Quincy Air Compressor Q12124PQ 2 HP 24 Gallon Portable

The Quincy QT Pro 7.5 HP compressor is built for facilities with 460V three-phase power, using the same cast iron two-stage pump and 80-gallon horizontal receiver found across this family. The fixed-voltage motor is the key reason to choose this version: it must be matched to the available electrical supply before ordering. Quincy rates the compressor for a 100% duty cycle and 175 PSI maximum pressure, making it suitable for applications that require sustained compressed air throughout the workday. The factory-supplied magnetic starter provides the motor switching and protection system for the installation.

The two-stage pump is designed to handle continuous operation through a combination of slow pump speed and effective heat management. Air is cooled between the first and second compression stages by a finned-tube intercooler, while the aluminum head helps dissipate heat and the large balanced cast iron flywheel provides smooth operation while directing cooling air across the pump. Industrial-class bearings, graphite gaskets, and stainless steel reed valves support the pump through repeated operating cycles. Quincy rates this pump family for more than 50,000 hours of service when properly maintained. The 460V configuration also reduces current requirements compared with lower-voltage versions performing the same work, which can be useful on installations with long electrical runs.

This compressor is a practical fit for industrial plants, manufacturing and fabrication facilities, fleet garages, and larger workshops already equipped with 460V three-phase service. Its horizontal 80-gallon receiver creates a low-profile package that stands approximately 47 inches tall, making it useful where overhead clearance is limited. The unit requires a properly matched 460V three-phase supply, solid level concrete, and adequate clearance for cooling airflow and service access. Quincy does not provide a verified delivered-air figure for this specific build in the supplied information, so airflow at a stated pressure should be confirmed before ordering if CFM is a deciding factor.

Will It Fit?

At 36.4" L × 16.7" W × 22.6" H and 148 lbs, this horizontal compressor fits easily under benches or along a wall where a vertical tank may not. The wheels and handle are for moving it across a level floor—not lifting it into a truck or up steps.

Electrical supply is 115V AC, 1-phase, with a recommended 30A breaker. No magnetic starter is included. The customer is responsible for providing a properly sized dedicated circuit. If you are unsure, have an electrician verify the installation requirements.

Pump Construction

The pump uses a cast iron cylinder, valve plate and crankshaft, with an aluminum head and cooling fins. Quincy rates the pump for up to 10,000 hours of service life.

It is belt-driven and oil-lubricated, with an oil sight glass for quick level checks. The fully enclosed belt guard helps protect operators around the moving equipment. Belt drive also allows the pump to operate at a lower speed than the motor, with routine belt inspection and maintenance required.

Air Output

• 8.3 CFM @ 40 PSI
• 7.4 CFM @ 100 PSI
• 135 PSI maximum

The 7.4 CFM rating at 100 PSI is suitable for intermittent-duty tools such as impact wrenches, nailers, ratchets and small die grinders, as well as light touch-up spraying.

For continuous-demand equipment such as large sanders or media blasters, this portable single-stage compressor is not the right match. Choose based on the actual CFM requirements of your tools.

Tank & Controls

The compressor includes a 24-gallon ASME horizontal receiver, automatic start/stop pressure switch, pressure regulator and gauge, 1/4" outlet, oil sight glass and manual tank drain.

There is no air dryer, aftercooler, electronic drain valve or pump low-oil shutoff. If your application requires dry air, plan for appropriate downstream filtration and air treatment.

Perfect For

• Home garages needing a capable single-phase compressor
• Light commercial and mobile work where portability matters
• Shops needing a movable secondary air source
• Users replacing an oil-free compressor with an oil-lubricated cast iron pump

Specifications

Motor and electrical supply

Pump and air delivery

Tank, size and weight

Certification, Stated Plainly

The specification block lists ASME for the receiver, along with UL and CSA for the electrical components. These are the certifications stated for the equipment; we will not imply coverage beyond the manufacturer’s documentation.

If your installation must meet a specific listing, fire code or insurance requirement, tell us before ordering so we can confirm the current Quincy documentation in writing.

Shipping & Receiving

Ships by palletized freight to the lower 48 states, with the freight rate calculated live at checkout for your address.

Plan unloading in advance. You will need a forklift, loading dock, or suitable equipment and assistance to unload the pallet. If that is not available, terminal pickup with an appropriate trailer is an alternative. Residential delivery is available and may include a residential fee.

Inspect the compressor before signing. Record any visible damage on the bill of lading with the driver present. Damage discovered after a clean delivery signature can be difficult to claim.

Warranty

The product page states a 1-Year factory warranty with a possible 3-Year Quincy “No Bull” warranty. However, the specification block separately lists both consumer and commercial coverage as 1 Year, so the available documentation does not clearly establish the longer term for this model.

If extended coverage is important, confirm the current warranty terms—including any registration, oil or service requirements—before ordering.

If the pump develops a problem, do not disassemble it before contacting us. Keep the pump assembled so the manufacturer can properly evaluate the failure and warranty claim.
