harris two stage 92-50 propane regulator to use as a HVLP regulator

admin

is there any reason i cant use this to regulate air flow into my HVLP paint guns?  and totally abandon it as a propane regulator? the high side pressure gauge is greater then the out put of my compressor.i am thinking this would give me a really nice flow of regulated air and since it was a two stage it would be steady even if the compressor cycled it self.am i crazy or would this work?  thks bobbobs77vet/37ford4drEastwood digital TIG200HH190Lincoln Invertec 155sLincoln weldpak 100sears/craftsman (lincoln) 50a 240v buzz boxO/A rig Harris gaugesnexion cut 50 dxchicago electric (HF) 240v spot welder

Reply:I'm not sure of the specs of a 92-50 or the HVLP gun, but when I think about the volume of oxygen blast that a typical regulator can deliver  (enough to knock the operator in the nose with a torch, if he isn't ready for it)  with just a 200psi inlet pressure, I can't imagine that it wouldn't be enough flow for a paint gun. Most  common size gas regulators can easily work in the 1500 SCFH range. But again I'm not sure about the 92-50's specs, or the HVLP gun's requirements, or available inlet pressure. Strictly by the appearance,  to me,  the flow capacity of a typical fuel-gas regulator looks to be a lot greater than that of a typical body-shop spray regulator. I'd say check the charts. My hunch is it'll work.FWIW I have some common model of gaugeless Harris regulator that supplies adequate CO2 flow to operate an an air impact wrench - no problem. I'll check the model # when I get a chance.Good LuckLast edited by denrep; 10-03-2012 at 03:44 PM.
Reply:thks  for the idea to check the specs....the inlet pressure doesnt seem to be an issue the regulator is set up with a 200# inlet pressure gauge and my compressor maxs out at 175. i probaly would dial the output of the compressor  into the regulator down to the 90 psi range i have painted alot with this compressor and i know it will produce the scfm the hvlp guns require. The  scfm on HVLP guns is pretty high but if the conversion is scfh /60minutes to equal scfm.  then 1500 scfh/60 = 25scfm.....and it looks like from a quick google search 15-25 scfm is pretty std for the HVLP guns.  so then it may work?   i may have to try this just for giggles and grins.  now what do i need to paint?edit....well heres the specs for the new models.....i think it will work assuming the old specs for the 92-50 and new specs for the 9200-50 are in the same range, its saying at 125 PSI it will flow 2500 scfh or 41.66 scfmhttp://www.harrisproductsgroup.com/e...odel-9200.aspxLast edited by 37ford4dr; 10-03-2012 at 11:42 PM.bobs77vet/37ford4drEastwood digital TIG200HH190Lincoln Invertec 155sLincoln weldpak 100sears/craftsman (lincoln) 50a 240v buzz boxO/A rig Harris gaugesnexion cut 50 dxchicago electric (HF) 240v spot welder
