14.5 sec and 15.5 sec fluid gun selection and settings

Postby Jimmiejoe » Sun Sep 03, 2017 8:06 pm

I have GAST 3HBB-19-M322 12v compressor for our mobile business.
CFM: Free air 2.4CFM, 2.0CFM@16psi, 1.95CFM@20psi.
Air hose is 35feet of 1/4" on a retractable reel.
I have measured the viscosity of the fluid using Zahn #2 and Zahn #1 cups.
Most of the fluids are 14.5sec in #2, and 26.5sec in #1.
I have one fluid that is giving me 15.5sec in #2.
Given this what is the correct model # of spray gun you recommend?
Is it easy to get different needle and cap configurations later if I need the for a different fluid?

Thank you for the airbrush information.
Do you have a spray gun recommendation to compliant the airbrush for larger surfaces?

Hey WOW! do we ever & it's the LPH80 this gun may be small in stature BUT, sprays like the big boys and only requires about 2 CFM @ 14 PSI to spray at its optimum -sound to good to be true? it's NOT!!
For the described performance I highly recommend the LPH80 - 124G computer number 4931 and includes 150ml aluminum cup and cover'

How small of an area can the LPH80 spray?
How small of an a out of fliud is required to spray?

Trying to understand from a fliud consumption perspective when to use the LPH80 vs the airbrush.

I have a spray range from the size of a cigarette burn to an car interior to a full size couch.

Given the information you have shared, both on viscositys & your air supply equipment - I stand by my first choice - because there are seven different air cap fluid nozzle combinations for the LPH80 - THERE IS EVEN AN OPTIONAL 2oz plastic cup. fluid nozzles sizes range from 0.4 to 1.2 Pattern sizes from a very small dot to about 6" Remember with these guns you are the boss these gun have a wide range of adjustments. I think if you get the right set up the LPH80 would be you gun of choice

What are the recommended setting to start from for these viscosities?
Does it change with fluid needle or air cap?

As a starting point, all guns would start in the full open position, that's full open on the fan and material settings and at the inlet pressure designated on the catalog page.Changing would be determined by you as the job dictates. I am sending those pages for you inspection Cheers, Hub

For the fan, full open mean a line not a circle correct?

Some guns & brushes are designed to have a round pattern So the standard of full open would also apply.

What filter mesh is recommended for each nozzle size to minimize clogging?

Is single filtering sufficent or is double filtering recommended?

190 micron filter mesh is the standard mesh for most automotive refinish material - water or solvent
