Quincy 4153DS12HCA23 QT Pro 15 HP Two-Stage Air Compressor, 230V What separates this compressor from a cheaper machine of the same capacity is what comes out of it. The QT Pro pump is specified to keep oil carry-over below 5 PPM, and it works across a 145 to 175 PSI band rather than at a single headline figure. Those two facts together describe a machine intended to feed a pipework system and finish work, not just to fill a tank. It is a 15 HP, 230V 3-phase unit on a 120-gallon horizontal receiver, driven by an industrial-duty Baldor motor through a cast-iron four-cylinder pump delivering 51 CFM at 175 PSI. Oil carry-over is the specification nobody reads Every oil-lubricated compressor passes a little oil into the air stream; the question is how much. Below 5 PPM is a low figure, and the reason to care is that oil downstream is expensive in ways that do not look like compressor problems. It contaminates paint and adhesive work, which shows up as a redo rather than as a breakdown. It swells and degrades the elastomer seals inside air tools and pneumatic valves, which shows up as tools that need rebuilding early. And it films the inside of your pipework permanently, so a future upgrade inherits the contamination whether or not the new machine is clean. Fixing that at the pump costs nothing extra at the point of purchase. Fixing it afterwards means coalescing filters, their pressure drop and their consumables, forever. A working range, not a single number Air systems are designed around the pressure at the tool, not the pressure at the compressor. A machine specified with a 145 to 175 PSI working range tells you where it cuts in and where it cuts out, which is what lets you size a receiver and set a regulator sensibly. Running at the top of that band and regulating down at the point of use gives you stored energy for the moments when several tools open at once, without asking the pump to chase demand. Discharge is through a 1-inch ball valve outlet — a full-bore port that will not throttle the machine before your piping does, and a genuine convenience when the system has to be isolated for a repair. The mechanical package The motor is an industrial-duty Baldor unit that Quincy specifies for cooler running, which is a durability argument rather than a performance one: winding insulation life is governed almost entirely by operating temperature. It drives a cast-iron four-cylinder two-stage pump — four cylinders because splitting the work across more, smaller bores lets the pump make its air at lower stress and lower speed. The pump is rated at more than 50,000 hours. A factory-installed industrial-duty magnetic starter provides thermal overload protection on the motor, which a bare pressure switch cannot do and which matters on three-phase power where a lost leg destroys windings without warning. Will It Fit? The unit is a horizontal 120-gallon receiver measuring 78 inches long, 28 inches wide and 55 inches high, weighing 995 lbs. Leave working room rather than the exact footprint: belt guard, oil sight glass and the tank drain all need to be reachable in place, and the cooling fan wants room air rather than its own exhaust coming back at it. Power is 230V 3-phase. Verify the voltage at your own panel instead of inferring it from a neighbouring machine, because the other common shop three-phase supply is a different voltage and mismatching them shows up as hard starting under load and a motor that runs hot. The magnetic starter is fitted. Breaker and conductor sizing belongs to a certified electrician working from your service and your run length, and that is exactly what Quincy documentation says rather than publishing a figure. Confirming the supply, the doorway, the access route and the floor before you place the order is the buyer responsibility. Perfect For Body shops and refinishers, where oil carry-over at the source is the difference between a clean panel and a redo. Hard-piped multi-bay workshops on 230V three-phase running a ring main from one receiver. Machine and fabrication shops feeding air tools and pneumatic machinery that are intolerant of contaminated air. Anyone replacing a compressor that oiled its own pipework and does not want to repeat the experience. What Arrives The compressor is supplied assembled: the cast-iron four-cylinder pump and the Baldor motor mounted on the horizontal receiver, with the industrial-duty magnetic starter fitted at the factory and the 1-inch ball valve outlet in place. Compressor oil, hose, filtration, dryers, regulators and downstream isolation valves are not listed as included in the documentation we hold, so treat them as separate purchases — and tell us in advance if any of them controls your commissioning date, because they are easier to ship alongside the machine than after it.

The product title, the page copy and the manufacturer specification table all describe a 120-gallon tank. One line of the spec data we hold records a smaller receiver. Three sources against one is not the same as certainty, so if tank volume is part of your sizing calculation, ask us and we will confirm it with Quincy in writing before your order is placed. The model number. The heading and the specification give this compressor as 4153DS12HCA23; the web address for this page uses a different prefix on the same code. The heading and the specification agree with each other and with the numbering of the rest of this Quincy range, but if you are matching a part number for a fleet standard, confirm it with us rather than reading it off the address bar. Certification, Stated Plainly The data for this compressor records ASME, UL and CSA marks. The ASME mark is the significant one and it is narrower than people assume: it is a pressure vessel certification covering the receiver, its design, its material and its construction. That is what an insurer or a workplace inspector will ask about on a tank of this size, and it is the reason an unmarked receiver is never a bargain. The electrical marks cover the motor and controls. None of them certifies air quality, none of them discharges a local permitting requirement, and none of them replaces the periodic inspection some jurisdictions require of pressure vessels. Check the local position before installation. Shipping and Delivery Delivery is by freight carrier within the lower 48 states, free of charge. Before you order, settle two things. The first is unloading: nothing about this crate can be lifted by hand, so you need a forklift or a loading dock at the destination, or you can choose to pick the shipment up from the freight terminal yourself. The second is the address type — a residential delivery is a different job for a carrier and carries a residential fee, so declare the destination accurately. When the truck arrives, look the shipment over before signing anything. Bent guards, a damaged gauge, oil where there should not be oil, or a corner of the receiver that has clearly met a forklift are all worth noting on the bill of lading at that moment. Damage recorded on the paperwork is straightforward to claim; damage discovered after a clean signature usually is not. Warranty Quincy covers this compressor with a 1-year factory warranty, which extends to the 3-year No Bull warranty when the machine is registered with Quincy and maintained using Quincy kits. Register it as part of commissioning; the extension is conditional and cannot be applied retrospectively once something has failed. One more piece of standing advice, which applies to every compressor we sell: if a fault develops, speak to us before the pump or the starter is dismantled. Partly disassembled machines are the most frequent cause of a declined warranty claim, and it is the easiest one to avoid.
