Initial Certification
The TXE has been certified at the factory for an inflow velocity of 90±10 fpm
along with the HEPA Filter Leak Test. The TXE 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)
