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 Vertical Clean
Bench 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 Figure 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.
11. Filter Clamping Bolt evenly seals the HEPA filter to the frame of the
enclosure. See Figure 4-1 and 4-2.
12. Control Panel. The control panel, which is located above the sash,
contains the filter pressure gauge, control switches and electronics. See
Figure 4-1.
13. HEPA (High Efficiency Particulate Air) Filter is rated to remove
99.99% of all particles 0.3 micron in size. See Figure 4-2.
14. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the
control panel.
