Air Pressure; Gun Handling; Air Supply - Binks 2100 Manual De Instrucciones

Atomizing pressure must be set properly to allow for the drop
in air pressure between the regulator and the spray gun.

DEVILBISS OIL AND WATER SEPARATOR IS IMPORTANT
Achieving a fine spray finish without the use of a
good oil and water extractor is virtually impossible.
A DeVilbiss regulator / separator serves a double
purpose. It eliminates blistering and spotting by
keeping air free of oil and water, and it gives pre-
cise air pressure control at the gun.
The first requirement for a good resultant finish is
the proper handling of the gun. The gun should be
held perpendicular to the surface being covered and
moved parallel with it. The stroke should be started
before the trigger is pulled and the trigger should
be released before the stroke is ended. This gives
accurate control of the gun and material.
The distance between gun and surface should be 6
to 12 inches depending on material and atomizing
pressure. The material deposited should always be
even and wet. Lap each stroke over the preceding
stroke to obtain a uniform finish.
It is extremely poor practice to mount the oil and
water extractor on or even near the compressor unit.
The temperature of the air is greatly increased as it
passes through the compressor and this compressed
air must be cooled before the moisture in it will
condense. If the air from the compressor is still
warm when it passes through the oil and water
extractor, moisture will not be effectively removed,
but will remain in suspension. Then, when the air
cools in the hose beyond the extractor, the moisture
will condense into drops of water and cause trou-
ble.
Air lines must be properly drained
Pitch all air lines back towards the compressor so
that condensed moisture will flow back into the air
receiver where it can be removed by opening a
drain. Every low point on an air line acts as a water
trap. Such points should be fitted with an easily
accessible drain. See diagram.

Binks recommends using Model HFRL-508 Oil and
Water Separator / Regulator. See your local distributor
for other models.

To reduce overspray and obtain maximum efficiency, always
spray with the lowest possible atomizing air pressure.

AIR SUPPLy

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)
Coating should be even
6 to 12 inches
and wet when spraying
