![]() ![]() One of the first things I noted was the relatively slow charge time of the 30 gallon compressor tank. When higher air pressure is required, a two stage compressor must be used. 100 psi, (pounds per square inch) is the limit and rating of Quincy’s entire line of single stage compressors. Knowing that a model 240 compressor can produce 23.5 cfm (cubic feet per minute) of air flow at 100psi at its maximum speed of 900rpm, I made an educated guess that my 230 compressor was able to produce right around 20 cfm of air volume at 100psi. Luckily the current QR-25 brochure listed the cfm output of the 240 compressor as well as a suggested motor size and rpm range. My model 230 compressor has a 3-1/2″ bore and 3″ stroke, whereas the slightly larger and current model 240 has a 4″ bore and a 3″ stroke. It turns out that the only major difference between the 230 and the 240 compressors is the bore of the pistons. After perusing Quincy’s current QR-25 lineup I noticed that the model 240 compressor was strikingly similar in design and appearance to my model 230 compressor. The compressor model number “230” happens to be a common number for electrical voltage “230 Volts” so all of my searches ended up with hundreds of different 230 volt compressors. P1070132, P1070138, P1070185, P1070195, P1070191īecause Quincy no longer manufactures this specific model compressor today, it was rather difficult to find information and specifications on it. The workbench in my garage is narrow, so I needed to reorganize the components so that they would fit without obstruction. His compressor outfit rolled right underneath his workbench, exactly how I planned to store and use my compressor. Arthur, like myself lives in suburbia and understands how valuable space is. I have never seen a model 230 compressor factory installed on a smaller tank. At this time I can only speculate that this compressor was mounted on a 60 or 80 gallon tank. For this compressor to outlive a three phase motor is a testament to how overbuilt these Quincy compressors are. When the 5 horsepower three phase motor that drove it burned out, the school discarded the compressor and he took the compressor head home. Arthur told me that this compressor powered the blast furnace of Merrick High School. Everything sounded normal despite the plumbing and wiring being an absolute mess. ![]() Arthur, the previous owner was able to power it up for me so that I could hear it work. It came with a small 30 gallon air tank and a 3 horsepower 230 volt single phase Dyna motor. The compressor was located about twenty miles away in Baldwin, New York. I was surprised to win the bid at just $180.00. A friend of mine in Virginia led me onto this compressor as it was nearby and inexpensive. In April of 2015 I was in the market for a moderate sized industrial compressor to run my air tools, blow guns and my newly acquired Trinco blast cabinet. ![]()
