The 10 HP, 230V 3-phase compressor combines a two-stage cast-iron pump with a 120-gallon horizontal receiver and a factory-mounted air-cooled aftercooler. Rated for 100% continuous duty and driven by a 1,750 RPM industrial motor, it is built for shops that need sustained airflow rather than occasional bursts. The aftercooler is the key advantage: it reduces compressed-air temperature before the air reaches the receiver, allowing more moisture to condense at the compressor instead of traveling into your piping and tools. Note: requires 230V 3-phase power, and electrical circuit sizing should be handled by a certified electrician.
The cooling system uses a fin-and-tube intercooler between the compression stages to cool the air before it enters the high-pressure cylinder, while the mounted aftercooler provides a second stage of cooling after compression. This reduces the moisture load reaching downstream equipment and helps protect pneumatic tools and air lines from liquid water. For added protection, the compressor includes low-oil shutdown to stop the pump if lubrication drops too far, while the magnetic starter provides thermal overload protection for the motor. A spin-on oil filter, stainless steel reed valves, and graphite gaskets round out the pump's service-focused design.
This compressor is a strong fit for paint and refinishing shops, humid-climate workshops, multi-bay automotive facilities, and other operations with sustained air demand. It is especially useful when moisture control matters but you still want flexibility to select your own dryer and filtration downstream. The horizontal receiver measures approximately 78" L × 28" W × 55" H and weighs about 850 lbs before oil, so plan for adequate floor support, access for maintenance, and unobstructed cooling airflow before installation.
Water Control Starts at the Compressor
Compressed air carries moisture from the ambient air. As it cools, that moisture condenses in receivers and downstream piping, where it can damage tools, affect finishes and contribute to corrosion.
The air-cooled aftercooler removes heat before the air reaches the receiver, helping reduce the moisture load downstream. A high-efficiency fin-and-tube intercooler between the two compression stages also cools the air before the second stage, improving compression efficiency.
Cast-iron cylinders maintain their geometry through repeated temperature changes, supporting long-term pump service.
Protection That Shuts the Machine Down
A low-oil protection device shuts the compressor down when lubrication is insufficient, helping protect the pump from damage. The magnetic starter provides thermal overload protection for the motor, while the spin-on oil filter helps keep contaminants out of the lubrication system.
These protections matter on a machine designed for demanding operation, where preventing a fault is preferable to discovering it after damage occurs.
Will It Fit?
This configuration uses a horizontal 120-gallon receiver measuring 78" L × 28" W × 55" H and weighing 850 lbs before oil. Allow room for belt guard, sight glass and filter access, and keep cooling airflow unobstructed.
The tank outlet is 3/4" and maximum working pressure is 175 PSI.
Electrical supply is 230V, 3-phase. The magnetic starter is included. Breaker and conductor sizing should be determined by a certified electrician based on your actual installation. Confirm the electrical supply, access route, doorway clearance and floor capacity before ordering.
Perfect For
-
Paint and refinishing — where moisture can affect the finished product.
-
Humid climates and summer operation — higher moisture loads make air treatment more important.
-
230V three-phase workshops — central compressed-air distribution from a 120-gallon receiver.
-
Systems adding a dryer — aftercooling reduces the heat and moisture load reaching downstream treatment.

Two Details to Confirm Before Ordering
Two specifications appear differently across the published sources. We are showing both rather than guessing.
Pump lubrication. The manufacturer feature list and page description call this a fully pressure-lubricated system with a positive-displacement oil pump feeding the crankshaft, bearings and connecting rods. The specification data lists splash lubrication instead. These are different systems. If lubrication type matters to your purchase, ask us to confirm the as-shipped configuration with Quincy in writing before ordering.
Tank drain. The feature list and specification table state that an automatic electronic tank drain is included, while another specification line says it is not. We can confirm this with Quincy before you order.
These discrepancies do not change the published capacity, receiver, electrical supply or warranty.
Certification, Stated Plainly
The specification sheet records ASME, UL and CSA marks. Their scopes are different:
-
ASME applies to the pressure vessel/receiver.
-
UL and CSA apply to electrical components and controls.
- None certifies air quality or replaces local permitting or required pressure-vessel inspections.
Confirm your local, insurance and workplace requirements before installation.
Shipping & Delivery
Freight is available within the lower 48 states, with shipping calculated at checkout for your address.
Plan for unloading with a forklift or loading dock, or choose terminal pickup if neither is available. Residential deliveries incur a residential fee.
Inspect the shipment before signing. Photograph any damage and record it on the bill of lading while the driver is present.
Warranty
Quincy provides a 1-year factory warranty, with coverage extending to the 3-year No Bull warranty when the unit is registered with Quincy and maintained using Quincy kits.
Register promptly after delivery. If a problem occurs, contact us before disassembling the pump or starter. A dismantled machine can make proper diagnosis and warranty evaluation difficult.
