High Performance Features
The patented
1 Protector Work Stations 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
enclosures have been tested to effectively contain toxic and noxious materials
when properly installed and operated. What makes the enclosures so unique is the
revolutionary way they direct air into and through the contaminated air chamber.
Labconco engineered the 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 Protector Work Station with integral blower is designed only for low-level
concentrations for use with carbon filters and exhausting to the room. The
Protector Work Station for use with a remote blower is designed for high-level
concentrations for exhausting to the outside.
