Performance Features
The Protector XStream High Performance Laboratory Hood 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 50-60 feet
per minute. The Protector XStream laboratory fume hood has been designed to
effectively contain toxic, noxious, or other harmful materials when properly
installed. What makes the Protector XStream so unique is the revolutionary way
it directs air into and through the contaminated air chamber. Labconco
engineered the Protector XStream to minimize the effects of turbulence. The
innovative and aerodynamic designs of the sash handle, air foil, upper dilution air
supply, and rear downflow baffle all work in concert to produce horizontal
airflow patterns that significantly reduce chemical concentrations through the
work area. Depending on sash position, air turbulence, vortexing and “the roll”
frequently observed during fume hood smoke tests are virtually eliminated by the
Protector XStream high performance system. Optional A-Style Combination Sash
models are also available upon request. The hood features a by-pass airflow
design that allows the hood face velocity to remain relatively stable as the sash is
closed. Airflow is diverted behind the front panel and under the air foil to help
control fluctuations in face velocity, which occur as the sash is closed.
1. Unique sash provides maximum visibility of 37.5" high while
conserving energy by limiting sash travel to 28". Vertical-rising sash
may be raised from a closed to 28" operating height. Exhaust volume, and
blower sizing is based on the 18" height to maximize energy usage. Sash
stops are included to limit sash height to 18" and reduce energy usage.
