Chapter 5: Using Your Filtered Enclosure and Appropriate Application
• The HEPA filter will gradually accumulate airborne
particulate matter from the room and from work performed in
the enclosure. The rate of accumulation will depend upon the
cleanliness of the room air, the amount of time the enclosure is
operating, and the nature of work being done. With normal
usage, the HEPA filters will last two to five years before
requiring replacement.
• Each filtered enclosure is provided with a HEPA filter. For
powders and particulates follow the HEPA Filter Bag-In/Bag-
Out procedure in Chapter 6 for disposal instructions. For
biohazardous materials, follow the Decontamination
Procedure in Chapter 6 for disposal instructions.
Odor Control Carbon Filter
Applications (sold as an
accessory)
• Release of low concentrations of vapors effectively adsorbed
or treated in carbon based filters.
• Treatment of low-level carcinogens or suspected carcinogens.
(See Chemical Carcinogens in Chapter 5)
• Procedures that may have traditionally been done on the open
bench (low levels only).
• Odoriferous chemicals that are an unpleasant nuisance.
Other applications, not fitting the above guidelines, would be
better suited with the exhaust ducted to the outside. The exhaust
connection kit (See Chapter 3 and Chapter 7) can be added to the
XPert Filtered Balance System for ducting to the outside.
Additionally, the XPert Filtered Balance Station is factory
prepared to be connected to a remote blower, or house exhaust
system for ducting to the outside. Labconco also manufactures
fume hoods and Class II Biological Safety Cabinets for exhausting
to the outside. Consult Labconco product specialist for additional
information.
