This is what I have...got it last year...right at $1400.

The compressor it replaced was also a Quincy...5hp two cylinder single stage that ran well for me for over 25 years and was used when I got it, but it was on a very old (1933) 60 gallon tank that I was getting worried about, so I treated myself to a new unit.

Quincy compressors are or were well regarded as excellent quality for many many years.
The QR series I believe is what earned that reputation. They are heavy, run slower than other brands might, so quieter and last longer because, and they have internal oil pumps and often external spin on filters. Industrial quality all around. They usually have unloaders too that work on oil pressure and before oil pressure builds at startup or if pressure is lost they unload and freewheel for easier starting, longer life, and to reduce damage if run out of oil or other oil system failure.

The QT series are a somewhat newer offering as their more affordable line with fewer of those good design features. They may not all be US made compressors?

The recent QR series are similar to the good ones of old but have fewer cooling fins on the cylinders and rumours of not being quite as good as the old ones.

I have about 6 Quincy compressors, two of the cheaper QT series, 3 older and one newer QR series with the oil pumps. All good compressors.

You didn't mention. So I'll just throw it in;
If your tank isn't emptied, that is, if you don't empty the water accumulation in the tank. It will limit the tanks (air) capacity, which also effects the run time for the pump -- seems to run constantly.
But in the end, even if you do find that there is a lot of water in the tank. It looks that if your wallet will support it, it's probably in your best interest to simply get a good (better) replacement pump for your tank. smile

Harbor Freight often has decent pumps on sale for a good price, and most of them offer a lifetime warranty -- and made in the US of A. smile

I decided to replace the switch and sell this hobbyist level one and upgrade. By the time i upgrade to a better motor, pump, switch, wiring and plumbing - I might as well buy a new one with a new tank. This tank seems fine but its old.
