Air Air Requirements
• Compressed Compressed air Compressed air air supply supply pressure: supply
(0.6–0.7 MPa, 6.0-7.0 bar).
Air hoses: hoses: use grounded hoses that are correctly
• Air Air hoses:
sized for your system.
• Air Air regulator Air regulator regulator and and bleed-type and bleed-type shutoff bleed-type
in each air line to fluid supply equipment. Install
an additional shutoff valve upstream of all air line
accessories to isolate them for servicing.
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.
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 Line Filter Filter for for System System Control
• Air Air Line Filter for System
air regulator/filter 17M842 to provide clean and dry
air to system control solenoids.
Air Line Line Filter Filter for for Atomizing Atomizing Air:
• Air Air Line Filter for Atomizing
to filter oil and water out of the air supply and help
avoid paint contamination.

Air Connections Connections
Air Air Connections
1. Tighten all system air and fluid line connections
as they may have loosened during shipment.
2. Connect the main air supply line to air
regulator/filter 17M842, and then to the main air
inlet (136). This air line supplies the solenoids,
valves, and pumps. Do not use this line to supply
the gun's atomizing air.
3. Connect a separate, separate, dedicated, separate,
line to the air inlet of the gun atomizing air.
