The Chicago Pneumatic QRS3.0HPD-3 is a 3 HP rotary screw compressor built for facilities that need a continuous supply of compressed air rather than high output in short bursts. It delivers 8.5 CFM at 150 PSI, is rated for a 100% duty cycle, and combines a TEFC Baldor motor, integrated air dryer, and 60-gallon ASME/CRN receiver in a low-sound package operating at 61 dBA. Its 208-230/460V three-phase motor can be configured for the electrical service available at the installation, making this a practical choice for permanent utility-air applications.
The main advantage is the combination of continuous-duty screw compression and integrated drying. The rotary screw airend can operate continuously without the rest periods required by a comparable reciprocating compressor, which makes it better suited to applications with modest but sustained air consumption. The built-in dryer removes the need to add a separate drying system, helping keep moisture away from pneumatic controls, tools, and equipment. Start/stop control is used instead of the load/no-load system found on larger models, allowing the compressor to stop when air demand ends rather than continuing to run without producing useful air. The UL- and cUL-approved control panel and named Baldor motor add clearly identified electrical and drive components to the package.
This model is suited to plant rooms, utility spaces, fabrication areas, cutting tables, instrument-air applications, and other facilities where air demand is relatively low but may continue throughout the workday. The 61 dBA operating level also makes it appropriate for locations where compressor noise needs to be controlled. The ASME/CRN receiver is useful for installations that require a registered pressure vessel, while the dual-voltage three-phase motor offers flexibility when the facility's electrical service changes. Buyers should confirm the required voltage configuration, installation clearances, ventilation, and electrical requirements before commissioning.

Approvals, Stated Plainly
The product data lists two approvals: UL and cUL for the control panel and ASME/CRN for the receiver. The first covers the electrical side; the second covers the pressure vessel.
The available data does not list any additional agency certification or third-party mark for the complete machine. If your insurer, safety program or project specifications require documentation beyond these approvals, contact us before ordering and we will confirm what the manufacturer can provide in writing.
Shipping & Delivery
Ships by palletized freight to the lower 48 states, with shipping quoted live at checkout based on your delivery address.
At approximately 452 lbs, plan for a forklift, loading dock or terminal pickup. Residential deliveries may incur an additional fee.
Inspect before signing. Check the enclosure, cooler and accessible areas for damage, including along enclosure edges and under panels where possible. Record any damage or shortages on the bill of lading while the driver is present and take photographs.
Warranty
The listing states a 5-Year warranty, conditional on an authorized start-up, and directs buyers to contact us for the specific terms.
If you need the warranty conditions confirmed before purchase, contact us and we will obtain the current details in writing.
If a fault occurs, do not disassemble the airend, dryer circuit or control panel before opening a warranty claim. Stop and isolate the machine, document the condition, and contact us before any work begins.
