I am running my Sanborn HVLP sprayer. Cup on the bottom. The big one from Menards.
Getting intermittent spray out of the tip. Its even as clockwork. ON OFF ON OFF ON OFF like it was set to a metronome. Problem remains when I dial the air pressure down or up. Though it seems to get more chaotic at very high pressure.
Yes, I’ve cleaned the F—- out of this thing multiple times now.
Yes, I’ve cleared the air vent hole on top of the cup
Yes, I’ve taken it apart and checked for clogs, damage, holes, etc.
Yes, I’ve tightened down the tip.
Yes, I’ve adjusted the flow control, fan control.
Yes, the siphon is clear.
Yes, there is enough fluid in the cup.
I’m testing it using Lacquer thinner as it evaps almost instantly, it’s cheap, and light weight (so material being too thick is not a factor).
I am out of ideas. It is really weird to me that the spray is so CONSISTENTLY inconsistent. On Off On Off. It’s like something is trying to catch up. I can even hear the siphon refilling and emptying itself when I turn the pressure down real low and the compressor isn’t ringing in my ears. Like it’s having trouble sucking up the media and keeping it steady.
Oh, and if you are wondering if its my compressor regulator, I have another one of the exact same gun, running off the same compressor, and no problems at all with pressure, consistency, etc.
