Initial Certification
The filtered enclosure has been certified at the factory for an inflow velocity of
90±10 fpm along with the HEPA Filter Leak Test. The filtered enclosure should
be certified for the proper inflow velocity required by your Safety Officer. It is
also a conservative recommendation to perform the HEPA Filter Leak Test again
should there be any damage caused during transport.
Re-Certification
Under normal operating conditions, the enclosure should be recertified at least
annually if serviced. The certifier should perform the following tests.
Inflow Velocity Test
HEPA Filter Leak Test
In addition, the following tests should also be performed at the user’s discretion:
Measure of Line Voltage and Current
Smoke Test to determine proper airflow patterns
Lighting Intensity Test (when appropriate)
Noise Level Test (when appropriate)
Vibration Test (when appropriate)
