Price update, $250 OBO.
Quincy model 325 air compressor, tank & accessories for sale, great starter kit for a high quality central air compressor setup, $250 obo, located in Charlottesville, VA
Compressor: Quincy 325, serial number 214555L, i believe it's a mid 1950's vintage. I don't know much about it but I believe it's rated for 8 to 18 (ish) cfm w/ a max operating pressure of 175 PSI. This is based on some very quick internet research, not verified.
Motor: Leroy Somer, 5hp, 208/240v (split phase)
Tank: Bard, 1955, i believe it's 58 gallons. No visual issues but I haven't pressurized it or tested it
Accessories: (2) 50' 1/2" rubber hoses, (1) 50' 3/8" hose w/ retractable reel, (2) air filters (one w/ a built-in regulator). All harbor freight (central pneumatic) and new in box. Additionally I've got some random fittings, a pressure switch, and a pressure gauge. The pressure gauge is oil-filled and some of the oil leaked out in storage (the back rubber came loose, its back on now), I imagine it's an easy top-off.
Story: I bought this from a wood shop that was upgrading about 5 years ago. At the time I was looking for a high-quality, high CFM, low noise, central air compressor setup for my shop. I was able to confirm it operates when I bought it (very satisfying, low, quiet, chugga chugga chugga, as you would expect), but haven't hooked it up at my shop since it's not wired for 240v. To be complete, it would need to be mounted, tubing to the tank, and the associated pressure switch & accessories to control it. Ultimately I ended up going the battery powered tool route and never really needed such a robust air compressor, so it's sat in the corner of my shop for years. Now I'm going through a bit of spring cleaning and would love to pass this on to someone that can use it.
It's very heavy (200-300 lbs?) and large, I had to use an engine hoist to move it around.
