Performance Features:
The Protector XL Laboratory Hood is designed to meet the needs of the
laboratory scientist at OSHA approved velocities as low as 60 feet per minute.
The laboratory fume hood has been designed to effectively contain toxic, noxious,
or other harmful materials when properly installed. A fully featured by-pass hood
with baffle and air foil, this hood maintains safe airflow. Optional energy saving
A-Style Combination Sash models are also available. The hood features 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. The fume hood
features a containment-enhancing sash handle. Optional sash stops are
available to limit sash height and reduce energy usage.
2. By-pass airflow design ensures relatively stable face velocities.
3. Large usable interior work depth and interior height of 48" provides
ample working space.
4. Baffle (not shown) directs airflow to the rear of the interior to provide
efficient airflow. The baffle may be removed for cleaning purposes only.
The Opti-Zone™ baffle provides optimized airflow and face velocity
profile for optimal containment.
5. Exterior access cover plates are removable for easy access to plumbing
valves and sash adjustment hardware when access through the sides is not
available.
