hpfiend Posted February 21, 2008 Report Share Posted February 21, 2008 Hey all, I have heard I need at least 80 gallons, with a 2 stage pump, 5 hp? Overkill? I don't plan on running any painters or anything- I just want to be able to run air tools properly for crank bolts, suspension stuff, and rear-end work. This would be in a residential garage- Could have 240 but only single phase. One mechanic at a time (me) or my dad. Quote Link to comment Share on other sites More sharing options...
Guest Hal Posted February 21, 2008 Report Share Posted February 21, 2008 I'm probably going to pick up a 33gal. It will cycle more often, but, it should be able to run fine for one person working on one car. Quote Link to comment Share on other sites More sharing options...
GRN96WS6 Posted February 22, 2008 Report Share Posted February 22, 2008 80 gallons is more than likely overkill for most do it yourself type jobs. I have a craftsman 33 gallon one and while it does cycle more often it seems to get the job done rather well. Quote Link to comment Share on other sites More sharing options...
Berto Posted February 22, 2008 Report Share Posted February 22, 2008 I havea 33 gal Husky with a 5.5 hp oilless engine. Works fine for what I need it. Quote Link to comment Share on other sites More sharing options...
FourString Posted February 22, 2008 Report Share Posted February 22, 2008 I have a single stage 60Gal 7HP (oiled) and I love it. I never need to wait on it. A buddy of mine just bought a portable Dewalt that has 200PSI working pressure. It's nice as hell. Quote Link to comment Share on other sites More sharing options...

schmuckingham Posted February 22, 2008 Report Share Posted February 22, 2008 What about if we were going to port and use a die grinder all the time? Quote Link to comment Share on other sites More sharing options...
verse Posted February 22, 2008 Report Share Posted February 22, 2008 I havea 33 gal Husky with a 5.5 hp oilless engine. Works fine for what I need it. Same exact one I have. Works great, it only cycles every 10 minutes if you are using it a good deal. Quote Link to comment Share on other sites More sharing options...
hpfiend Posted February 22, 2008 Author Report Share Posted February 22, 2008 hmm- well that will save me some money! will the 33 gallon 5.5 hp oilless single stage husky let me run 700 ft-lbs with my mac 1/2" impact gun? I don't know the CFM it requires right now but I can barely remove lug nuts with it right now- it probably maxes around 95 ft-lbs with our wimpy little compressor.

Clifford Automotive Posted February 22, 2008 Report Share Posted February 22, 2008 A 33 will do you fine. I wil be running twin 60 gals in my shop. I started with a 60gal and it did my fine. A 60 gal is overkill for residential. The 33 will take care of you for pretty much everything you need to throw at it. Quote Link to comment Share on other sites More sharing options...
Nitrousbird Posted February 23, 2008 Report Share Posted February 23, 2008 I have a Porter Cable 6HP/25 Gallon unit. It will eat up the tank with heavy die-grinder use. I'd suggest 35-40 w/ a decent motor for what you would want. If you can avoid oil-less at that size, do it, as the oil-less are a lot louder.

Dave1647545494 Posted February 23, 2008 Report Share Posted February 23, 2008 I would not buy an oil free compressor they are loud as fuck mine drives me crazy I would get the biggest compressor that fits comfortably in your garage a twin stage oil bath compressor will be much more quiet and the larger tank size you run the longer you can hold higher pressure on your air tool wich allows it to deliver more torque consistently. I have a little garage so I have the biggest compressor I can fit wich is an oil free 30 gallon it gets the job done but I have to wait on it sometimes if I'm running a die grinder or an air drill...... moral of this long ass post the bigger compressor you buy the happier you'll be Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted February 23, 2008 Report Share Posted February 23, 2008 Go one size bigger than what you think you'll need. Quote Link to comment Share on other sites More sharing options...
evil8 Posted February 23, 2008 Report Share Posted February 23, 2008 Die grinders ,dual action sanders, and air hammers will wear out a small compressor. In general, If you are working on cars the smaller compressor will work. Truck work requires a big dog. That Mac impact will eat up air on tough bolts, those 700 lb ft come at the cost of mass air volume. Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted February 23, 2008 Report Share Posted February 23, 2008 If you ever plan to do any sand blasting, got the bigest mofo you can fit in your space. Otherwise, something that has oil, you can probably pick up an older one on craiglist for cheap. Quote Link to comment Share on other sites More sharing options...
FourString Posted February 23, 2008 Report Share Posted February 23, 2008 Exactly. I media blast in my garage. My 60Gal keeps up just fine for what I need. Quote Link to comment Share on other sites More sharing options...
