Chicago Pneumatic QRS 5.5 150 TM – 5.5 HP Rotary Screw Air Compressor
Quiet Power. Industrial Reliability. Built for Everyday Shop Air Demands.
The Chicago Pneumatic QRS 5.5 150 TM is a true industrial-duty rotary screw air compressor engineered for shops and facilities that need reliable compressed air without the noise, downtime, or maintenance headaches commonly associated with piston compressors.
Delivering 18.1 ACFM at 150 PSI, this 5.5 HP tank-mounted rotary screw compressor combines continuous-duty performance with whisper-quiet operation in a compact footprint ideal for automotive shops, woodworking facilities, fabrication operations, maintenance departments, CNC applications, and general industrial use.
Unlike traditional reciprocating compressors that require cool-down periods, the QRS 5.5 150 TM is designed for 100% duty cycle operation, allowing your team to run air tools, paint equipment, plasma cutters, CNC machinery, and production processes all day long without interruption.
With sound levels around 62 dB(A), this compressor operates quietly enough to be installed directly on the shop floor without needing a separate compressor room. Think industrial air power without the soundtrack of a jackhammer convention. 🔧

Frequently Asked Questions
Is the Chicago Pneumatic QRS 5.5 150 TM suitable for continuous-duty shop use?
Yes. The Chicago Pneumatic QRS 5.5 150 TM is a true rotary screw air compressor designed for 100% duty cycle operation. Unlike piston compressors that require cool-down periods, this unit can operate continuously throughout the workday for automotive shops, woodworking facilities, fabrication shops, and industrial maintenance applications.
How much air does the QRS 5.5 150 TM produce at 150 PSI?
The QRS 5.5 150 TM delivers 18.1 ACFM at 150 PSI. This airflow capacity is ideal for supporting multiple air tools, plasma cutters, paint booths, CNC equipment, and other demanding compressed air applications requiring stable pressure and consistent airflow.
What electrical power is required for the Chicago Pneumatic QRS 5.5 150 TM?
This compressor features tri-voltage 208-230/460V 3-phase electrical compatibility. The flexible voltage configuration allows easier installation in a wide range of commercial and industrial facilities without requiring extensive electrical modifications.
How quiet is the Chicago Pneumatic QRS 5.5 rotary screw compressor?
The QRS 5.5 150 TM operates at approximately 62 dB(A), making it dramatically quieter than most reciprocating air compressors. Its low-noise enclosure allows installation directly on the shop floor without requiring a separate compressor room in many facilities.
What maintenance does the QRS 5.5 150 TM require?
Routine maintenance includes oil changes, replacing the spin-on oil filter and separator element, checking fluid levels, and monitoring service intervals. Rotary screw compressors generally require less day-to-day maintenance and experience less wear than comparable piston compressors.
Can the Chicago Pneumatic QRS 5.5 150 TM be used for woodworking and CNC applications?
Yes. This compressor is an excellent choice for woodworking shops, cabinet makers, and CNC operations because it delivers clean, pulse-free compressed air with continuous-duty capability. The low sound level also makes it ideal for installation directly inside production areas.
What is the difference between the Chicago Pneumatic QRS 5.5 and a piston air compressor?
The QRS 5.5 rotary screw compressor offers quieter operation, continuous-duty performance, lower vibration, cleaner air, and improved efficiency compared to a traditional piston compressor. Rotary screw technology also reduces pressure fluctuations and typically provides longer service life in demanding shop environments.
