XPert Filtered Balance System and XPert Filtered Balance Station
are designed to meet the needs of the laboratory scientist, and provide superior
containment while conserving energy at OSHA approved “low flow” velocities as
low as 60 feet per minute. The filtered enclosures have been tested to effectively
contain toxic and noxious materials when properly installed and operated. What
makes the filtered enclosures so unique is the revolutionary way they direct air into
and through the contaminated air chamber. Labconco engineered the filtered
enclosures to minimize the effects of turbulence. The containment-enhancing and
aerodynamic designs of the upper sash foil, side air foils, lower air foil, upper
dilution air supply, and rear perforated baffle all work in concert to produce
horizontal airflow patterns that significantly reduce powder, chemical and
particulate concentrations through the work area.
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 XPert Filtered Balance System and XPert Filtered Balance Station include a
true bag-in/bag-out HEPA filter disposal system to protect the worker from contact
with hazardous powders and particulates. Users of both products are encouraged
to routinely check airflow with the use of the airflow monitor.
