The Quincy QP Pro 10 HP compressor combines a pressure-lubricated two-stage cast-iron pump with a 120-gallon vertical receiver rated to 175 PSI. Its key differentiator is the Gerotor positive-displacement oil pump, which continuously feeds pressurized oil to the crankshaft, bearings, and connecting rods. Quincy states that this system can provide up to 15% longer life compared with splash lubrication. This version runs on 460V 3-phase power and uses a compact vertical footprint of approximately 40" × 30", with an overall height of about 75". Note: the product data contains two model numbers—5103DS12VCA46 and 3103DS12VCA46—so confirm the exact part number before ordering.
The pressure-lubrication system delivers oil directly to critical moving components rather than relying on oil being thrown around the crankcase. A spin-on oil filter removes wear particles from the circulating lubricant, while the oil sight glass makes routine level checks straightforward. The two-stage pump uses cast-iron cylinders and aluminum heads, with the two-stage design allowing the compressor to reach its 175 PSI maximum working pressure efficiently. The 460V 3-phase configuration can also reduce current requirements compared with lower-voltage versions, potentially simplifying the electrical installation where 460V service is already available.
This compressor is designed for manufacturing facilities, larger industrial shops, and other demanding operations that value pump longevity and continuous-duty reliability. It is particularly suited to buyers willing to invest in pressure lubrication and follow the required oil and filter maintenance to take advantage of the manufacturer's stated life-extension claim. At approximately 850 lbs and 75" tall, it requires a level concrete pad, adequate ceiling and doorway clearance, proper ventilation, and service access around the machine. Electrical feeder and disconnect sizing should be determined by a certified electrician based on the actual installation.
Before You Order: Two Model Codes in Our Data
This product appears under two model codes in our records:
-
5103DS12VCA46 — listed in the product title, description and specifications
-
3103DS12VCA46 — shown in the web address
We will not guess which is the current part number. Send us the code on your quote or purchase order, and we will confirm the exact build with the manufacturer before production.
What the 15% Claim Means
The 15% claim compares this pressure-lubricated design with a splash-lubricated compressor. Because the comparison method is not published, treat it as a manufacturer design claim, not a guaranteed increase in service life.
A Gerotor oil pump delivers oil under pressure from startup, while a spin-on oil filter removes contaminants from the circulating oil. The oil sight glass makes level checks easy.
The claimed benefit depends on proper maintenance, so follow the recommended oil and filter service intervals.
Why 460V
The 460V three-phase version is best suited to facilities that already have 460V service. Higher voltage means lower current for the same motor power, which can reduce conductor and feeder requirements.
Quincy lists breaker sizing as “consult a certified electrician.” Actual requirements depend on the installation, run length and local code. Confirm the feeder and disconnect before ordering; this build cannot simply be rewired to another voltage after delivery.

This is a planned industrial installation, not a typical home-garage compressor.
What’s in the Box
Factory-assembled package including the pressure-lubricated two-stage pump, motor, belt drive and guard, 120-gallon vertical receiver, Gerotor oil pump, spin-on oil filter, oil sight glass and magnetic starter. Warranty documentation is included.
Not included: electrical feed, disconnect, overcurrent protection, piping beyond the 3/4" tank outlet, downstream filtration or drying, isolation pads, or replacement oil and filter. No aftercooler or air dryer is fitted.
Certification, Stated Honestly
Quincy records this unit with an ASME receiver and UL and CSA marks. These certifications apply to the equipment as manufactured and do not certify the installation around it.
Electrical installation, ventilation and any required permits or inspections are the customer’s responsibility. If your insurer, landlord or local authority requires specific certification documents, ask us before ordering and we can obtain the applicable factory documentation.
Shipping & Delivery
Ships by freight within the lower 48 states, with the rate calculated at checkout based on your ZIP code. Residential delivery adds a residential fee. Commercial delivery with a dock or forklift, or terminal pickup, may reduce handling requirements.
The 850 lb palletized unit requires appropriate unloading equipment. Arrange a forklift, loading dock or suitable terminal pickup before delivery.
Inspect the crate, tank, pump and motor before signing. Record any damage on the bill of lading while the driver is present.
Warranty
Includes a 1-year factory warranty. Quincy’s warranty documentation provides the coverage terms and registration requirements; contact us if you want the documentation before purchase.
If a fault occurs, contact us before disassembling the pump, motor or starter. Photograph the condition and keep all components intact until the warranty claim has been reviewed.
