Quincy Air Compressor 573DS80VCA23 QP Pro 7.5 HP 80 Gallon

The Quincy QP Pro 7.5 HP compressor combines pressure lubrication with a feature that makes routine service simpler: a spin-on oil filter. A Gerotor positive-displacement oil pump circulates pressurized oil through the crankshaft, bearings, and rods, allowing contaminants to be removed from the oil instead of continuously circulating through the pump. Quincy states that this system can provide up to 15% longer life than a splash-lubricated equivalent. This 230V 3-phase model uses a two-stage cast-iron pump, an 80-gallon vertical receiver, and a maximum working pressure of 175 PSI.

The pressure-lubrication system delivers a consistent oil supply as the crankshaft turns, while the spin-on filter captures wear particles in the circulating lubricant. An oil sight glass makes the level easy to check during routine inspections, helping identify low oil before it becomes a larger problem. The pump also uses stainless steel reed valves with valve bumpers and graphite cylinder and head gaskets. A fin-and-tube intercooler reduces temperature between compression stages, while the electronically balanced, fan-type cast-iron flywheel moves cooling air across the intercooler, cylinders, and heads. These systems work together to manage heat, sealing, lubrication, and repeated valve cycling during extended operation.

This compressor is suited to established repair shops, fleet and municipal workshops, machine shops, and fabrication facilities with 230V 3-phase service and regular compressed-air demand. The vertical 80-gallon receiver keeps the floor footprint to approximately 37" × 24", while the unit stands about 74" tall and weighs 720 lbs, so verify ceiling clearance and access before installation. The compressor is hard-wired rather than plug-in, and electrical protection should be sized by a certified electrician based on the actual installation. Allow sufficient clearance around the pump for belt, head, and maintenance access, and provide a flat, level, load-bearing installation surface.

Maintenance You Can Keep Up With

The QP Pro makes routine oil checks straightforward. An oil sight glass provides a quick level check, while the spin-on oil filter simplifies scheduled oil maintenance.

Keeping oil clean and at the correct level is essential to protecting the pump and maintaining reliable operation.

How the Oil Gets Where It Needs to Be

The Gerotor positive-displacement oil pump is driven by the crankshaft and delivers pressurized oil to the crankshaft, bearings and connecting rods.

Unlike splash lubrication, which relies on moving components to distribute oil through the crankcase, this system provides a dedicated pressurized oil circuit. Quincy states that its pressure-lubricated QP Pro pump can deliver up to 15% longer life than a splash-lubricated design.

Valves, Gaskets & Cooling

The pump uses stainless-steel reed valves with valve bumpers to control reed movement. Graphite cylinder and head gaskets provide sealing through normal operating temperature cycles.

Cast-iron cylinders feed a high-efficiency fin-and-tube intercooler, while the electronically balanced, fan-type cast-iron flywheel moves cooling air across the intercooler, cylinders and heads.

Interstage cooling helps control compressed-air temperature and improves two-stage compression efficiency before air reaches the receiver.

Will It Fit?

The 80-gallon vertical receiver requires a 37" × 24" footprint, stands 74" tall and weighs 720 lb. Allow additional clearance around the pump and belt guard for inspection and service.

This model operates on 230V three-phase power and is hard-wired rather than plug-connected. A magnetic starter is included. Have a qualified electrician verify the required breaker, conductors, disconnect and installation requirements for your site.

• Repair shops with 230V three-phase service and regular air demand.
• Fleet and municipal workshops with scheduled maintenance programs.
• Machine shops and fabricators needing a pressure-lubricated pump.

Specifications

Certification, Stated Plainly

Quincy lists ASME marking for the receiver and CSA marking for the applicable electrical components. These address different requirements, and neither certifies your building’s electrical installation.

Verify the markings on the machine’s data plate when it arrives. If your local code, lease, insurer or inspector requires a specific listing, confirm that requirement before the compressor is wired.

Shipping & Delivery

Ships by freight carrier within the lower 48 states. At 720 lb, the pallet requires a forklift, loading dock or prearranged carrier-terminal pickup. Residential delivery carries an additional fee.

Inspect the shipment before signing. Check the guards, shroud, tank and bracing for damage or movement, and look for oil on the pallet. Record any damage or concerns on the bill of lading before signing.

Warranty

The compressor includes a 1-year factory warranty, with coverage extending to 3 years under Quincy’s “No Bull” warranty when the manufacturer’s conditions are met. These generally include purchasing the required maintenance kit with the compressor and registering the unit with Quincy. The supplied warranty documentation provides the definitive terms.

Do not disassemble the pump, motor or starter before opening a warranty claim and arranging inspection. Unauthorized disassembly may affect coverage.
