PERFORMANCE FEATURES
AND SAFETY PRECAUTIONS
The Purifier Vertical Clean Bench is designed to provide product protection only
from airborne particulate matter. During operation, room air is drawn from the top
and filtered by the HEPA filter providing Class 5 conditions inside the enclosure.
The Purifier Vertical Clean Bench delivers Class 5 air conditions when operating
at downflow velocities of 30 to 65 feet per minute. The HEPA filter is jacketed by
positive pressure preventing contaminated air inside the enclosure and ensuring
Class 5 air conditions inside the enclosure.
The Purifier Vertical Clean Bench HEPA filter is located behind the front panel.
Users are encouraged to routinely check airflow to satisfy Class 5 air conditions
inside the enclosure or purchase a model with an airflow monitor. For additional
surface decontamination inside the enclosure, users are encouraged to use the
model with the internal UV light and UV sash closure.
