Chapter 4: Performance Features and Safety Precautions
1. Aerodynamic Lower Air Foil allows air to sweep the
work surface and promote ISO Class 5 air conditions inside
the enclosure. See Figure 4-1.
2. Ergonomic Slope of 10 degrees provides maximum
visibility and comfort, reduces glare, thereby minimizing
operator fatigue. See Figure 4-1.
3. Internal Depth of 25" provides necessary depth to work
inside the enclosure. See Figure 4-1.
4. Safety Glass Sash with Spring-Loaded Latch has a
wiping seal and features a spring-loaded latch to secure
sash open for loading and cleaning. The sash must be
down for normal operation. See Figure 4-1.
5. Utility Ports with Iris allows electrical cords and data
cords to pass through the back of enclosure without leaving
a large hole. The enclosure ships with solid plugs. Iris
plugs are included with the User’s Manual. See Figure 4-1
and 4-2.
6. Optional Guardian™ Airflow Monitor continuously
monitors airflow. An audio/visual alarm alerts the user to
low airflow conditions. The Guardian™ Airflow Monitor
is an available option on all Purifier Filtered PCR
Enclosure models. See Figure 4-1 and 4-2.
7. Inherently Safe Impeller has a negative pressure plenum
that surrounds the positive pressure impeller so that if a
leak should occur, the unfiltered air is captured and
refiltered. See Figure 4-2.
8. Speed Control regulates the speed of the motorized
impeller and is used by the certifier to validate and adjust
the downflow velocity. Located behind the front panel.
See Figures 4-1 and 4-2.
9. Fluorescent Lamp is located above the work area, out of
contact with the clean air. A safety glass window beneath
the lamp distributes the light evenly across the work
surface. See Figure 4-1.
10. Filter Pressure Gauge indicates the pressure across the
HEPA filter to help predict HEPA filter loading. See
Figure 4-1.
