Compressor Help

[bsmith405]

I've been lurking here for a long time, mostly researching compressors, and finally decided to join. I've been planning on purchasing a new Quincy QP compressor in the next month or two, but wanted to look for a rebuild project first. This compressor caught my eye and I was thinking about taking a look at it tomorrow. Anyone know what model this is or what pump that is. What should I look for during inspection if I am unable to power it up. What would be a good offer to make? I plan to use this on my Econoline blast cabinet and my Powermax 45 plasma cutter. Any help with my questions as well as where to start with a rebuild would be greatly appreciated. Thanks!

Doesn't look big enough for a blast cabinet. Check the specs.

It looks like an earlier model Quincy 216 to me, neat pump and well-built. There's two clues that give it away -- first, you don't see an intercooler wrapped around the crankshaft between the flywheel and the crank case, which means it's a single stage. Secondly, there are at least two suction and two discharge valves in the head. The fact that it's got a 5 HP motor on it (if true) probably means it's a 216 being driven at around 900 RPM. If you know the diameter of the motor pulley, we can probably give a pretty decent guestimation of the output.

At 5HP, a 216 would deliver around 10 SCFM @ 100 PSI, which will drive a smaller, less industrial blast cabinet, but it will probably be running continuously (which, by the way, this one is designed to do). The original rings on these weren't good for much past 100 PSI, but if you upgrade to the newer piston rings, it may be able to push 125. I'd watch the current being pulled by the motor, though, as at its current RPM, this may burn out the motor and/or begin to tax the electrical side of things.

I would probably pass at that price and keep my eyes open for a 325 or even a 240 if you don't need the higher pressures generated by a 2-stage pump. Late model 240s are known to easily push 135 PSI at higher flow rates even on a 5HP motor.

Edit: If this one actually delivers the rated SCFM currently as-is, a rebuild kit is probably ~$100. Simply cleaning up the valves and pressure lubrication system may keep this thing running another 10k hours with only basic maintenance, which is more than can be said for big box store compressors at the same price. Maybe the seller will negotiate?

DO NOT BUY A QUINCY COMPRESSOR!!!! They do not honor their warranty. Furthermore, do not buy from Northern Tool, they will give you the run around. My Baldor motor died after the first year, Northern Tool warranty is 24/24 but Quincy says 1 year unless you keep buying oil, every year! ( I bought the 5 year for the pump !) True blue my ***, American way is to screw the little guy, buy china, at least it will last.

You may be the first person to ever tell someone NOT to buy a Quincy. Every person I know that owns or uses a Quincy loves them and has had little or no trouble with them. Just sayin'.

I agree, I operate 3 large industrial Quincy screw compressors and have never had anything but good experiences with the company as well as their local distributor. Always been quick about repairs and do anything that is needed when there are problems with them.

@^^^LoL, that's the first. Most guys around here that praise Quincy only mess with older quincy types with oil pressure lubricated and two stages. If I were to invest in a good compressor and choose b/t Quincy and Champion, I choose Champion in every aspects.

And I own and run a Quincy 210.

Worked on compressors all my life, 50 years, and the best compressor under 10 HP is a Quincy. I'm talking about the QR25 series pressure lubricated. Not the Chinese import one. That one may be alright for the homeowner but not for industrial use.
Sorry for your experience Braden. The 5year warranty is for the compressor pump and not for the entire outfit. The electric motor manufacturer will enforce the warranty on the motor.
