TYPES OF INSTALLATION
2
5/16"
1/4"
Only 34 PSI at gun inlet
25 feet of 1/4" I.D. hose causes
a drop of 26 PSI between the
air supply and the gun.
(NOT RECOMMENDED)
48 PSI at gun inlet
25 feet of 5/16" I.D. hose
causes a drop of 12 PSI
between the air supply
and the gun. For this reason
Binks recommends the use
of 5/16" hose.
(RECOMMENDED)
With 60 psi applied at air supply
CONNECTING GUN TO
“PRESSURE ASSISTED” 1 QT. CUP
(Figure 1)
The stainless steel pressure-assisted
1-quart cup, 80-272, utilizes a low
pressure air bleed port on the gun head to
slightly pressurize the cup and provide
fluid flow to the nozzle. A check valve
prevents the cup from depressurizing
when the gun trigger is released and
airflow stops.
To connect the gun to the cup, remove the
plug (35) in the gun head and install the
hose barb fitting provided with cup assem-
bly. Attach cup assembly to 3/8" NPS fluid
inlet connection and firmly tighten. The
siphon tube should be angled toward the
front of the gun, i.e. under the nozzles,
and the pressure hose in the cup lid posi-
tioned to the left of the trigger. Connect
check valve assembly hose from bard fit-
ting on gun head to check valve inlet fit-
ting on cup cover. Make sure the check
valve is connected so the air comes from
the gun, through the check valve, into
the cup.
Air pressure for atomization is regulated
at the extractor. The flow of the fluid is
adjusted by the fluid valve control
knob on gun, viscosity of paint and
air pressure.
PRESSURE CUP HOOKUP
(Figure 2)
For fine finishing with limited spraying.
Air pressure for atomization is regulated
at extractor; fluid pressure at cup regula-
tor. pressure cup is also available less
regulator.
PRESSURE TANK HOOKUP
(Figure 3)
For medium production spraying (single
regulator). Air pressure for atomization is
regulated at extractor, fluid pressure at
tank regulator.
PRESSURE TANK WITH
2 REGULATORS (Figure 4)
The pressure to the tank is regulated by
the first regulator. The pressure for
atomization is regulated by the second
regulator.
PRESSURE CIRCULATING
HOOKUP (Figure 5)
For heavy production spraying. Air
pressure atomization regulated at extractor.
Fluid pressure regulated at fluid regulator.
AIR PRESSURE
Atomizing pressure must be set
properly to allow for the drop in
air pressure between the regulator
and the spray gun.
Binks oil and water extractor is important
.
Achieving a fine spray finish without the use of a good oil and water extractor is virtually
impossible.
A Binks regulator/ extractor serves a double purpose. It eliminates blistering and spotting by
keeping air free of oil and water, and it gives precise air pressure control at the gun.
Binks recommends using the HFRL-508 oil and water extractor / regulator.
