Chapter 4: High Performance Features and Safety
These concentrations of materials are predominantly removed
on the “first pass” of airflow through the chamber resulting in
high performance containment.
The plenum and the HEPA filter are jacketed by negative
pressure. Should a leak occur in the filter gasket or the
plenum, the contaminated air is recaptured and refiltered.
The Purifier Class I Enclosure and Purifier HEPA Filtered
Enclosure have an access port located behind the front panel.
For HEPA filter removal in biohazardous applications on
Purifier enclosures, the HEPA filter will require
decontamination before removal. Users of all equipment are
encouraged to routinely check airflow or purchase a model
with an airflow monitor.
