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)

Fluorescent Light Replacement
