individual ratings). For “field use” ASHRAE testing contact Labconco for a certified on-site contractor. For particulate powder validation, Labconco had containment testing performed to validate the enclosures for sodium naproxen powders. The XPert HEPA filtered 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 that the XPert HEPA Filtered Enclosures provide a safe working environment. Labconco also performed extensive ASHRAE testing to validate the enclosures for gas containment. For copies of these validation reports, contact Labconco Customer Service.

The XPert enclosures were also subjected to Biological Containment testing, using a modified Personnel Protection Test, as described in NSF/ANSI Standard Number 49. An aerosol challenge of approximately 5 x 108 spores of Bacillus subtilus var Niger were released in the enclosure and appropriate air sampling equipment established the number of spores that escaped through the sash opening. Each size enclosure was tested three times. All three sizes of the enclosure were tested at 75 FPM inflow and typically 1 or less than one spore escaped from the enclosure during each of the tests.

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.
