TYPES OF INSTALLATION
5/16”
1/4”
Only 43 PSI at gun inlet
25 feet of 1/4” I.D. hose causes
a drop of 17 PSI between the
air supply and the gun.
(NOT RECOMMENDED)
54 PSI at gun inlet
25 feet of 5/16” I.D. hose
causes a drop of 6 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
PRESSURE CUP HOOKUP
(Figure 1)
For fine finishing with limited
spraying. Air pressure for
atomization is regulated at extractor;
fluid pressure at cup regulator.
Pressure cup is also available less
regulator.
PRESSURE TANK HOOKUP
(Figure 2)
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 3)
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 4)
For heavy production spraying.
Air pressure atomization regulated
at separator filter. 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.
Separator filter is important.
Achieving a fine spray finish without the use of a good separator filter is virtually impossible.
A regulator / separator filter 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 Separator Filter / Regulator. See your local
distributor for other models.
