HVLP cap pressure ?

[VenturaII]

How do you determine what the cap pressure is on an HVLP gun?

For my Binks gun, I got one of their special caps with a built-in gauge. But it really should just be needed to verify the input regulator/cap pressure relationship. The setup guide for your gun probably has a recommended pressure and line size to obtain the desired cap pressure. Of course my cheap Harbor Freight gun had no such info available. I guess you just experiment till you get your desired results.

this is basically what you get for testing a gun, it's offered by the manufacturer and is gun model specific.
