Asking for a friend
I'm having a hard time getting the right pressure for my paint gun. Here's my setup (in order)
-Small-ish compressor (but with proper piston pump and ~7CFM@90PSI output)
-Some regulator
-water/oil separator after the regulator
-quick connect
-20' 3/8" hose
-quick connect
-gun's regulator
-gun (Devilbiss GTI Millenium)
I have this kit : link
Here's what's puzzling me :
The gun manual is telling me I should use around ~20PSI. No I cannot, for the life of me, get it to run on the "green" zone on the regulator.
The gun's regulator seems to indicate the line pressure?! If I crank up the compressor's regulator to 100PSI, I see 100PSI. If I tune it down, to, lets say, 35PSI, then It seems it doesn't react fast enough and I don't get enough CFM. When I pull the trigger, the pressure, as expected, dips down but it's at 10-12 PSI.. aka, not enough
My understanding of what I should do :
1-Use the maximum pressure I can up to the gun's regulator
2-Use the gun regulator to set it to the recommended pressure
Problem is trying to do #2... the adjustment knob clearly works but I can't see which value I'm setting it at.
Anything I'm missing?
I'm thinking that perhaps something is interfering with the flow (water & oil separator? quick connect).... but the gauge on that gun's regulator is weird.
