Chapter 4: High Performance Features and Safety

Monitor also displays a face velocity value, provides an RS232 output, a night setback mode and several auxiliary relay ports. Both airflow monitors are available options on all XPert models. See Figure 4-1 and 4-2.

11.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.

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.
