i'm thinking of painting my truck in parts. ie remove the fenders and paint them one at a time. same for the door, hood ect.
i'm thinking that this technique will require less from the compressor. by that i mean by the time i drain the tank i will be done painting the part.
am i making an incorrest ssumption?
would a lvlp gun be better suited to my situation? | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | am i making an incorrest ssumption? For the most part, yes. Get a compressor that has an output rating (CFM, not just PSI) that is above the requirements of your air tool or you're asking for trouble.

Before I had the money to buy a good compressor AND a good moisture-removal system (in 2003), I bought a turbine-based HVLP system (2-stage, Accuspray - now owned/sold by 3M Spray Equipment). This requires no compressor and no air-filter/air-dryer. This is a fine system and comes with an excellent non-bleed, pressure-feed gun.
All my air tools worked fine with a 30-gal 5-hp portable compressor.
In summer 2008, I upgraded to a larger compressor for use with a large media-blasting cabinet (and a larger pressure blaster unit).

what limmitations did you run into with the turbine unit?
my goal with the paint job is not perfection so i will look into one of those units. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
No limitations. All the advantages of HVLP with none of the liabilities of using a compressor (especially in a high-humidity location). It worked well with high-quality and lower-quality PPG auto paint.
One factor that has to be kept in mind is that the turbine air is warmer than compressor air - a good auto-paint vendor should be able to recommend the right reducer.
