HVLP spray gun air pressure question

[scherp69]

When the spec sheet says to use 10 PSI at the cap, what would that be on the gauge where the air line connects to the gun? I was told about 30, but want to make sure that's right before I spray tomorrow. Thanks.

Depends on a few things, but 30 is a nice round number. Play with the pressure on either side, you may find 30 is a fuzz to high. Make sure you have a moisture trap on the line. FWIW.

I see you are up in B.C. Definitely use a moisture filter and pay attention to the time of day you spray. Early in the morning and late evening could be significant temp differences if you are not in a booth.

Thanks guys. I usually had it about 25 PSI when I sprayed it earlier. Overall I'm happy with the way it turned out.

armourmark...yeah I waited until it was just after noon to spray it. It was in the mid 20's when I did it.
