The Purifier Enclosures were also subjected to an industrial hygiene air-monitoring
study to confirm the performance of the enclosure for powders. The Purifier
Enclosures demonstrated excellent containment when used by an operator using
excellent technique and good containment when used by an operator using
marginal technique. While no enclosure can compensate for improper technique,
these tests confirm the Purifier Enclosures provide a safe working environment.
NOTE: Face velocity profiles and smoke testing should be
performed frequently per your organization’s quality system to
ensure safe performance.
Sealing the Filtered Enclosure to the
Work Surface
When the filtered enclosure has been set in place, ducted, (if necessary), and wired,
it may be sealed at the work surface to prevent spilled materials from collecting
under the walls. A bead of silicone sealant is recommended to seal the filtered
enclosure to the work surface.
