12. Vibration-Isolated Motorized Impeller has vibration isolation supports,
which eliminates transfer of vibration to the work surface. This is
extremely useful in weighing operations with precision balances. The
impeller wheel is also dynamically balanced. See Figure 4-2.
13. Speed Control regulates the speed of the motorized impeller and is used
by the certifier to validate and adjust the inflow velocity. Located behind
the front panel. See Figure 4-2.
14. Space-Saving Design increases effective laboratory workspace, because
the impeller and HEPA filter are contained within the enclosure, a separate
filtered blower module is not required. See Figure 4-1
15. Fluorescent Lamp is located above the work area, out of contact with
contaminated air. A safety glass window beneath the lamp distributes the
light evenly across the work surface. See Figure 4-1.
16. Filter System Pressure Gauge indicates the total system pressure across
the HEPA filter and pressurized plenum to help predict HEPA filter
loading. See Figure 4-1.
17. Filter Clamping Bolt evenly seals the HEPA filter to the frame of the
enclosure. See Figure 4-1 and 4-2.
18. Sash. The sash is constructed of 1/4 inch tempered safety glass. It pivots
up for loading and cleaning. See Figure 4-1
19. Control Panel. The control panel, which is located above the sash,
contains the filter system pressure gauge, control switches and the
electronics. See Figure 4-1.
20. HEPA (High Efficiency Particulate Air) Filter is rated to remove
99.99% of all particles 0.3 micron in size. See Figure 4-2. HEPA filters
listed in Chapter 3 and 7.
21. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the
control panel.
22. Accessory Work Surface (not shown) is contoured to fit the dimensions of
the enclosures to contain spills.
23. XPert Filtered Balance Station Exhaust Collar (Not shown) provides a
6" (2', 3' and 4') or 10" (5' and 6') diameter transition to a remote blower or
house exhaust system. See Figure 3-2 in Chapter 3.
24. Accessory Odor Control Carbon Filters are available for nuisance odor
control. Accessory carbon filters are designed to remove trace amounts of
noxious fumes; capacity is not adequate to remove continuous fume
generation. The carbon filters are supported above the HEPA filter and the
gasket side is down and compressed by the weight of the carbon filter.
Carbon filters are listed in Chapter 3 and 7. See Figure 4-2.
25. Accessory Thimble Exhaust Connection is available to duct integral
blower models including the XPert Filtered Balance System to the outside.
The Thimble Exhaust Connection allows the operator additional protection
