Connecting the Electrical Supply
A standard duplex receptacle should be nearby for connecting the FilterMate
Portable Exhauster, airflow monitor and accessories. Please review Chapter 2 for
electrical prerequisites.
ALL WIRING FOR THE BUILDING DUPLEX OUTLETS SHOULD BE
PERFORMED BY A LICENSED ELECTRICIAN AND CONFORM TO
ALL LOCAL CODES.
Sealing the Vented Enclosure to the Work Surface
When the enclosure has been set in place, ducted 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 enclosure to the work surface.
Validating the Vented Enclosure
The exhaust damper ductwork, exhaust blower or FilterMate gives you the
flexibility to change the airflow at the sash opening of your enclosure. To
determine the actual face velocity at the sash opening, airflow velocity readings
will need to be taken. This should be done across the sash opening of the
enclosure in accordance with the Industrial Ventilation Manual. (See Appendix D)
The “average face velocity” is achieved by taking readings in two rows across the
enclosure with the readings 6" from the ends and evenly spaced every 12"; the first
row is 3" down from the upper sash foil and the second row is 3" up from the work
surface. Labconco recommends an average face velocity at the sash opening of 60
to 100 feet per minute for high performance XPert and Protector XVS enclosures.
Refer to Chapter 2 for proper airflow volumes for your particular model.
Your XPert or XVS enclosure has been tested at the factory per ASHRAE 110-
1995. All enclosures achieve an “as manufactured rating” of less than 0.05 part
per million (ppm) at 4 liters per minute (lpm); AM <0.05 (Consult Labconco for
individual ratings). For “field use” ASHRAE testing contact Labconco for a
certified on-site contractor. For additional validation, Labconco had independent
testing performed to validate the enclosures for
sodium naproxen powder containment. Labconco also had independent ASHRAE
testing performed to validate the enclosures for gas containment. For copies of
these independent validation reports, contact Labconco Customer Service.
NOTE: Face velocity profiles and smoke testing should be performed
frequently per your organizations quality system to ensure safe performance
