I use the Harbor Freight 2.5hp 21 gallon unit. I also have a pressure pot. I blast at 90psi and get about a minute of blast time before the compressor kicks on. It usually takes me about 45 minutes to blast one of my pipes. If I was to go a bit craggier with the blast I turn the PSI up and it takes about the same amount of time.

I can finally say I am in the market for a bigger compressor!! Just trying to decide exactly what I want and then Heath and I will spend a weekend putting in a 220 subpanel to the garage (which is what we should have done 2 years ago when I got my new lathe).

I use a 100l (not sure how many gallons that would be).
Of course bigger would be better, but it gets the job done.
45 minutes per pipe, in exchange for less $$$'s is not too bad for now. In my book, in any case.

I don't know what your budget is for a bigger unit but I highly recommend Kaeser rotary screw compressors. I've had an SX-6 (5 HP) on a 60 gallon tank and a Kaeser refrigerated dryer for a number of years and have had no issues. Big plus: about half the noise of a comparable size piston unit. 220V on the compressor and 110V on the dryer.

What's the price tag on your setup? Heath has been looking at rotary screw compressors.
