HVLP Guns
An HVLP gun is a high transfer efficiency gun
that limits the air pressure at the air cap to
10 psi (0.07 MPa, 0.7 bar) maximum. In some
areas, an HVLP gun is required for compliance
with environmental standards. See the Air Cap
chart, page 7, for maximum inlet pressures.
Conventional Guns
An airspray gun has excellent atomization and
high production rates typically with some

Compliant Guns
A compliant gun is a high transfer efficiency
gun that has been tested to have a transfer
efficiency greater than or equal to HVLP guns.
In addition, the compliant air cap consumes
much less air than the HVLP air cap. Graco
compliant guns have no restrictions on air cap
pressures. See the Air Cap chart, page 7, for
maximum inlet pressures.
