HVLP Guns
An HVLP gun is a high transfer efficiency gun which lim-
its the air pressure at the aircap to 10 psi maximum. In
some areas, an HVLP gun is required for compliance
with environmental standards.
Air Caps
The chart below lists the air caps available for pressure
feed, gravity, and siphon feed guns.

Compliant Guns
A compliant gun is a high transfer efficiency gun which
has been tested to have a transfer efficiency greater
than or equal to HVLP guns. The Graco compliant guns
have no restrictions on aircap pressures, but the gun
inlet pressure must remain under 29 psi (21 MPa 2.1
bar) to remain in compliance.
Airspray Guns
Excellent atomization and high production rates typically
with some reduction in transfer efficiency.
