Auto Drain
When the bowl is pressurized, the piston travels down
against the spring and closes the drain opening. When
the bowl is depressurized (i.e., overnight when system is
shut down), the spring lifts the piston from the seal,
allowing the bowl to drain.
Coalescer Pressure Drop
Indicator
The differential pressure drop indicator provides early
detection of a clogged coalescing filter element. As the
filter element becomes clogged, the red indicator starts
to rise while air is flowing through the unit. When the
pressure drop across the element reaches 10-12 psi
(69-83 kPa, 0.7-0.8 bar), the red indicator will be in full
view, and the element should be replaced. Failure to
replace the element when the pressure drop exceeds 10
psi (69 kPa, 0.7 bar) will affect your air quality and tool
efficiency.
Pressure Relief Procedure
The following is a basic pressure relief procedure. Be
sure to follow the specific pressure relief procedure in
your spray gun and/or fluid supply equipment manuals.
1. Close the main air shut-off valve.
2. Trigger the gun or dispense valve and open any
drain valves to relieve pressure.
WARNING
Do not exceed the Maximum Incoming Air Pressure
of the equipment. Over pressurizing can cause com-
ponent rupture and serious injury.
You can push the piston stem on the bottom of the
bowl to manually drain it.
WARNING
To avoid injury, relieve air and fluid pressure before
checking, cleaning, or repairing the equipment.
