The Quincy 7.5 HP rotary screw compressor brings 100% continuous-duty compressed air to buildings with 230V single-phase power, eliminating the need for a three-phase utility upgrade or rotary phase converter. It produces 21.2 CFM at 150 PSI according to the manufacturer's feature list, with a published specification also listing 21 CFM. Its 64 dBA sound level makes it substantially easier to operate around technicians and customers than a comparable reciprocating compressor. Note: published information lists the motor as both 7.5 HP and 8 HP, so confirm the current factory rating and delivered-air figure with us if either specification is critical to your installation.
The integrated refrigerated air dryer is a major advantage for shops that need usable compressed air without adding a separate drying system. Air leaving the screw element is hot and moisture-laden; the dryer removes that condensed moisture before it travels through the shop's piping and reaches tools or finishing equipment. The package also includes a 60-gallon horizontal receiver with a 3/4-inch outlet, providing storage to smooth changes in demand while giving the dryer a practical place to handle moisture removal. Start/stop controls with Wye-Delta starting manage operation, while the TEFC motor and factory-filled 8,000-hour lubricant support extended service intervals.
This compressor is built for independent automotive shops, two-bay service facilities, tire and fleet operations, and finishing businesses that need continuous air but only have single-phase electrical service. Cabinet, sign, and paint-related shops can benefit from the combination of steady screw-compressor output and integrated air drying, while serious home or collector garages with suitable 230V service can avoid the noise and cycling of a piston compressor. For installations where three-phase power is unavailable, this provides a way to use rotary screw technology without making a utility upgrade part of the project.
Air Delivery: Two Numbers to Confirm
The manufacturer’s feature list states 21.2 CFM at 150 PSI with a 100% duty cycle. The specification table lists 21 CFM, while both the feature list and model designation identify the motor as 7.5 HP and the specification table lists 8 HP.
These differences are small, but they are still discrepancies. If the exact CFM or horsepower matters for your installation, approval or equipment selection, contact us before ordering so we can confirm both against the current Quincy datasheet.
64 dBA: Quiet Operation
The rated sound level is 64 dBA. The rotary screw design and enclosed package make this a practical option when the compressor needs to operate near the workspace.
Integrated Dryer & 60-Gallon Receiver
An integrated refrigerated air dryer is included, helping remove moisture from compressed air before it reaches downstream equipment.
The package uses a 60-gallon horizontal receiver with a 3/4" outlet. The tank helps stabilize the air supply and supports the dryer during operation.
Controls use start/stop operation with Wye-Delta starting, and the motor is TEFC. The compressor ships factory-filled with lubricant rated for up to 8,000 hours.
Will It Fit?
The package is 56" long. Our current data does not provide verified width and height dimensions with units, so we will not publish unverified measurements.
Before ordering, confirm the complete footprint, doorway and access route with us.

What's Included
The manufacturer’s feature list includes:
- QGS rotary screw compressor
- 230V single-phase TEFC motor
- Integrated refrigerated air dryer
- 60-gallon horizontal receiver
- Start/stop controls with Wye-Delta start

An electronic drain valve is not listed, so plan on manual tank draining unless you install an automatic drain separately.
Shipping & Delivery
Quincy’s published feature list states free standard shipping to the lower 48, with a $75 charge when the delivery requires the machine to be lowered from the truck deck.
Our checkout provides the live freight rate for your delivery address. If that rate differs from the manufacturer’s published shipping term, contact us before ordering so we can confirm the cost in writing.
Residential deliveries carry an additional fee. Plan for a loading dock, forklift or terminal pickup, as this is not a hand-unload shipment.
Inspect the shipment before signing and record any damage on the bill of lading. A clean signature may be treated as confirmation that the shipment arrived intact.
Warranty
Standard coverage is 1 year. A 5-year extended warranty is available with a factory-authorized startup and must be arranged during installation.
True Blue 5-Year coverage applies to the airend, motor, sump and heat exchanger and is parts only; labor is not included.
If a fault occurs, shut the machine down and contact us before disassembling anything. Keep the compressor assembled for warranty evaluation.
