High Performance Features:
The patented* Purifier HEPA Filtered Enclosure and Purifier
Class I Enclosure are designed to meet the needs of the
laboratory scientist, and provide superior containment while
operating at velocities between 75-105 feet per minute. The
filtered enclosures have been tested to effectively contain toxic,
noxious, and biohazardous 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 biological material concentrations through the
work area.
