The Quincy QP Pro 7.5 HP compressor brings the QP Pro pressure-lubricated pump to a 230V single-phase power supply, making this industrial-style configuration practical for shops, garages, and properties without three-phase service. Quincy specifies an 80-amp breaker for this model, so confirm your panel and service capacity with an electrician before ordering. The pump uses a Gerotor positive-displacement oil system, cast-iron construction, and a vertical 80-gallon receiver rated to 175 PSI. Unlike many compressors in this power range, the pressure-lubrication system is designed for sustained operation rather than relying on splash lubrication.
The Gerotor pump sends pressurized oil directly to the crankshaft, bearings, and connecting rods on every revolution, while a spin-on filter removes contaminants from the circulating oil. Quincy states that this arrangement can provide up to 15% longer life than a comparable splash-lubricated pump. The two-stage design compresses air progressively to 175 PSI, with a fin-and-tube intercooler reducing temperature between stages. An electronically balanced, fan-type cast-iron flywheel moves cooling air across the intercooler, cylinders, and heads. Stainless steel reed valves use valve bumpers to control lift, while graphite cylinder and head gaskets are designed to maintain their seal through repeated heat cycling.
This compressor is a strong fit for independent automotive shops, serious home garages, agricultural properties, and enthusiast workshops that need extended compressed-air capacity but do not have three-phase power available. The vertical receiver occupies approximately 37" × 24" of floor space and the unit stands about 74" tall, with a total weight of 720 lbs. Verify ceiling clearance, access, floor loading, and ventilation before installation. The substantial electrical requirement also makes proper site preparation essential: the 80-amp circuit, conductors, and disconnect should be planned with a licensed electrician before the compressor arrives.
Check Your Panel First
A 7.5 HP single-phase motor draws significantly more current than a comparable three-phase motor, which is why this model requires an 80-amp breaker.
Before ordering, have an electrician confirm:
- An 80-amp breaker position is available.
- The service and panel can handle the added load.
- The correct conductor size for the actual run length.
If the panel needs an upgrade, it is better to know before a 720 lb compressor arrives. This is hard-wired equipment and must be installed by a qualified electrician. The circuit, disconnect, permits and site preparation are the customer’s responsibility.
A magnetic starter is included with thermal overload protection for the motor.
Pressure Lubrication on a Single-Phase Supply
The QP Pro pump uses a crankshaft-driven Gerotor positive-displacement oil pump to deliver pressurized oil to the crankshaft, bearings and connecting rods.
Quincy states that this pressure-lubricated design can provide up to 15% longer life than a splash-lubricated pump. A spin-on oil filter removes contaminants from the oil circuit, while the oil sight glass provides a quick level check.
Two-Stage Compression & Intercooling
The belt-driven pump uses cast-iron cylinders, an aluminum head and two-stage compression to 175 PSI.
Between stages, compressed air passes through a high-efficiency fin-and-tube intercooler. An electronically balanced, fan-type cast-iron flywheel moves cooling air across the intercooler, cylinders and heads.
Interstage cooling helps control discharge temperature and improves compression efficiency while reducing moisture carried into the receiver.
Valves & Gaskets
Stainless-steel reed valves use valve bumpers to limit lift and help control valve movement under operating conditions.
Graphite cylinder and head gaskets provide sealing through the repeated heating and cooling cycles of normal compressor operation.
Will It Fit?
The 80-gallon vertical receiver requires a 37" × 24" footprint, stands 74" tall and weighs 720 lb.
Verify ceiling height, doorways and delivery access before ordering. Leave adequate clearance around the pump and belt guard for inspection and service. Install the unit on a flat, level, load-bearing surface with access to the tank drain.
Perfect For
- Independent shops and single-bay garages without three-phase service.
- Home and enthusiast workshops with demanding air-tool use.
- Rural or agricultural properties without three-phase power.
-
Buyers who want QP Pro pressure lubrication in a single-phase configuration.

Certification, Stated Plainly
Quincy lists ASME and CSA markings for this compressor. The ASME marking applies to the pressure vessel, while CSA covers the applicable electrical components. Neither certification covers your building’s electrical service or installation.
Verify the markings on the unit’s data plate when it arrives. If your jurisdiction, insurer or landlord requires a specific listing for the complete installation, confirm that requirement before connecting the compressor.
Shipping & Delivery
Freight delivery is available in the lower 48 states. At 720 lb, this compressor requires a forklift, loading dock or prearranged carrier-terminal pickup. Residential delivery carries an additional fee.
Inspect the shipment before signing. Check the tank, guards, bracing and pallet for visible damage or oil, and record any 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 may include purchasing the required maintenance kit with the compressor and registering the unit with Quincy. Full terms are provided with the warranty documentation.
If a problem occurs, open the warranty claim before disassembling the pump. Unauthorized disassembly may affect warranty coverage.
