Air Supply - Graco ProMix PD2K Installation Manual

Air Supply

Air Requirements
• Compressed air supply pressure: 85-100 psi
(0.6–0.7 MPa, 6.0-7.0 bar).
• Air hoses: use grounded hoses that are correctly
sized for your system.
Trapped air can cause a pump or dispense
valve to cycle unexpectedly, which could result
in serious injury from splashing or moving parts.
Use bleed-type shutoff valves.
• Air regulator and bleed-type shutoff valve: include
in each air line to fluid supply equipment. Install
an additional shutoff valve upstream of all air line
accessories to isolate them for servicing.

To reduce the risk of fire and explosion if using
a Graco electrostatic gun, a shutoff valve must
be installed in the gun air line to shutoff the
atomizing and turbine air to the gun. Contact
your Graco distributor for information on air
shutoff valves for electrostatic applications.
• Air line filter: to filter oil and water out of the air
supply and help avoid paint contamination and
clogged solenoids. See
air filtration requirements.
