The Quincy QT Pro 7.5 HP compressor delivers 22.6 CFM at 175 PSI from an 80-gallon horizontal receiver, with a 100% duty cycle for demanding, continuous-use applications. This version is specifically built for 230V 3-phase power—the motor is not multi-voltage, so the available phase-to-phase supply must match the compressor's nameplate voltage before ordering. The horizontal tank measures approximately 70" L × 23" W × 47" H, making it a practical option where ceiling height is limited.
The two-stage cast iron pump uses a large first-stage cylinder, finned intercooler, and smaller second-stage cylinder to compress air in two steps while reducing heat between stages. A heavy cast iron flywheel helps cool the pump and smooth operation, while the belt drive keeps pump speed below motor speed. Combined with splash lubrication and a 100% duty cycle, this design is suited to sustained air demand rather than short bursts. A magnetic starter is included, while site-specific electrical protection and circuit sizing should be determined by a qualified electrician.
This compressor is a strong choice for established automotive repair shops, multi-bay service facilities, paint and body operations, and metal fabrication shops running multiple air tools or equipment for extended periods. The horizontal configuration is also useful in buildings with low ceilings, mezzanines, or overhead ductwork. Allow additional room around the approximately 740-lb unit for ventilation, service access, and belt-guard removal. The 3/4" tank outlet provides the starting point for your shop's air piping and distribution system.
Why 460V?
The compressor delivers the same output as lower-voltage versions of the pump. The difference is electrical: at the same output, a 460V motor draws less current, which can reduce conductor size and voltage drop on long runs.
Quincy does not publish a fixed current draw or breaker size for this model and recommends consulting a certified electrician. A magnetic starter is included. The motor winding is fixed at 460V and cannot be reconfigured for lower voltage, so confirm your supply before ordering.
What 22.6 CFM Supports
The pump supplies air; the receiver stores it. Size the compressor based on the continuous consumption of tools you expect to run simultaneously, then leave headroom above that total and compare it with 22.6 CFM.
Intermittent tools such as impact wrenches and blow guns typically use less air over time. Continuous-demand tools such as sanders, blast cabinets, and plasma equipment can consume most or all of the compressor's output.
The 175 PSI maximum pressure also provides a larger stored-air reserve than the same tank operating at a lower pressure.
How It's Built
The two-stage pump uses a high-efficiency finned intercooler, cast-iron cylinders, an aluminum head, a balanced cast-iron flywheel, belt drive, and splash lubrication.
The belt drive keeps pump speed below motor speed, while the intercooler manages heat between stages. This heavy-duty design is built for long industrial service.
Siting & Installation
Allow the footprint plus service access and approximately 74" of height. Check overhead clearance for ducting, lighting, sprinklers, mezzanines, and belt-guard service.
At approximately 740 lb, the compressor requires a level, load-bearing concrete surface, proper securing, and adequate airflow around the pump and heads. The tank outlet is 3/4".
The buyer is responsible for confirming the electrical supply and providing the circuit, disconnect, protection, and suitable installation surface.

Certification, Stated Plainly
Quincy lists ASME certification for the pressure vessel and UL and CSA recognition for the electrical components. These cover the tank and electrical equipment, not your installation, and do not replace local, insurer, or site-specific requirements.
If a specific listing or filing is required, verify it against the data plate before ordering. We can provide the manufacturer documentation published by Quincy.
Warranty
The compressor includes a 1-Year factory warranty and may qualify for Quincy's 3-Year “No Bull” warranty, subject to the manufacturer's conditions, including registration. We'll confirm the requirements for this model before purchase.

Freight & Delivery
Ships by palletized freight throughout the lower 48. Plan for a forklift or pallet jack, or arrange terminal pickup with a suitable trailer. Residential delivery carries an additional fee. Freight is calculated at checkout based on your delivery address.
Inspect before signing. Check the tank, guard, motor, gauges, and pallet. Record any damage on the bill of lading with the driver present. A clean signed receipt can make freight claims difficult.
