The Quincy QP Pro 10 HP is a horizontal air compressor built for shops where ceiling height is the limiting factor. At approximately 55 inches tall, its low-profile layout can fit beneath mezzanines, low ceilings, benches, or overhead door tracks where a vertical compressor cannot. It uses a fully pressure-lubricated two-stage pump with cast iron cylinders and aluminum heads, driven by a 10 HP motor on 208V three-phase power and rated to 175 PSI. Published information identifies the receiver inconsistently as either a 120-gallon horizontal tank or an 80-gallon vertical tank; the dimensions and model family align with the horizontal configuration, so tank size and orientation should be confirmed before ordering.
The horizontal design trades floor space for reduced overall height, making use of the long, narrow areas along a shop wall while keeping regularly serviced components within easier reach. The QP Pro pump uses pressure lubrication rather than splash lubrication, delivering oil to the bearings from the start of operation and allowing a spin-on filter to remove contaminants from the lubrication system. An oil sight glass provides a quick way to monitor the oil level. This arrangement is particularly useful for a compressor that may start and stop repeatedly throughout the workday, while the two-stage pump provides efficient compression to the 175 PSI operating rating.
This compressor is suited to automotive repair shops, fabrication facilities, fleet operations, and other professional shops that have sufficient floor space but limited overhead clearance. The published model code also varies between 5103DS12HCA20 and 3103DS12HCA20, so the exact code should be confirmed with your quote. The unit requires 208V three-phase power, solid level concrete, adequate cooling and service clearance, and an installation route capable of accommodating its horizontal dimensions and approximately 850-lb weight. Quincy specifies a magnetic starter but does not publish a breaker size, so the electrical installation should be sized by a qualified electrician according to the actual installation.
Two Things to Confirm Before You Order
Published information for this build differs in two areas. Please confirm both in writing before ordering.
Tank size and orientation: The description heading, specification fields and product record list a 120-gallon horizontal receiver, while one paragraph describes an 80-gallon vertical receiver. The published dimensions — approximately 78" L × 28" W × 55" H — and model family align with the horizontal configuration. If tank size or orientation matters to your installation, ask us to confirm it with Quincy before ordering.
Model code: The product title, heading and specifications list 5103DS12HCA20, while the page URL and one description reference 3103DS12HCA20. Send us the model code shown on your quote so we can confirm the exact build.
Why Choose a Horizontal Receiver?
A horizontal receiver uses more floor space but requires less overhead clearance. It also keeps the belt guard, oil sight glass, drain and outlet at a more accessible working height.
A vertical receiver of similar capacity generally uses less floor space but requires more ceiling height. Choose based on your available installation space.
Pressure Lubrication
The QP Pro pump uses pressure lubrication with an oil pump and spin-on oil filter. Oil is circulated through the lubrication system, while the filter helps remove contaminants before they continue through the system.
An oil sight glass provides a quick way to check the oil level.
Air Delivery — Confirm Before Ordering
Our specification record contains an air-delivery figure at 175 PSI, but the unit of measurement is not verified in the available data. We therefore do not publish the number on this page.
Ask us for the factory-rated CFM and we will confirm it in writing along with the tank configuration.
Installation Requirements
Install on a level, solid concrete surface with adequate clearance for cooling airflow and service access. The unit weighs approximately 850 lbs, so confirm that the floor and access route can accommodate it.
Because this is a long horizontal compressor, measure the delivery path carefully, including doorways and turns.
Electrical: 208V, 3-phase with a magnetic starter. Quincy does not publish a specific breaker size for this build and recommends consulting a certified electrician. Conductor sizing and overcurrent protection depend on the installation and applicable electrical code.
Customer responsibilities: floor preparation, clearance, delivery access and electrical installation.

Certification, Stated Clearly
Quincy’s records list an ASME receiver with UL and CSA markings for this unit. These certifications should be interpreted according to their specific scope and do not replace local installation requirements.
Electrical supply, disconnects, overcurrent protection and ventilation must meet applicable codes and be handled by a qualified electrician. If an insurer, landlord or authority requires specific documentation, request it before ordering. Given the tank configuration discrepancy noted above, we recommend confirming the factory documentation as part of the purchase.
Shipping & Delivery
Ships by freight to the lower 48 states, with the rate calculated at checkout based on your ZIP code. Residential deliveries may incur an additional fee. Commercial delivery with a dock or forklift, or freight-terminal pickup, may be more practical for a unit of this size.
Unloading is the customer’s responsibility. At approximately 850 lbs, the compressor requires appropriate unloading equipment such as a forklift, loading dock or equipped freight terminal.
Inspect the crate and compressor before signing. Check the tank, pump, motor and other visible components, and document any damage on the bill of lading with the driver present.
Warranty
The compressor includes a 1-year factory warranty. Warranty documentation supplied with the machine outlines coverage and any registration requirements; we can provide the terms before purchase.
If a fault occurs, contact us before disassembling the pump, motor or starter. Keep the components intact and document the issue with photos so the warranty claim can be evaluated properly.
