HEPA Filter Applications,
Suitability and Guidelines
•
Procedures traditionally performed on an open bench where a
clean Class 5 air environment is now required.
•
The HEPA filtered enclosure provides product protection from
particulate matter. Because air from the Clean Bench enters
from the room during operation, this enclosure should only be
used for operations requiring sample protection from
environmental contamination.
•
HEPA filters are only effective for entrapment of particulate
matter. The surface of the HEPA filter is fragile and should
not be touched. Care must be taken to avoid puncturing the
HEPA filter during installation. If you suspect that a HEPA
filter has been damaged, DO NOT use the enclosure. See
Chapter 6 for Replacing the HEPA Filter.
•
The HEPA filter will gradually accumulate airborne
particulate matter from the room. The rate of accumulation
will depend upon the cleanliness of the room air, and the
amount of time the enclosure is operating. With normal
usage, the HEPA filters will last two to five years before
requiring replacement.
