  • FREE air compressor does not build more than 30 PSI of pressure??

    No wonder it was free...... I picked up a free HUSKY 20 gallon air compressor. that only builds 30 PSI of pressure. I checked piston ring and everything looks good. Tank pressure and regulator pressure will not go above 30 PSI. Any suggestions on what I should check.?? Here is the compressor type....

    I picked up a similar style compressor in similar shape a few years ago. A friend of mine had the bright idea to sand their wood floor with an air sander powered by a 12 gal oil less unit. They said it only got hot once.....but that's all it takes! Anyway, on that one the piston ring melted out of it's slot but I also found that the little reed valves inside the head had basically crystallized and were worthless. What I did on that one was find a local shop that dealt with the warranty work on the machine. It was a CH, so you might be able to take the same route since I think most of HD Husky line is just a CH with a red paint job. Anyway, when I talked to the shop owner, he said that most of their warranty work on those small machines was for burned out motor. well, they just replace the whole motor/pump assembly when that happens. He gave me (or sold really cheap...can't remember) an assembly that had a bad motor. From there I went back to the shop and stripped both down and put the good pump head on my good motor and threw the other junk away. It's still running today....only not sanding floors

    Maybe that will help

      Sounds like you got a free pressure tank with wheels.

          Fixed

          Bad gasket on line coming out of manifold. 10 cent oil ring and runs like a champ.... Holds 150 psi now and does not leak down. Pretty good for FREE....!!!!

                  compressor question

                  my compressor takes forever to build up pressure to 115- then just a few cuts later it's running again. what should i look for to fix the problem? it's a home depot husky. have had it for maybe 5 years - never have liked it but... thx, cat

                    Depends what CFM the tool is you're using, size of tank, and CFM of compressor.
