Quincy Air Compressor Pro 15 HP 120 Gallon Two Stage 460V 3 Phase

The Quincy 4153DS12HCA46 is a 15 HP reciprocating compressor built for shops that need high airflow while keeping oil carry-over controlled. Quincy specifies less than 5 PPM oil blow-by, giving operators a clear number to evaluate when compressed air quality matters. Behind that specification is a cast iron four-cylinder two-stage pump rated for more than 50,000 hours of service, paired with a Baldor industrial-duty motor, a 120-gallon horizontal ASME receiver, and output of 51 CFM at 175 PSI. A 1-inch ball valve outlet helps support the airflow this compressor is designed to deliver without adding unnecessary restriction at the tank connection.

The low oil carry-over rating helps reduce contamination reaching downstream equipment and reduces the workload placed on filtration systems. For applications such as paint spraying, plasma cutting, and abrasive blasting, excess oil in compressed air can affect results, increase maintenance costs, and shorten filter life. The less than 5 PPM figure does not make this an oil-free compressor, but it does mean a properly sized filtration system can manage the remaining carry-over instead of compensating for excessive oil output. The two-stage design and 120-gallon receiver also help the pump operate in longer, cooler cycles by absorbing demand changes and reducing unnecessary starts.

This compressor is designed for professional repair facilities, fabrication shops, body shops, and industrial applications that require 51 CFM of air at 175 PSI. The horizontal tank configuration works well in locations where ceiling height limits equipment options, while the 460V three-phase motor makes it suited for commercial electrical systems. The factory-mounted magnetic starter simplifies installation, while the final electrical requirements should be matched to the building supply by a qualified electrician.

Oil Carry-Over: Why It Matters

Oil carry-over is the small amount of lubricating oil that can enter the compressed-air stream. It matters most in three areas: paint quality, filter life and downstream piping.

The published figure of less than 5 PPM indicates low oil carry-over, but this is still an oil-lubricated reciprocating compressor, not an oil-free machine. Applications requiring genuinely oil-free air—such as breathing air, certain food-contact processes, or some medical and laboratory applications—require a different compressor technology.

If you have a specific air-quality requirement, confirm it before purchase.

Match the Piping to the Outlet

The compressor has a 1" tank outlet. Properly sized piping helps minimize pressure drop between the receiver and the point of use, especially at higher flow rates.

The 120-gallon receiver does not increase compressor output, but it provides stored air capacity to handle demand fluctuations and reduce frequent pump cycling.

Will It Fit?

This horizontal compressor measures approximately:

• 78" L × 28" W × 55" H
• 995 lbs
• 120-gallon horizontal receiver

The horizontal design works well where ceiling height is limited, including locations under mezzanines, overhead door tracks or along walls. The tradeoff is greater floor-space requirements than a comparable vertical receiver.

Install on level, solid concrete with adequate clearance for cooling airflow and access to the belt guard, oil sight glass and drain. Confirm the installation pad, service clearances and delivery route before ordering.

Electrical Requirements

Requires 460V, 3-phase power. The industrial-duty magnetic starter is factory mounted and wired, so the installation requires an appropriate electrical supply rather than a separate control-panel build.

Quincy does not publish a specific breaker size for this unit. Have a qualified electrician determine conductor sizing and overcurrent protection based on the installation and applicable local code.

Perfect For

• Body and paint shops requiring low oil carry-over and up to 175 PSI
• Fabrication and plasma cutting with steady compressed-air demand
• Multi-bay service shops using multiple pneumatic tools
• Light manufacturing with 460V, 3-phase power and consistent air demand

What's Included

The compressor ships factory assembled with:

• Pump, motor and belt drive with guard
• 120-gallon horizontal receiver
• Industrial-duty magnetic starter, factory mounted and wired
• Quincy warranty documentation

Specifications

Certification, Stated Clearly

The manufacturer’s certification information lists an ASME tank with UL and CSA markings. These certifications apply to the equipment and their respective areas of scope; they do not certify your site installation.

Electrical supply, disconnects, overcurrent protection and ventilation must meet applicable local requirements and should be reviewed by a qualified electrician. If an insurer, landlord or authority having jurisdiction requires specific compliance documentation, request the manufacturer’s records before ordering.

Shipping & Delivery

Ships by freight to the lower 48 states, with the rate calculated at checkout based on your delivery ZIP code. Residential deliveries may incur an additional fee. Commercial delivery with a dock or forklift, or freight-terminal pickup, may be more practical for this unit.

Unloading is the customer’s responsibility. At approximately 995 lbs, arrange suitable equipment to safely unload the compressor.

Inspect the crate and compressor before signing. Check the tank, pump, motor and belt guard, and document any visible damage on the bill of lading with the driver present.

Warranty

The compressor includes a 1-year factory warranty and may qualify for Quincy’s extended 3-year “No Bull” warranty when the manufacturer’s registration and maintenance requirements are met.

Confirm the current extension requirements before relying on the additional coverage.

If a failure occurs, contact us before disassembling the pump, motor or starter. Keep the components intact and document the issue with photos so the warranty claim can be evaluated properly.
