  • Compressor recomendations ???

    I need a small compressor for die grinding, deburring, part cleaning, etc.
    Most likely something in the 5 - 8 gallon, portable range.
    What brands do you recommend?
    I've read some AWFUL reviews about Craftsman. YIKES !!!
    Home Depot? Lowes? Harbor Fright?
    Or should I go with High-Dollar-Willy?
    Help me out fellas....

    Figure out how many cfm you need to run your tools and how much pressure you need, then buy a compressor that delivers that cfm at that pressure with a tank size of your preference.

      Well, the average die grinder needs about 4-6 CFM's and 90 PSI, which really ain't much.
      But which Brands are good?
      I was thinking Craftsman, UNTIL I read the reviews.

        I have a small Rigid I like; semi-portable.

        If I had the space, I'd have a nice big two stage... but for now, this will do.

          #1 NOT OILLESS Noisy, you will go deaf, and broke replacing PLASTIC pistons...
          #2 Belt drive, so if pump dies easily replaced...
          #3 1740 rpm 110 and 220 motor, if not affordable.... get 3450 rpm... Running big pumps slower makes them last...
          #4 Cast iron pump...if not affordable at least castiron liners...
          #5 1 to 1.5 real hp is enough for most light work
          #6 CFM ratings are also inflated by dropping pressure.. What you need is at least 6 CFM at 90 PSI...

          My cast iron pump, belt drive motor Cambell Housefield, has been working hard for 23 years in semi commercial use... sometimes 5 or 6 hours continuous running a day.

          If you can run 220 to it, it will cause less blinking of shop lights on start.....

          ALL Electric Compressor Motor HP ratings are bogus, a 110 v ~1.5hp motor draws 15 amps (max for normal 110 circut)

          Notice HP on motor says SPC or Special.. Right next to Amp and volts so you can see what you actually are getting

            this man speaks the truth. especially the stuff in bold.

            i doubt you're going to find a really "portable" model with a cast iron head, but i'd take cast iron over aluminum any day after having a craftsman oil-free compressor that has caused a lot of problems.

            anything pneumatic or pneumatics-related that craftsman makes has been an utter disappointment to me. it's odd seeing that they have some of the best hand tools out there and everybody i know who has a craftsman toolbox with ball bearing slides loves it...

              I have a bus air brakes compressor turned by a scrapped 3 phase saw motor modded to single phase, fastened to a old gas bottle for a tank.
              Cheap compressor, cost 20 quid for the compressor head from the local bus depot, the rest scrounged free.
              If you've lots of cash though you could go and buy a nice broom wade or ingersol.
              Build it, bodge it, but dont buy it.

                I have two compressors!

                The first is the static one that I've been using for hobby use for nearly 20 years, it's a 3hp 100litre twin piston FIAC. It started popping it's 16 amp breaker a while back and needed a new starter cap, but other than that it's been rock solid.

                My second compressor is a little portable 2.5hp unit that can be run on a standard UK fused 13 Amp plug unlike the big one. It came with blasting gun, blow gun, tyre inflator, paint gun, parafin gun, a long and short hoses and couplings all for the sum of £82 (three years guarantee).

                It's from the discount ALDI chain, they do airtools once a years. I've been quite impressed with ALDI tools, cheap but usually quite adequate for hobby use.

                  if you'd consider scabbing one together from parts, i'd highly suggest looking into york air conditioner compressors. there's probably at least a hundred websites detailing their conversion to air compressor on all of the 4x4 sites out there these days.

                  many auto manufacturers used york pumps in their vehicles. ford and volvo are two i know of for sure and they pumped out tens of thousands of cars which are rotting away in junkyards today...

                    if waht you are loking for is a small 8 gallon unit go for the ch 8 gallon one i have one and i use it for all my auto motive and small engine stuff i use die grinders on it, as well as painting and so on its a work horse and i uses oil so its quiet when compared to and oil less one, very realible and you can usualy get just hte compressor it self for under 200 bucks or get he kit i did at home depo it was 229 canadian at the time i thnk it still is to if i remeber right, any how its a awesome machine and wil suit the needs you listed, i have also done sand blasting wiht it to , its not to bad but could be better in that department, other wise its a great machine and well worth every penny spent, one thign i did notive is the aftermarket tools like somna for example use less cfm then the same tool in a ch or master craft and so on, and the price was less and quaility is good as well.. i even bought pitbull air ratchet ok so i was really cheap but you know it performs just the same as the ch one and less cfm required.

                    anyhow thats my take on this one

                      you need 14 cfm for die grinder if you are using it continually (thats more than 5 Min's at a time)

                      i know this ..because that is what my compressor is ..and it just about keeps up with them ..

                      before anyone says ..it cant be a 14cfm comp..it is ..and its an Ingersoll rand one and genuine 5hp

                      what ever the manufacturers state as the cfm for those grinders ..it can be wrong.........

                      all the best.markj

                        Also don't think a bigger tank will help, CFM is what you need. The tank is probably the most mis-understood part of the compressor but it's the part people see the most, bigger is better right? Not necessarily and a tank too big for the compressor is as bad or worse than one that is too small.

                          Having had several compressors, I'd say a cast iron with separate motor and at least a 25 gallon tank and 1.5HP is the minimum for any kind of shop. These are usually 6.5 @ 90 / 8.5 @ 40 or thereabouts. Good enough for most stuff. If you have a corner, a vertical 3.5HP 60 gallon unit only runs about $100 more than a good portable and is 5+ times better. If you were close, I have an excellent used 25 gallon Porter-Cable compressor I'd make a deal on.

                          Actually, I see you're down around San Antonio, which isn't super far in Texas distance terms.

                            A_E has it right: if you're going to run any air tool that has a motor (grinders), you need a 5Hp compressor. I've had an old Gardner-Denver 2-cylinder single stage outfit for about 30 years now, and running either a die grinder or angle grinder steadily will keep that compressor running.

                            A bigger tank will help only if your compressor is a bit marginal and your tool usage is intermittant.

                            If the compressor you're considering runs on 120 volts, it's not big enough, period.

                              Well I bought a 5 HP Horizontal Model. I was told (yeah Ill believe anything) that it was a Devilbiss Two Stage. Then i did some work for a airvcompressor company in town. The gentleman comes into my home shop looks at my compressor and says..,,,How do you like youre SWAN AIR COMPRESSOR FROM CHINA. I was shocked i thought it was american.(I dony like chinese stuff in my shop) anyhow it is solid a two stage and has been totally trouble free for a LONGb Time. So if you see a swan cast iron 5 horsepower air compressor fear not it works damn well.
