Types Of Installation; Air Pressure - Binks TROPHY HVLP Serie Manual De Servicio

EN
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.
GRAVITY FEED HOOKUP
On gravity-feed spray guns the cup is located above the gun. The force of gravity pushes the fluid into the gun.
Advantages: this method offers quick color changes and convenience on small jobs or touch-up applications. Gravity
spray guns are able to use all of the coating—reducing waste.

AIR PRESSURE

Atomizing pressure must be set properly to allow for the drop in air pressure
between the regulator and the spray gun.
WITH 60 PSI APPLIED AT AIR SUPPLY
5/16"
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.

An 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 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
1/4"
control at the gun.
Use DeVilbiss oil
and water extractors
and regulators.
