The Chicago Pneumatic QRS3.0HP-1 is a 3 HP rotary screw compressor that brings continuous-duty performance to shops with standard 230V single-phase power. It combines a TEFC Baldor motor with a rotary screw airend, a 60-gallon ASME/CRN horizontal tank, and a rated output of 8.5 CFM at 150 PSI. With a 100% duty cycle and operating noise of just 61 dBA, it offers a practical alternative to reciprocating compressors for smaller workshops that need sustained air without stepping up to three-phase electrical service.
The named Baldor motor is a useful advantage for long-term serviceability, while its TEFC enclosure protects the motor from the dust and debris common in working shops. The rotary screw airend is designed for continuous operation rather than the limited duty cycles typical of piston compressors. That means the compressor can keep supplying air during longer jobs without the same cooling pauses associated with reciprocating equipment. The low-sound enclosure also allows the unit to operate closer to the work area, which can simplify shop layout and reduce the distance compressed air needs to travel through the piping. Start/stop control runs the compressor when air is needed and stops it when demand ends.
This compressor is a strong fit for serious home garages, single-bay automotive shops, and small independent repair facilities that have 230V single-phase power but want rotary screw operation. It is particularly useful where compressor noise matters and where extended pneumatic-tool use makes a conventional piston compressor less practical. The 60-gallon receiver provides stored air capacity, while the 100% duty rating makes the QRS3.0HP-1 suitable for sustained shop use. The product information contains conflicting claims about whether an integrated air dryer is included, so that configuration should be confirmed before ordering.

| Electronic drain valve |
Not fitted |
No electronic drain means somebody opens the tank drain by hand on a schedule. Skip it for a year and the receiver corrodes from the inside, which is the one failure on a compressor of this class that is entirely preventable.
Approvals, and Exactly What They Cover
This product carries two separate approval claims. The control panel is UL and cUL approved, covering the electrical control equipment. The receiver is an ASME/CRN pressure vessel, covering the tank.
Neither constitutes a third-party safety listing for the complete compressor assembly. Electrical installation must comply with local code, and any applicable pressure-vessel inspection requirements remain the buyer's responsibility.
If your insurer, fleet policy or local authority requires specific documentation, contact us before ordering. We will confirm what documentation is supplied with this model.
Shipping and Delivery
Ships by palletized freight to the lower 48 states, with shipping quoted live at checkout based on your delivery address.
The unit weighs 397 lbs and requires appropriate unloading equipment, such as a forklift, loading dock or pallet jack on suitable level ground. Terminal pickup is available if needed. Residential deliveries may include an additional fee.
Inspect the shipment before signing. Check the enclosure, receiver, control panel and fittings with the driver present. Record any damage or shortages on the bill of lading and take photographs before accepting the shipment.
Warranty
A 5-Year warranty is available when the compressor receives an authorized start-up. The current listing does not publish the complete warranty terms or commissioning cost, so contact us before ordering and we will confirm both in writing.
Professional commissioning can verify key installation and operating conditions, including rotation direction, oil level and control settings.
If a fault occurs, shut down and isolate the machine before contacting us. Do not open or disassemble the airend before a warranty claim is evaluated. Document the condition with photographs and keep the machine assembled until instructed otherwise.
