The Iso-Flo system houses a pneumatically operated shuttle, pump,
valves, and interconnecting lines. When the spray device is triggered,
the shuttle opens and breaks the fluid connection to the supply. The
pump pressurizes the coating material and delivers it to the spray device.
The fluid path is electrostatically charged only from the shuttle to the
spray device. When the spray device trigger is released, the shuttle
closes and grounds the fluid path. Coating material flows through the
shuttle couplings to refill the pump.
To prevent electrical shock, an interlock valve closes the shuttle and
grounds the fluid path if the cabinet door is opened while the operator is
spraying coating material. An air-operated fluid pressure regulator and
an air pressure regulator inside the cabinet control the fluid pressure to
the spray device.
Figure 2-1 illustrates the components listed in the table. Table 2-1 lists
the components and describes their function. Numbers in the table
correspond to the callouts in the illustration.
