The 10 HP oil-injected rotary screw compressor delivers 38.8 CFM at 125 PSI on a continuous 100% duty cycle, giving shops a steady supply of compressed air without the rest periods required by duty-limited piston compressors. It pairs the rotary screw airend with a 120-gallon receiver, TEFC motor, and long-life V-belt drive for demanding applications. The unit runs on 208V, 230V, or 460V three-phase power and measures 76" L × 25" W × 58" H. Note: site wiring must be completed by a licensed electrician.
The rotary screw design uses continuously rotating rotors rather than reciprocating pistons, reducing vibration while allowing the compressor to run continuously. Auto-Dual control adds flexibility by allowing a timed shutdown when there is no air demand, helping avoid unnecessary energy use during idle periods. The system also uses premium synthetic lubricant rated for up to 8,000 hours, helping extend service intervals while maintaining low oil carryover and reducing the load on downstream air filtration.
This compressor is well suited for multi-bay automotive and tire shops, light manufacturing facilities, production areas, and other operations where compressed air demand is frequent or continuous. It is also a practical upgrade for shops moving away from duty-limited piston compressors and for facilities with changing work schedules that can benefit from adjustable automatic shutdown. With its compact footprint and continuous-duty design, it provides a dependable compressed-air source for applications where pressure availability throughout the workday matters.
Auto-Dual Control: More Than an On/Off Switch
The unit features Auto-Dual control, allowing you to set a timed shutdown instead of leaving the compressor running indefinitely between periods of demand.
A rotary screw compressor still consumes significant power while running unloaded — the airend and cooling fan continue operating even when no compressed air is being delivered. In a shop with irregular demand, Auto-Dual lets you set the compressor to shut down automatically after a defined period without air usage, helping reduce unnecessary energy consumption.
For shops with steady demand, the shutdown interval can simply be set longer so the compressor remains available and ready to respond. One control system accommodates two very different operating profiles, giving you control over how the compressor runs.
Why a Screw Compressor Is Designed for Continuous Operation
Unlike a reciprocating compressor, where the piston repeatedly changes direction on every stroke, a rotary screw compressor uses two rotors that turn continuously in the same direction. Oil is injected into the compression chamber to seal, cool, and lubricate the rotors during operation.
Because there is no constant start-stop reversal of a piston, the compressor produces less vibration and is designed for sustained operation. This contributes to a 100% duty-cycle rating, making continuous operation a fundamental part of the machine's design rather than simply a performance figure.
Lubrication and Downstream Air Cleanliness
The compressor uses premium synthetic lubricant rated for up to 8,000 hours. This helps extend service intervals while maintaining effective lubrication and cooling of the airend.
Proper oil separation also helps minimize oil carryover into the compressed-air stream. Lower carryover can reduce the burden on downstream filtration and help deliver cleaner air to your tools and equipment.
Will It Fit?
-
Footprint: 76" L × 25" W. The relatively narrow footprint provides substantial airflow output without consuming excessive floor space. However, adequate clearance must be maintained around the cooling-air intake, exhaust, and service areas.
-
Height: 58" overall.
-
Weight: 775 lbs.
-
Power: Three-phase, 208V, 230V, or 460V. Quincy does not publish a specific amp draw or breaker size for this configuration and specifies that the unit must be wired on site by a licensed electrician. Electrical requirements should therefore be confirmed before delivery.
-
Air Connection: 1/2" tank outlet. Properly sizing the shop's air piping is important, particularly on longer runs, where undersized piping can create unnecessary pressure loss.
The customer is responsible for the slab, electrical feed, disconnect, on-site wiring, compressed-air piping, and condensate management.
Perfect For
-
Multi-bay automotive and tire shops where compressed-air demand is frequent and recovery time affects productivity.
-
Light manufacturing and production environments using pneumatic tools, equipment, or actuators.
-
Facilities replacing a duty-limited reciprocating compressor that need more consistent air availability.
-
Shops with variable operating schedules where Auto-Dual's timed shutdown can be adjusted to match actual demand.

Certification, Honestly
Our records list one certification for this unit: the ASME pressure-vessel code for the receiver tank. This is a legitimate third-party construction and testing standard for the pressure vessel itself. It should not be interpreted as certification of the compressor's electrical assembly, controls, or enclosure.
We have no record of an additional third-party safety listing for this machine, and we will not imply otherwise.
This distinction can matter when installing permanently mounted shop equipment. Certain insurers, fleet policies, or local authorities may require a specific third-party safety listing before approving an installation. If that applies to your facility, determine exactly which certification or listing is required and verify that it matches the unit's data plate and factory documentation before purchasing.
Before You Order — Please Confirm
-
Whether an air dryer is fitted. This is the most important point to confirm on this listing. The product feature list references an integrated refrigerated air dryer, while our specification record for the same unit states “No” for the air dryer. Those two records cannot both be correct. A dryer is not a minor detail — it affects the purchase price, footprint, condensate management, and whether the compressed air is suitable for applications such as painting. For that reason, we are not claiming that a dryer is included, nor are we claiming that it is absent. If dry air is a requirement for your application, contact us and we will verify the exact factory configuration against the order documentation before the unit ships.
-
Sound level. The enclosed design is intended to help reduce operating noise, and current product information describes the machine as quiet. However, the decibel figure in our available data is not documented with a verifiable measurement standard or test condition, so we are not publishing a specific noise rating. If your installation has a required sound limit, contact us before ordering so we can determine what documentation is available.
Shipping and Delivery
Freight to the lower 48 states is quoted live at checkout based on your delivery address.
The compressor ships as a 775-lb palletized unit, so make sure the unloading method is arranged before delivery. Depending on your location and facility, you may need a forklift, loading dock, or carrier-terminal pickup.
Residential deliveries may incur an additional residential delivery fee, which will be reflected in the freight quote at checkout.
Inspect the shipment immediately upon arrival. Check the enclosure panels, receiver tank, feet, controls, and other accessible components for visible damage. If you find damage, document it and have it noted on the bill of lading before signing for the shipment. A clean delivery receipt can make a later freight-damage claim substantially more difficult.
Warranty
There are three warranty levels associated with this compressor, and the standard factory warranty is the one included automatically:
-
Standard factory warranty: 1 year
-
Extended factory warranty: 3 years, available as an option
-
True Blue 5-year warranty: Available when the compressor receives a Quincy-authorized start-up
The 5-year warranty is conditional on the authorized start-up; it is not simply an automatic upgrade that can be added after installation. If the extended coverage is important to you, arrange the authorized start-up as part of the installation process.
For any warranty-related issue, contact us before opening the enclosure or disassembling the compressor. Do not remove or service the airend before the claim has been reviewed. Unauthorized disassembly can affect warranty coverage and may make it more difficult to determine the cause of a failure.
