OPERATING INSTRUCTIONS
(Internal Mix Air Nozzle Application)
The internal mix air nozzle accomplishes atomization by
mixing the air and fluid within the air nozzle. Note: The
steps are the same as with external mix nozzles except
the air and fluid pressure settings are different.
1. Close air adjusting valve by turning clockwise.
2. Set air pressure at oil and water extractor (transformer)
to approximately 45 PSI.
3. Open air adjusting valve and allow air to enter the gun.
4. Set fluid pressure at 20 lbs. and adjust higher or lower
until desired atomization is effected. Air pressure
should be alternately adjusted.

ly 10 PSI.
