Quincy Air Compressor 5153DS12HCA23 QP Pro 15 HP

The Quincy QP Pro 10 HP compressor is built around a 120-gallon horizontal receiver and a two-stage cast-iron pump rated to 175 PSI, with particular attention paid to two components that directly affect long-term performance: stainless steel reed valves with valve bumpers and graphite cylinder and head gaskets. Quincy’s pressure-lubrication system adds a Gerotor positive-displacement oil pump and spin-on filter, with the manufacturer stating up to 15% longer service life than splash lubrication. This model is configured for 230V 3-phase power, so verify that your available electrical service matches before ordering.

The valve package is designed to handle the repeated cycling of a two-stage pump. Stainless steel reeds provide fatigue resistance, while the valve bumpers help control reed movement as each valve opens and closes. That matters in daily operation because worn or damaged valves can reduce the amount of compressed air the pump actually delivers and force the compressor to run longer. The graphite gaskets provide the sealing needed at the cylinder and head joints as temperatures rise and fall during operation. A fin-and-tube intercooler helps reduce heat between stages, while the balanced cast-iron flywheel also moves cooling air across the pump. Together, these features support efficient compression and consistent sealing under working pressure.

This compressor is a strong fit for established automotive service shops, machine and fabrication operations, body shops, and multi-bay workshops that already have 230V 3-phase service and need a large receiver for sustained air demand. Its horizontal configuration measures 78" long × 28" wide × 55" high and weighs 995 lbs, making floor space and equipment access important considerations. Plan for adequate room around the pump for maintenance and keep the fan side unobstructed for cooling airflow. A 1" discharge outlet is provided for hard-piped air distribution.

Why the Valves Matter

The stainless steel reed valves open and close on every pump stroke, so fatigue resistance matters over millions of cycles. Valve bumpers help control reed movement and reduce impact against the valve seat.

Valve condition directly affects volumetric efficiency — how much of the air the pistons displace actually gets delivered. As valves wear, the compressor may run longer to produce the same output, making valve design an important long-term consideration.

Sealing Under Pressure

Graphite cylinder and head gaskets are designed to handle the heat and pressure of two-stage compression up to 175 PSI while tolerating repeated thermal cycling.

The balanced cast-iron flywheel also functions as a cooling fan, moving air across the intercooler, cylinders and heads. The fin-and-tube intercooler reduces temperature between compression stages, helping the second stage compress cooler, denser air.

The QP Pro lubrication system uses a Gerotor positive-displacement oil pump to pressure-lubricate the crankshaft, bearings and connecting rods, with a spin-on oil filter in the circuit. Quincy rates the system at up to 15% longer service life than splash lubrication.

Will It Fit?

• Receiver: Horizontal, 120 gallons
• Dimensions: 78" L × 28" W × 55" H
• Weight: 995 lbs
• Outlet: 1" discharge
• Service clearance: Leave room around the pump for belt and filter maintenance and keep the fan side clear for airflow.
• Power: 230V three-phase. Verify your actual supply before ordering.
• Starter: Magnetic starter included. Breaker and conductor sizing should be determined by a certified electrician.

Confirm the power supply, doorway width, floor capacity and delivery route before ordering.

Perfect For

• Service shops with 230V three-phase power
• Machine and fabrication shops with demanding duty cycles
• Body and refinishing shops requiring consistent air delivery
• Multi-bay workshops supplying a hard-piped ring main from one large receiver

What Arrives

Factory-assembled compressor with two-stage cast-iron pump, motor, horizontal 120-gallon receiver, Gerotor oil pump, spin-on oil filter, stainless steel reed valves and bumpers, graphite gaskets, balanced cast-iron flywheel and fin-and-tube intercooler.

Compressor oil, hose, air treatment, regulator and isolation valve are not listed as included. Plan these as separate purchases unless confirmed otherwise before ordering.

Specifications

One Rating to Confirm Before You Order

Published motor specifications conflict. The product title, page description and model designation identify this as a 15 HP compressor, while one specification field lists a smaller motor rating and a free air delivery figure consistent with that lower-rated machine. The corresponding field on the higher-voltage version lists 15 HP, suggesting the smaller rating may be an outlier.

Because Quincy has not yet confirmed the discrepancy, verify the motor rating and rated air delivery with us in writing before ordering, especially if your electrician is sizing the electrical service around them.

Certification, Stated Plainly

The specification sheet records ASME, UL and CSA marks. Their scopes are different:

• ASME: Applies to the pressure vessel/receiver and its construction.
• UL/CSA: Apply to the applicable electrical components, not automatically to the complete machine.
• Installation: These marks do not replace local permitting, registration or inspection requirements.

Check your local requirements before installation, particularly if the receiver is subject to pressure-vessel inspection.

Shipping & Delivery

Ships by freight within the lower 48 states, with the rate calculated at checkout for your delivery address. This is a heavy industrial compressor, so plan for appropriate unloading equipment such as a forklift, dock or telehandler, or arrange terminal pickup.

Residential delivery carries an additional fee.

Inspect the pallet and compressor before signing. Check the guards, gauges, wrapping and receiver for visible damage, and record any issues on the bill of lading while the driver is present.

Warranty

Includes a 1-year Quincy factory warranty, with an extension available when the unit is registered and serviced using the required Quincy maintenance kit listed in the specifications.

Register the compressor promptly after delivery. If a problem occurs, contact us before disassembling the compressor. Keep the unit intact and document the condition before beginning repairs.
