Quincy Air Compressor 132 Gallon Rotary Screw with Dryer

Quincy 4152022000 QGS-20S Rotary Screw Air Compressor Value Package with Dryer

This is a Value Package, and that word is doing real work. Quincy builds the QGS-20S airend, the 132 gallon horizontal receiver and the refrigerated air dryer as one factory assembly rather than three items you buy separately and connect on site. The interconnecting pipework, the mounting and the control wiring are already done and already matched.

Anyone who has commissioned a compressor room from parts knows why that matters. The dryer bought separately arrives with its own footprint, its own inlet and outlet sizes and its own opinion about where the receiver should sit; the pipework between them becomes a small fabrication job, and the first place moisture appears is invariably a joint somebody made on a Friday. A packaged unit removes that whole category of problem, and it removes the argument about whose fault a fault is.

The numbers this unit will actually stand behind

One of the more useful things about this particular part number is that its data is unusually complete. It publishes a free-air delivery of 60.9 CFM and a sound level of 71 dBA — two figures that several of its siblings in this range record without any unit attached, which makes them unusable. Here you can size your tools and site the machine from real numbers.

60.9 CFM is a serious continuous supply. It comfortably runs a busy multi-bay shop's impact wrenches, ratchets and blow guns simultaneously, and it will hold up a media blaster or a production spray gun of the kind that flattens a reciprocating compressor inside ten minutes. 71 dBA is the more surprising figure: that is quiet enough to stand beside and speak normally, which is why a full sound enclosure is worth paying for when the compressor lives in the working area rather than a plant room.

One honest caveat on the output. The marketing copy that has run on this page states 60.9 CFM, and that is the figure we have carried forward. The product's own specification metafield records a very slightly different value for the same rating. The gap is fractional and it will not change which tools you can run, but if you are sizing to the last unit of air — a fixed-consumption machine, a spec-driven install — contact us and we will confirm the exact rating from the current Quincy datasheet rather than have you design around ours.

Continuous duty, and the dryer that goes with it

The duty cycle is 100%: this compressor is built to be loaded and running, and the oil-injected twin screw element is sealed and cooled by the fluid that lubricates it. A machine that runs continuously also produces water continuously, which is precisely why the packaged dryer is not a luxury on a unit like this. Air leaves the airend hot and fully saturated; the aftercooler drops the temperature and takes out the bulk of it, and the integrated refrigerated dryer takes it down to a dewpoint low enough that the remaining moisture stays as vapour all the way to the tool.

The difference shows up in things you would not initially blame on the compressor: rust blooms inside a header, air tools losing their edge months early, moisture spots in a finish coat. On this package, both stages of that treatment are present and every source in the product's data agrees they are — the title, the feature list and the specification table all record the dryer as fitted. That is not true of every model in this family, so it is worth stating plainly.

Will it fit, and can your building supply it?

The assembled package measures 74 inches long, 30.7 inches wide and 72.2 inches tall, and weighs 1,296 lbs. That is the heaviest configuration in this cabinet family, which is what a receiver and a dryer inside one frame costs you. Check overhead clearance and door height on the route in, and leave working space at the hinged doors and detachable panels rather than pushing it flat against a wall. The receiver outlet is 1 inch; size your distribution pipe from that, not from whatever fitting is nearest.

Electrical supply is the part to settle before ordering. This is a 208-230/460V 3-phase machine with a magnetic starter and Wye-Delta reduced-voltage starting. Quincy does not publish an amp draw or a recommended breaker size — both fields read "Consult Certified Electrician" — and we are not going to substitute a number of our own for a figure the manufacturer deliberately declined to print. Have a licensed electrician size the service, feeder and disconnect against the machine's nameplate before it ships. Electrical supply, siting and permits are the customer's responsibility.

Perfect for

Multi-bay automotive and truck service shops that need clean, dry air all day without a plant room. Body shops and finishing operations where moisture in the line is a quality problem, not just a nuisance. Fabrication and light production work with steady rather than peaky demand. Anyone who would rather buy one commissioned assembly than three components and a pipefitting job.

Specifications

What's included

From the manufacturer's feature list and specification table: the QGS-20S rotary screw compressor with gear-driven airend, the Infologic2 Basic Controller and its display panel, a TEFC electric motor with IP 55 wash-down protection, the integrated refrigerant air dryer, the 132 gallon horizontal receiver, aftercooler, air filter, pressure gauge, oil sight glass, magnetic starter, low-oil shutdown and a spin-on fluid filter. An electronic drain valve is not part of the package, so tank draining is a manual routine unless you add one.

Shipping and delivery

Freight only, within the lower 48 states, free of charge. At well over half a ton in a tall crate, this is not a shipment a driver can hand down. Have a loading dock, a forklift with the capacity to take it off the trailer, or arrange to collect it from the carrier's terminal. Delivery to a residential address carries a residential fee. Inspect the crate on arrival, and note any damage on the bill of lading before you sign — once it is signed clean, the carrier's position is that it arrived intact.

Warranty

Standard recorded cover is 1 Year consumer and 1 Year commercial. An extended 3 Year factory warranty is available, and the True Blue 5-Year warranty applies when a Quincy authorized start-up commissions the machine. That start-up is a precondition of the longer cover rather than an optional service call, so schedule it with the installation. If a fault appears, stop the compressor and speak to us before anything is opened up: a unit that has already been taken apart is a much harder claim to support, and on a package this size that is a lot of coverage to risk.
