Installation of Carbon Filters for Room
Exhaust
For carbon filter installation, first unthread the knobs on the perforated baffle
located inside the enclosure in the upper corners. Use caution when slowly
lowering the perforated baffle. See Figure 6-4 in Chapter 6 for location of the
perforated baffle and knobs. See the following list of available carbon filters
below and in Chapter 7. All carbon filters are simply installed with the gasket side
on the downstream exhaust side. Install the correct carbon filter for the application
and call Labconco for assistance. Two carbon filters must be installed behind the
perforated baffle. These two filters provide additional capacity and mixing of the
air stream for proper performance. If using both a formaldehyde filter and organic
vapor filter at the same time you must place the formaldehyde filter downstream of
the organic vapor filter. (With the perforated baffle tilted down, the formaldehyde
filter is on top of the organic vapor filter.)
Filter Type Appropriate Use
Organic Vapor
Activated Carbon
3924200
10.5 lbs.
Adsorbs organic compounds designated by NIOSH
guidelines as acceptable for use with chemical
cartridge-type respirators. Concentrations in the
enclosure’s work area must not exceed the IDLH for
the chemical and the exhaust from the enclosure must
be perfectly monitored not to exceed the TWA.
Formaldehyde
(Formalin)
3924201
13.3 lbs.
Formaldehyde requires the use of an impregnated
carbon. Concentrations in the enclosure’s work area
must not exceed the IDLH for the chemical and the
exhaust from the enclosure must not exceed the TWA.
Ammonia and
Amines
3924202
15.2 lbs.
Treats ammonia, low molecular weight amines and
other bases designated by NIOSH as acceptable for use
with ammonia cartridge type respirators. Requires the
use of an impregnated carbon. Concentrations in the
enclosure’s work area must not exceed the IDLH for
the chemical and the exhaust from the enclosure must
not exceed the TWA.
Important: Carbon filters do not provide any particulate
protection, but provide odor control for low level
concentrations below OSHA recommended time weighted
averages.
