The Quincy QP Pro 5 HP is a two-stage, belt-driven compressor with an 80-gallon vertical receiver and a Gerotor positive-displacement oil pump that delivers pressurized lubrication to the crankshaft, bearings, and connecting rods. Quincy rates this pressure-lubricated design for up to 15% more pump life than a comparable splash-lubricated unit. This model is built for 208V three-phase power and 175 PSI maximum pressure, making it a practical choice for shops that put their compressor through long working cycles rather than occasional bursts. Note: published references differ on the exact model code and do not provide a complete, unit-qualified airflow figure, so confirm the data plate and delivered-air rating with us before ordering if those details are critical.
The Gerotor oil pump is the main difference between this QP Pro and a conventional splash-lubricated compressor. Instead of relying on rotating components to distribute oil through the crankcase, the positive-displacement pump maintains a pressurized oil supply as the compressor operates. A spin-on oil filter cleans the circulating oil, helping protect the crankshaft and bearings over extended service. The two-stage cast-iron pump compresses air in two steps to 175 PSI, with a finned intercooler reducing heat between stages. Stainless steel reed valves with bumpers help control valve lift, while graphite gaskets handle the repeated heat cycles generated during compression. An electronically balanced cast-iron fan-type flywheel also provides cooling airflow across the pump.
This compressor is suited to independent service shops, fabrication and body shops, dealerships, fleet facilities, and other commercial workspaces where compressed air is used throughout much of the day. Its vertical design keeps the footprint to approximately 37" × 24", while the roughly 74" overall height and 680-lb assembled weight require adequate clearance and a suitable floor. Because this model is specifically wound for 208V three-phase service, verify the voltage and phase at your electrical panel before purchase and have the circuit, disconnect, and overcurrent protection installed by a qualified electrician.
Two Details to Confirm First
Published references differ on the model number. The heading and specification record list 553DS80VCA20, while the page URL uses a different string. Send us the code from your quote or data plate and we’ll confirm the exact build in writing before shipment.
No verified airflow rating is published for this unit. A delivered-air figure appears without a unit of measure, so it should not be treated as a complete specification. If CFM at pressure matters to your purchase, ask us before ordering and we’ll confirm the current Quincy rating.
What Pressure Lubrication Adds
This model uses pressure lubrication with a Gerotor oil pump and spin-on oil filter. The pump actively circulates oil through the lubrication system, while the filter helps remove contaminants from the circulating oil.
That makes the system better suited to sustained compressor operation than a splash-only lubrication system. The spin-on filter also simplifies routine oil-service intervals.
Will It Fit & What Does It Need?
The vertical 80-gallon receiver keeps the footprint compact:
-
Footprint: approximately 37" × 24"
-
Height: approximately 74"
-
Weight: approximately 680 lbs
-
Outlet: 3/4"
-
Receiver: vertical
-
Installation: Level, stable surface; secure according to the manufacturer’s instructions
Allow service clearance above the machine for access to the belt guard and oil-fill area. Check doorways, ceiling obstructions, ducting and sprinkler clearance before ordering.
Power: 208V, three-phase. The motor is specified for this supply, and a magnetic starter is included. Quincy does not publish a fixed breaker size for this model; have a qualified electrician size the circuit and overcurrent protection for the installation.
Buyer responsibilities: Confirm incoming voltage and phase, provide the electrical circuit, disconnect and required protection, and prepare a suitable floor and installation site. Do not connect the compressor to a different voltage or phase.
Two-Stage Compression & Intercooling
The two-stage pump compresses air in sequence, with a fin-and-tube intercooler between stages. Cooling the air between compression stages helps manage operating temperature before the second stage raises pressure to the 175 PSI maximum rating.
The pump uses cast-iron cylinders, graphite cylinder and head gaskets, stainless steel reed valves with bumpers, and an electronically balanced cast-iron fan-type flywheel.
Perfect For
- Independent service shops with 208V three-phase power
- Fabrication and body shops with sustained compressed-air demand
- Fleet and dealership workshops replacing an older compressor
- Shops with limited floor space and sufficient ceiling height for a vertical receiver

Certification, Stated Plainly
Quincy’s specification sheet lists ASME for the pressure vessel and UL and CSA on the electrical side. These certifications serve different purposes and do not replace local inspection requirements.
If your insurer, jurisdiction or company policy requires a specific marking or pressure-vessel filing, verify the requirement against the machine’s data plate before ordering. We can provide the manufacturer’s published documentation for confirmation.
Warranty
The machine includes a 1-year factory warranty, with coverage extending to Quincy’s 3-year “No Bull” warranty when its conditions are met. The EWK-6 Maintenance Kit must be purchased with the compressor, and the unit must be registered with Quincy. Extended coverage includes on-site service and labor.
If a failure occurs, contact us before disassembling the pump. Keep the machine assembled so the manufacturer can properly assess the warranty claim.

Freight & Delivery
Freight shipment to the lower 48 states, palletized and heavy. Plan for a forklift, pallet jack and firm unloading surface. If your site lacks unloading equipment, terminal pickup with your own trailer is an alternative. Residential delivery carries an additional fee, with freight quoted live at checkout.
Inspect the pallet, tank and shroud before signing. Look for dents, crushed components and fork damage. Photograph anything questionable and record it on the bill of lading while the driver is present.
