For those of you that have big compressors, (and those that don't, too!) tell me about your air compressor use..

What do you do that I can't with my 5 CFS 8 gallon? Here's your chance to tell me why I should've bought a bigger compressor. :)

My friend bought a 30 shortly after I got mine, which is the 8 like you have. The "biggest" benefit that I saw was that his doesn't have to run very often to fill up when you're using it for extended periods of time. Other than that, not a whole lot that I can think of. It's easier to take mine with me when I go somewhere than it is for him.

Well, My 80 gal. i got free out of a guys garage that burnt down,of couse i had to replace the 3 cyl. compressor and motor but the tank was still good.I love the thing,i can run it forever and it wont run out unless i shut off the motor for a while.I also have a smaller portable one like yours so im not being biased but i just dont like it very much because it runs out so fast.

Well I gues the pro's are being able to run a impact for like a couple of minutes without the motor kicking in and the cons are price and size. BTW I have a 60 gallon dual stage

6 to 8 h.p with 60 to 80 gallon tank work great when you are sand blasting.

I have a 60 gallon...it's awesome for grinding, etc....you don't have to stop and wait for it to catch up like I had to do with my 30. It's better for spraying paint too, when you need large quantities of air (my dad's a bodyman so we had to take that into consideration when we bought the compressor). Plus it just runs less....the noise of the engine can get annoying after a long day in the garage (I CAN'T HEAR MY RADIO!!!).

80 gallon Ironman brand from the late 70s?
used heavily with geared orbital sander, die grinder, air drill, filling 5 35" tires after sand dune trip

mainly depends on what you use air for, if you run large sanders, air drills, bodysaws, they require lots of volume to continue working
if you dont do any bodywork, well no worries for you
a 1 gallon compressor can run air wrenches and 3/8" impacts for 10 seconds or so
a 6 gallon is fine for painting cars as long as it has an oil compressor
those oil free things are the noisy cheap junk you can find anywhere for little cash
