPA Filter Pak is designed to collect airborne particulate from the exhaust. 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 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.

Clean-Aire 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

Clean-Aire Carbon Filter Pak
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.

Clean-Aire Carbon Filter Bag in Bag out System
Filter housing is fabricated of type-304 stainless steel and includes
(1) Carbon Filter Absorber, (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
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: 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.

Air Monitor Sampling Kit
Kit allows you to sample from a carbon filter system to determine
if there has been contaminant break through. The air monitor
system includes a non-sparking gas sampling pump, instruction
sheet, rubber tube holder with filter, lubricant, piston gasket and
handy carrying case. Detector tubes are not included.

Fume & Vapor Clean Aire 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.
|
|
|
|
| |
Remote Recirculation Tank & Pump
Can be supplied for installations where the scrubber is located
outdoors and the possibility of freezing exists.
|
|
|
|
| |
pH Control Package
Allows precise control over effluent quality and provides neutralization
of contaminants. The pH control system consists
of a weather-tight, corrosion-proof enclosure containing an
analyzer, pre-wired chemical feed pump, weather-protected
terminal block, clear PVC face plate and external chemicalfeed
connection. Enclosure can be mounted on any vertical
surface. A heavy-duty industrial probe with a 10 ft. lead wire
is supplied, along with two 10 ft. lengths of vinyl tubing to
connect the feed pump.
