oiless aircompressor question

[snapper]

Anybody got any expierence with these air compressors?? I have a nice big one but needed a smaller one for portable use. So i got me an older cambell hausfeld to use. It got a 3.5 horse motor (real number before they exagerated them) and a eleven gallon tank. Quite noisy but will be fine for away work.. Just wondering your expierence with them..

Snapper, air-compressors in general, and oil-less in particular, have been discussed at length in the past. This thread is just one of several you might want to read.

A considerable amount. Bottom line, in my opinion, is that they're relatively cheap and good enough for occasional homeowner use if you never run it more than 10 minutes at a time, but they're also very short lived if you use them regularly. I rebuilt the last one I had 3 times in less than 3 years, but the good part is that parts are relatively cheap and they're easy to rebuild in less than an hour.

i can see you all don't like them. oh well, for portable they are great. throw them in truck car what ever and go.. This isn't my primary compressor.. Now new question, The regulator doeasn't work. If you turn the knob out the air bleeds out the bleed hole continually.. tighten it down and it quits.. I took it apart and here is what i found. There is a needle like valve stickiing up from the base, looks to be spring loaded. Then in the top part which is what unscrewed, there is a plastic disk with an o-ring, then a spring then a metal disk which is pressed on as you screw in the handle. Any ideas how to fix this?? I tried oiling it and it still don't work. I can live with it not working, but it would be nice if it worked.. and also this isn't a seperate thing. It is made into a manifold thing with the switch and gauges and outlet.

Thanks guys.. snapper

Well . . ., that's partially true. /forums/images/graemlins/wink.gif /forums/images/graemlins/laugh.gif I used to have one that was a DeVilbiss 3/4 hp on a 2 gallon tank when we were full time RVers. It was light weight, small, fit in one of the motorhome storage compartments and was perfect for the use I had for it at the time; occasionally air up a tire or blow the dirt and/or dust off something. But when we bought the little farm, and I bought a bigger one (Craftsman made by DeVibiss) and started doing a little sandblasting, painting, and repairing/rebuilding air tools for mechanics, I had to rebuild the air-compressor every 6 to 8 months. /forums/images/graemlins/frown.gif

Your regulator problem and your description of it sounds quite normal, but with my own I was always able to thoroughly clean the parts with WD-40 and put them back together and they worked fine. If that didn't work with yours, I don't know what the solution would be. My personal experience with regulators has been that if they are not "re-adjusted" regularly, they do tend to stick and not work when do want to change the pressure setting until you take them apart and clean them.

just for my future reference, what is done in a rebuild, and bout how much do the kits cost?? I want to know so when this one goes south i can repair it..

Thanks..

Snapper, the first time my compressor broke, it was the reed valve that broke and parts would have been about $13, but it was still in warranty, so they gave me the parts. Then there were two separate "kits" available, depending on how many parts you needed. The more complete one (new cylinder, piston, and rod included) was about $40, if I remember right, and the other one (piston ring, o-rings, and cylinder) about half that. By the way, you know that nice plastic housing around the motor and compressor serves two purposes; (1) they know you probably wouldn't buy it if you saw what you're buying /forums/images/graemlins/wink.gif, and (2) it keeps it from throwing parts at you when it blows up. /forums/images/graemlins/wink.gif /forums/images/graemlins/laugh.gif And I'm only half kidding. Besides the three times of fixing the compressor itself, the cooling fan (squirrel cage) broke loose once; very noisy and it hit the inside of that housing hard enough to crack it. /forums/images/graemlins/frown.gif

Of course, keep in mind that I was running it for long periods of time. In fact, when the reed valve broke, I was sandblasting and it was running continuously for about 30 minutes. And after you take one apart once, and get a good look at it, you can very easily completely rebuild it in well under an hour, even while sipping your coffee or a beer. In fact, I think I could very easily do it in 30 minutes or less.

sounds cheap enough for me.. Mine never runs more than two or three minutes at a time. mostly use it for impacts and ratchets. It takes under three minutes to fill the tank empty and about 40 or so seconds to catch up if not ran down far. so it ought to last me a while.

Thanks bird and whomever else.. Snapper

Snapper -- I have a small (4 gallon) PorterCable oilless compressor I use for filling tires and operating small woodworking air tools like staplers, finish nailers, etc. I like the portability and the low cost, and also the speed with which it comes up to operating pressure. The portability comes in very handy, i.e., I used this compressor to reshingle a rental property.

For big jobs I have a 240V 60 gallon oil lube compressor. Pumps out an incredible volume, but is not portable. I think each has its place. I'd hate to fire up the big compressor to fill a tire, but I don't dare run the little one for big jobs.

I too have the Craftsman (Devillebiss) oiless compressor. Its lable says 4hp but I doubt that since it runs on 110v. I havnen't had to rebuild it yet after 8yrs and I use it quite bit, and it will run continously for 15-20min when I run tools like a die grinder. I wish I would have paid the extra 50-75 bucks for the oil type, they're much quiteter. I hate how loud it it is.
