Chicago Pneumatic QRS Rotary Screw Air Compressor

Discover the Chicago Pneumatic QRS Rotary Screw Air Compressor

The Chicago Pneumatic QRS Series is a fixed-speed, oil-injected rotary screw lineup built for continuous duty in service and light industrial environments—ideal for tire shops, paint shops, car dealers, and maintenance departments. QRS units deliver reliable air in a small footprint with low noise, so you can install them close to the point of use without wrecking your work environment. Choose base or receiver-mounted configurations, with or without an integrated refrigerant dryer, to create a compact, all-in-one setup that’s easy to live with and easier to maintain.

Service is straightforward and cost-effective. The screw element has no wearing parts, and common items are spin-on for quick changes. Vibration-isolated assemblies, UL/CSA-approved controls, and robust cooling ensure the QRS is built to last.

For smarter uptime, select models feature the ES4000 Connect controller and ICONS remote monitoring. You get leak detection, better start/stop logic, tracked running/working hours, and proactive service warnings—plus remote visibility of pressure, temperature, hours, and mode from your computer or phone. That reduces unplanned downtime and cuts total cost of ownership.

To keep moisture under control in intermittent duty, QRS offers condensate-prevention options such as an oil heater, tropical thermostat, line filters, low-loss timer drains, and an integrated dryer with receiver tanks where needed.

• Power & voltages: 3HP, 5HP, 7.5HP, 10HP, 15HP, 20HP, 25HP and 30HP. Single-phase 230V on 3hp, 5hp, 7.5 hp; three-phase 208–230/460V and 575V on 10 - 30 hp.
• Pressure ranges: 125–150 psig standard (model dependent); 100 and 175 psig available via kit.
• Air delivery: roughly 12.6 cfm (QRS 3 @ 116 psi) up to 60.8 cfm (QRS 20 @ 125 psi).
• Noise level: as low as 61 dB(A) (approx. 61–71 dB(A) across the range).
• Receivers: 60-gal ASME/CRN (3–10M) and 120-gal ASME/CRN (10–20M).
• Operating modes: Start/Stop (QRS 3–7.5); Load/No-Load (QRS 10–20M).

Compared with a piston setup, expect stronger performance, truly continuous operation, lower sound, and cleaner air—with <5 ppm oil carryover versus the higher figures typical of pistons—protecting tools, dryers, and downstream equipment.

Performance is stated per ISO 1217, Annex C and sound per ISO 2151. For peace of mind, QRS is backed by a 5-year warranty (with authorized startup). Add Platinum Care to extend full parts & labor coverage an additional 24 months on top of the major-component plan.
