Gentlemen;

I picked up a used HVLP gun (jaguar SLP). It says it only needs 29 psi inlet pressure. Does that mean i set the gauge before it enters the gun at 29 psi, or does it mean 29 psi with the trigger pulled? Thanks for any info you can share.

Set the regulator on the wall to 60 or 70 PSI then attach the hose and pull the trigger then set the inlet pressure with air blowing through the gun.

What they mean is, with the Fan wide Open and the trigger pulled the inlet
air pressure gauge should read 29PSI.

This is a typical setting for a number of hvlp guns on the market, Its typically
the Max setting. Depending on the viscosity of the material your spraying
you can adjust the gun down from that point. I.E You do not need to
necessarily run the gun full trigger at 29psi inlet pressure. The idea is to
balance air pressure/Atomization/overspray and adjust the gun to meet
those goals !

The 29psi inlet pressure will give 10psi at the gun nozzle which conforms to the
HVLP Spec. Depending on your air supply and hose/couplers etc you may need to
have anywhere from 50 - 70psi at the wall to get the 29psi at the gun inlet.
