The Quincy QT MAX 15 HP delivers 51 CFM at 175 PSI with a 100% continuous-duty rating, making it built for sustained shop air demand rather than short bursts. The package combines a 15 HP motor with a splash-lubricated, cast-iron two-stage pump, a 120-gallon horizontal receiver, and a conservative 1,750 RPM operating speed. Quincy rates the pump for more than 50,000 hours of service, giving this compressor the capacity and operating design needed when multiple air-powered tools may be running throughout the day.
The pump uses splash lubrication, with connecting-rod dippers circulating oil through the crankcase. This straightforward system reduces the number of components involved in lubrication, while the oil sight glass makes the level easy to check. A low-oil cutoff switch shuts the compressor down if the oil level becomes too low, helping protect the pump from damage. Heat management is also built around continuous operation: a high-efficiency finned intercooler cools the air between compression stages, while built-in air-cooled aftercoolers reduce discharge temperature before air enters the receiver and help remove moisture from the compressed air.
For electrical protection, the unit includes a magnetic starter with thermal overload protection and is designed for 208V three-phase power. The 15 HP motor draws 48.3 amps according to Quincy’s published information, while the 1-inch tank outlet provides the connection point for the shop’s compressed-air system. The QT MAX 15 HP is a strong fit for multi-bay automotive shops, dealerships, tire and fleet operations, fabrication facilities, and other professional environments where several technicians may depend on consistent air supply. Its 100% duty cycle makes it particularly useful for shops that have outgrown compressors that need frequent recovery periods.
Splash Lubrication
This is a splash-lubricated pump with a simple, low-component design. Connecting-rod dippers circulate oil through the crankcase, while the oil sight glass makes level checks easy and the low-oil cut-off protects the pump from damage.
Built for Heat Management
A finned intercooler cools air between compression stages, reducing second-stage workload and valve temperatures. Built-in air-cooled aftercoolers lower discharge temperature and condense much of the moisture before it reaches the tank and air system.
Motor Protection
A magnetic starter with thermal overload protection helps protect the three-phase motor from overload and phase-loss conditions. Combined with the low-oil cut-off, it provides protection against common compressor failures.

Certification, Honestly
The receiver is built to the ASME pressure-vessel code, and the specification record also lists CSA. These certifications apply to the tank, not necessarily the complete compressor assembly.
Before You Order — Please Confirm
-
Warranty: Published information shows two different warranty structures. One lists 1-year factory coverage extending to 3-year “No Bull” coverage. Another lists 1-year parts and labor, 2-year package and 3-year pump coverage, conditional on purchasing and registering an EWK-5 Maintenance Kit. Contact us to confirm the current factory terms in writing before ordering.
-
Automatic tank drain: Published specifications conflict on whether an electronic automatic drain is included. Confirm with us if this feature is important to you.
Shipping & Delivery
Ships by freight to the lower 48 states, with shipping calculated at checkout.
At 923 lbs, the unit requires a forklift, loading dock or terminal pickup. Residential deliveries incur an additional fee.
Inspect the compressor before signing and record any damage on the bill of lading while the driver is present.
Warranty
Because the published warranty terms conflict, confirm the applicable coverage before ordering. The baseline listed is 1-year factory coverage, with extended protection available under specific conditions.
