Graco Fluid Transfer Technology
* Using ASTM standard - 50% is the maximum transfer efficiency due to conveyor methods of spraying. EN standard sprays on a flat panel.
**Pressure measured at the gun inlet under flow conditions. For best results, use the lowest fluid and air pressure for the job by determining flow rate and viscosity.
*** SCFM requirements are shown for gun only, and are averages. Pump air consumption is approximately 1.5 scfm for diaphragm pumps, and 2-5 scfm for piston pumps.
Note: typical air compressor sizing is 1 HP per 4 scfm.

DEFINITIONS
AIR SPRAY/CONVENTIONAL
The most widely used finishing method. Referred to as an
automotive finish or Class A finish. Easy to use, flexible and
provides the finest finish quality and the lowest transfer efficiency.
COMPLIANT
A controlled air spray technology that reduces bounceback
and overspray. The finish quality is compatible to air spray, air
consumption is lower than HVLP and the spray rates are higher
than HVLP.
HVLP
A controlled, compliant air spray technology that reduces bounceback and overspray. Finish quality is comparable to air spray,
however atomization is generally coarser and spray rates are lower.
AA Series Spray Pattern
Air Assist
Airless
XTR Spray Pattern
AIR ASSIST
Combines the hydraulic atomization of airless with the atomization
of air spray. Ideal for many finishing and coating applications, air
assist offers high production levels and a relatively smooth finish perfect for wood furniture topcoats or fabricated metal parts.
AIRLESS
Directs fluid under high pressure through a controlled orifice to
accomplish airless atomization. Ideal for quickly applying high
volumes of coatings to large surfaces. Most often used to apply
protective, rather than decorative coatings.
