Autopress Pressure Filter (continued)

The autopress implements motor starters, primary feed disconnect, relays, Allen-Bradley programmable controller, intrinsic safety barriers, solenoids, Allen-Bradley PanelView operator interface, and other auxiliary control equipment.

The panel is purged with a Bebco Z-Purge unit and is suitable for use in Class I, Division 2, Group C and D hazardous environments.  This purge unit is clearly visible from the front of the Panel as it is mounted on the right side facing forward.  A gauge indicating the safe and unsafe pressure range for the enclosure is visible to the operator.  The unit is capable of using either instrument quality compressed air or nitrogen to provide suitable purge and volume exchanges of the enclosure.
