PSI For Spray Gun

[Championship White]

I have an ancient petrol air compressor which has a 3.5 HP Honda motor and 100 liter tank when I attached a HVLP gun and held the trigger at full the guage on the gun said 2 bar (29 PSI).

I'm looking into buying a couple of cheapy guns, one for water-based base-coat and one for 1k clear.

Should I be looking at LVLP guns? And what tip sizes? Any recommendations for around £50 per gun?

Your compressor would be producing 7 to 9cfm I would think,are you saying that it keeps the pressure at 2bar at the gun all the time the trigger is pulled back or does it drop off.

It keeps a steady 2 bar when trigger is fully depressed.

That means that it can keep up with whatever is the consumption of your hvlp gun,so if you know how much air your present gun uses it gives you a starting point to choose your new gun.

Thanks Eli, does that then mean I am spraying at 2 bar pressure, or to find that out do I take the 2 bar away from the maximum running pressure of the compressor?
