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.
How to Read the CFM Ratings
This compressor is rated at 14.6 CFM @ 40 PSI and 12.8 CFM @ 100 PSI. Always compare a tool’s air demand at the pressure where you will actually use it.
Maximum pressure is 135 PSI, with a regulator for setting outlet pressure. This is a single-stage pump designed for intermittent, varied-duty work rather than continuous high-demand production.
Electrical Requirements
The published voltage information conflicts: the product title and voltage field state 230V, while a separate motor field lists 130V.
Treat 230V, 1-phase as the working specification, but confirm the voltage with us before wiring or ordering a circuit. We will verify it against current Quincy documentation.
Quincy specifies a 30A breaker. Plan for a dedicated circuit, with conductor and protection sizing determined by your electrician and local code. No magnetic starter is included.
Pump Construction & Controls
The pump uses a cast iron cylinder, valve plate and crankshaft, with an aluminum finned head. Quincy rates the pump for 10,000+ hours of service life.
It is belt-driven and splash-lubricated, with an oil sight glass for routine checks and a fully enclosed belt guard.
A start-stop pressure switch starts the compressor as tank pressure drops and stops it when pressure recovers. The tank drain is manual; no electronic drain valve is included.
Each unit is factory tested at 100% of full pressure before shipment.
Will It Fit?
The 60-gallon vertical tank measures approximately 30" W × 22" D × 68" H and weighs 261 lbs.
Allow clearance above the tank and access to the gauges, regulator, oil sight glass and drain. Install it on a solid, level surface.
The outlet is 1/2". No air dryer or filtration is included.

Certification, Stated Plainly
The listing specifies a coded pressure vessel for the receiver, along with UL and CSA recognition for the electrical components.
These certifications apply to their respective components and do not represent a third-party safety listing for the complete machine as installed. If your insurer, fleet requirements or local inspector requires a specific listing, confirm that requirement with us before ordering.
Shipping & Receiving
Ships by palletized freight to the lower 48 states, with freight calculated live at checkout based on your delivery address.
Plan unloading before delivery. You will need a dock, forklift, or suitable pallet jack with a level unloading area. Terminal pickup is available if unloading equipment is not available at your location. Residential delivery is possible and may include an additional residential fee.
Inspect the compressor before signing. Check the pallet and packaging, photograph any damage, and record it on the bill of lading while the driver is present.
Warranty
The compressor includes a 1-Year factory warranty, with eligibility for Quincy's 3-Year “No Bull” warranty when the required maintenance kit is purchased with the machine. Extended coverage includes on-site service and labor, subject to Quincy's warranty terms and conditions.
Register the unit as required and review the warranty documentation before purchase. If any requirement is unclear, confirm it before ordering.
