Chapter 6: Maintaining Your Vertical Clean Bench
Product Service 1-800-522-7658
Initial Certification
The Purifier Vertical Clean Bench has been certified at the factory
for an average downflow velocity of 40-55 fpm along with the
HEPA Filter Leak Test. The Purifier Vertical Clean Bench should
be certified for the proper downflow 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 Purifier Vertical Clean
Bench should be recertified at least annually. The certifier should
perform the minimum following tests:
•
Downflow 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)
