The QP MAX 10 HP vertical compressor combines a large, slow-running cast-iron pump with a 120-gallon receiver and a 100% continuous-duty rating. Operating at 1,750 RPM, the two-stage pump is designed to deliver sustained air with less heat and mechanical wear than a smaller, faster-running pump. This version is built for 460V 3-phase power and has a listed 14A draw, making it especially practical for facilities that already have 460V distribution. Note: the unit measures approximately 30" W × 40" D × 75" H, so ceiling clearance is critical.
The cooling system supports the continuous-duty design with a fin-and-tube intercooler between the compression stages and a mounted air-cooled aftercooler after the pump. The intercooler cools air before it enters the second stage, while the aftercooler lowers discharge temperature before the air reaches the receiver, helping moisture condense at the machine instead of throughout the shop piping. A magnetic starter with thermal overload, low-oil shutdown, oil sight glass, and spin-on oil filter provide straightforward protection for the motor and pump during extended operation.
This compressor is well suited to industrial facilities with existing 460V 3-phase service, production shops running compressed air throughout the workday, and space-constrained plant rooms with sufficient ceiling height. The vertical design keeps the 120-gallon receiver within a compact 30" × 40" footprint, while the 850-lb weight means the installation needs a level, suitable slab and appropriate anchoring. Plan access for the tank drain, pump maintenance, and cooling airflow. Air piping, filtration, regulators, disconnect, electrical feed, and condensate routing are handled separately.
460V and Installation Cost
Quincy lists this build at 14 A on 460V three-phase. The higher supply voltage keeps current low, which can reduce conductor, conduit, breaker and disconnect requirements compared with lower-voltage versions.
If your facility already has 460V service, this configuration is a natural fit. If it does not, compare the installation cost before adding a transformer for a single compressor.
Built for Continuous Duty
Continuous operation depends on effective cooling. This unit uses a fin-and-tube intercooler between the compression stages and a mounted air-cooled aftercooler downstream of the pump. The aftercooler lowers discharge temperature and helps condense moisture before air enters the receiver.
Protection includes a magnetic starter with thermal overload, low-oil shutdown, oil sight glass and spin-on oil filter for straightforward monitoring and maintenance.
Will It Fit?
-
Footprint: 30" W × 40" D
-
Height: 75" overall — check ceiling clearance, lighting, overhead services and door tracks.
-
Weight: 850 lbs. Install on a level slab; anchoring is strongly recommended.
-
Power: 460V three-phase, 14 A listed by Quincy. Breaker sizing is not published; a licensed electrician should size the installation for the actual run and local code.
-
Air outlet: 3/4" tank outlet.
-
Drainage: Plan for condensate from continuous operation and the aftercooler.
The customer is responsible for the slab, leveling, anchoring, electrical feed, disconnect, air piping and condensate routing. Electrical work should be completed by a licensed electrician.
Perfect For
-
Facilities with existing 460V three-phase service
- Operations running compressed air throughout the day
- Space-limited plant rooms with sufficient ceiling height
- Facilities replacing a compressor that struggles with continuous demand

Certification, Honestly
This unit’s records list ASME pressure-vessel code for the receiver and a CSA mark. ASME certification applies to the pressure vessel itself, not automatically to the complete machine. If your insurer, fleet policy, or local authority requires a specific equipment listing, verify the requirement against the machine’s data plate before ordering. We can help confirm the factory documentation.
Before You Order — Please Confirm
-
Lubrication: Published information conflicts between pressure lubrication and splash lubrication. We will confirm the lubrication method with the factory before you order.
-
Automatic tank drain: Records differ on whether an electronic automatic tank drain is fitted. Confirm if this feature is important to your installation.
-
Air delivery: No verified CFM figure is published for this specific build. We will provide the factory rating rather than substitute a figure from another model.
Shipping & Delivery
Ships by freight within the lower 48 states, with the rate calculated at checkout. The 850 lb palletized unit requires a forklift, loading dock, or carrier terminal pickup. Residential delivery adds a residential fee.
Inspect the tank, feet, guards, gauges and cooler before signing. Record any damage on the bill of lading with the driver present.
Warranty
Includes a 1-year factory warranty, extending to a 3-year “No Bull” warranty subject to the terms and conditions in Quincy’s warranty handbook.
If a problem occurs, contact us before opening or disassembling the pump. Unauthorized disassembly can affect warranty coverage.
