   Terry,

        I have a smaller P-C compressor and like it very much. I would like to point out

   that 25 SCFM is 150% greater than 10 SCFM.

   So much for my Sunday math. Do you use it for air sanders? How much smaller?

   Terry,

        Mine is a 3 1/2 hp, 20 gal hot dog. Definitely not for sanders. For commercial work

   a commercial compressor is the ticket.Mark in WBGV

   I have a buddy that has the PC compressor you're considering and he loves his, he uses it for painting cars. Great price on a excellent compressor...

   Terry, any oil less or oiled compressor under 15 scfm is basicly a consumer machine. Any sander, drill, driver/ratchet  -even a petite die grinder-  is a windmill type turbine that eats cfm's big time and are usually understated.
   If you need a compressor to earn a living get a real one , a two stage ingersol is one choice (they also make consumer units made in Italy ) . You should also find out the difference in cfm and scfm as it is like hp and developed hp as used in some specs. Paddy

   DEFINITELY go with the two-stage with at least a 60 gallon tank. Pneumatic sanders gulp an INCREDIBLE amount of air! Have you looked at compressors by Eaton Manufacturing? http://www.eatoncompressor.com

   I tried to run a random orbit sander with my 5 HP, 60 gallon single stage Campbell-Hausfeld...not a pretty sight!

   I agree that the larger compressor is the way to go, but the Dynabrade sanders do not consume as much air as they used to. You can successfully operate one of these sanders from one of the moderate sized compressors (like you see at Home Depot, etc.) and the compressor will keep up, but it will have a high duty cycle. I have a Curtis Toledo 2-stage, and I have run two Dynabrades at the same time.

   Never heard of Eaton, but their price for an 80-gal two-stage is about the same, and they throw in some useful features at no extra cost. You can even pick the paint color <g>:

   PREWIRED MAGNETIC STARTER --wired in conduit ($150.00 value)

   CONTINUOUS RUN ($150.00 value)

   RAISED MOUNTING PLATFORM under compressor pump ($40.00 value)

   AUTOMATIC BELT TIGHTENER ($35.00 value)

   3/4" BALL VALVE AIR OUTLET ($15.00 value)

   LOOK! AUTOMATIC DRAIN--all brass, very heavy ($115.00 value including installation)

   BALL VALVE CRANKCASE OIL DRAIN to drain oil out of compressor ($14.00 value)

   At some point, maybe it's simpler just to buy a heavy-duty electric sander like the Festool Rotex (~$500), put the vac on it, pay for their expensive PS discs, and call it a day. Doing the math to figure out how many cheaper Dynabrade-sixed, 5" discs it would take to break even on the thousand-dollar difference would hurt my head...........

   I have an 80 gallon, 5 hp Ingersoll Rand in my shop.  I believe it to be an outstanding air compressor.  More than enough cfm to run any tool, including da sanders, inline sanders, and even large impact wrenches for large (dump) truck tires.

   I had a PC compressor, and returned it after 2 days.  It malfunctioned several times.  I just didn't need the headaches.
