All-Day Air Power
Spray Foam Magazine – Late Summer 2025 – The Chicago Pneumatic QRS Compressor series is the ultimate workshop compressor: powerful, easy to use and always reliable. Thanks to its rotary screw technology, you get more air while enjoying lower energy costs. Better yet, you can use it all day long without cool-down periods, and you can tailor the QRS to your specifications and preferences. We offer a 3-20 HP range (QRS 3-20M) ideal for spray foam applications. Our QRS units are available in base and tank-mounted models, and we offer a range of options to custom-build your QRS.
The Benefits of Screw Compressor Technology
Stronger Performance: The QRS generates more air and does so more efficiently thanks to its superior compression technology.
Longer Working Hours: While pistons need cool-down periods, the QRS can be used all day long.
Lower Sound Levels: The QRS 3-20M emits just 61 to 71 dB(A). Pistons are typically 20 dB(A) louder.
Cleaner Air: With an oil carry-over of less than 5 ppm, the QRS generates much cleaner air than a typical piston compressor (more than 30 ppm) to protect your pneumatic tools.
