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 noz-
zle. 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 (34) in the gun head and install
the hose barb fitting provided with cup
assembly. 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 positioned to the left of the trigger.
Connect check valve assembly hose from
barb fitting on gun head to check valve
inlet fitting 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 pres-
sure atomization regulated at extractor.
Fluid pressure regulated at fluid regulator.
AIR PRESSURE
Atomizing pressure must be set prop-
erly to allow for the drop in air pres-
sure 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 Model HFRL-508 Oil and Water Extractor / Regulator. See your
local distributor for other models.
