High Performance Features
The patented 1 XPert Nano Enclosure is 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 Labconco line of
enclosures so unique is the revolutionary way they direct air into and through the
contaminated air chamber. Labconco engineered them 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 ULPA 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 Nano Enclosure includes a true bag-in/bag-out ULPA filter disposal
system to protect the worker from contact with hazardous powders and
particulates. Users are encouraged to routinely check airflow with the use of the
airflow monitor.
