About Chicago Pneumatic
Chicago Pneumatic was founded in 1901 and has been part of the Atlas Copco Group since 1987. The brand is headquartered in Rock Hill, South Carolina, and offers power tools, air compressors, generators, light towers and hydraulic equipment.
CompressorPros offers CP QRS rotary screw and RCP piston compressors. CP piston compressors share pumps and many service parts with BelAire, and CP is an Atlas Copco Group brand, which makes replacement parts easier to source.
Chicago Pneumatic QRS Rotary Screw and RCP Piston Compressors
QRS Rotary Screw Compressors
The QRS range covers 3 to 30 HP. The 3, 5 and 7.5 HP sizes come in 230V single-phase on 60 gallon horizontal tanks, such as the Chicago Pneumatic QRS 5 TM-1 at 16.6 CFM at 150 PSI. Three-phase 230/460V models run up to 30 HP, tank-mount on 132 gallon receivers or base-mount.
Output runs from 8.5 CFM at 150 PSI (3 HP) to 117 CFM at 125 PSI (30 HP), at 61 to 75 dBA. The Chicago Pneumatic QRS 15 BM-3 is a 15 HP base-mount unit rated at 51 CFM at 150 PSI.
The 20 to 30 HP models add wye-delta starting and the ES3000 controller. TMD and BMD versions add an integrated dryer. Compare other rotary screw air compressors with dryers.
RCP Two-Stage Piston Compressors
The RCP two-stage models are 5 and 7.5 HP units on 80 gallon vertical or horizontal tanks, with solid cast iron cylinders. They deliver 18.6 to 25.3 CFM at 100 PSI with a 175 PSI maximum. Premium models add a low oil level switch, automatic tank drain and triple-pass pump-mounted aftercooler.
The RCP-C models use all cast iron pumps at low speed: about 700 RPM on the 5 HP and 900 RPM on the 7.5 HP. The Chicago Pneumatic RCP-C10123H is a 10 HP three-phase Premium unit on a 120 gallon tank, rated at 35 CFM at 100 PSI.
Quiet Performance and Single-Stage Compressors
The QP models put a 5 or 7.5 HP two-stage unit in a sound-insulated enclosure with a 600 CFM cooling blower and high temperature shutdown, rated at 66 to 69 dBA. For lighter use, the Chicago Pneumatic RCP-3561V is a 3.5 HP single-stage unit on a 60 gallon tank, rated at 12.4 CFM at 100 PSI.
Duplex Compressors
CP duplex units run two pumps and motors on one 120 or 200 gallon tank, with a magnetic starter and alternator. You can isolate one side for service and still have air.
Output runs from 36 to 70 CFM at 100 PSI, and the Chicago Pneumatic RCP-C10121D delivers 36 CFM on single-phase power. See more duplex air compressors.
Gas Drive Compressors
CP gas drive units are two-stage compressors on 30 gallon tanks with recoil and electric start. Engines include a 10 HP Briggs Vanguard (16 CFM at 100 PSI), 13 HP Honda and 14 HP Kohler (23 to 25.3 CFM) and a 16 HP Vanguard (35 CFM).
For portable work, the Chicago Pneumatic RCP-508H pairs a 5.5 HP Honda engine with twin 4 gallon tanks for 12 CFM at 90 PSI.
Browse Honda engine air compressors, Kohler engine air compressors, Briggs & Stratton engine air compressors or other service truck air compressors.
Refrigerated and Desiccant Dryers
CompressorPros offers Chicago Pneumatic refrigerated dryers: the CPX non-cycling series from 20 to 184 CFM for rotary screw units or compressors with an aftercooler, and the CPXHT high inlet temperature series from 25 to 125 CFM, which accepts air up to 180 degrees F.
The QRS 7510XL is a 15 CFM point-of-use desiccant system that reaches a -30 degree F dew point.
Choosing a Chicago Pneumatic Compressor
Duty and noise. Two-stage piston compressors are typically rated for 60 to 75 percent duty. If air runs most of the day or the compressor sits near people, a QRS rotary screw unit rated for continuous duty is the better fit.
Air demand. Add up the CFM of the tools you run at the same time, at working pressure, plus a buffer. Compare piston figures (rated at 100 PSI) and QRS figures (rated at 125 or 150 PSI) with that difference in mind.
Power supply. Single-phase shops can choose QRS rotary screw units up to 7.5 HP, RCP piston models and duplex units up to 2 x 7.5 HP. Have a licensed electrician confirm your supply before you order.
Chicago Pneumatic Parts and Maintenance
CompressorPros offers replacement pumps that fit CP machines, including the T39 pump for 5 to 7.5 HP BelAire and Chicago Pneumatic compressors, the C1 and C2 cast iron pumps and the PAT24 and PAT38 single-stage pumps.
For QRS units, parts include Rotair rotary screw lubricant, oil filters, filter kits, MPV and thermostatic valve kits, belts, ES3000 control panels and a replacement airend for some 10 HP units. Piston parts include 30 and 40 weight oil, maintenance and overhaul kits, flywheels, pulleys and starters.
Follow the service intervals in your CP manual.
Chicago Pneumatic FAQs
Who makes Chicago Pneumatic air compressors?
Chicago Pneumatic air compressors are made by Chicago Pneumatic, a brand founded in 1901 and part of the Atlas Copco Group since 1987. Chicago Pneumatic is headquartered in Rock Hill, South Carolina, and also offers power tools, generators and light towers.
What warranty comes with a Chicago Pneumatic compressor?
Chicago Pneumatic lists a 2-year warranty, including valves, on RCP two-stage compressors and 1 year on single-stage units. QRS rotary screw units carry 1 year, extendable to 5 years under CP Secure with an authorized start-up, maintenance per the manual, annual oil analysis and genuine CP parts. Two-stage gas drive Contractor Series units carry 1 year.
Should I choose a Chicago Pneumatic piston or rotary screw compressor?
Choose a Chicago Pneumatic RCP piston unit for intermittent demand and higher pressure, up to 175 PSI. Choose a Chicago Pneumatic QRS rotary screw unit for steady, all-day air and lower noise, since QRS units run at 61 to 75 dBA and are rated for continuous duty. QRS units start at 3 HP on single-phase power.
What size Chicago Pneumatic compressor do I need for an auto shop?
Size a Chicago Pneumatic compressor to the combined CFM of tools running at once, at about 90 PSI, plus a buffer. CP 7.5 HP two-stage units deliver 23 to 27 CFM at 100 PSI, and the 10 HP RCP-C models deliver 35 CFM. Busier shops can move to a CP duplex or a QRS rotary screw unit.
Are Chicago Pneumatic and BelAire compressors the same?
Chicago Pneumatic and BelAire piston compressors share pumps and many service parts, including the T39, C1 and C2 pumps, maintenance kits, pulleys and pressure switches. Model numbers and features differ, so always match the part number to your specific Chicago Pneumatic compressor before ordering.
Can I get parts for my Chicago Pneumatic compressor?
Yes. CompressorPros offers Chicago Pneumatic pumps, Rotair lubricant, piston oils, filters, valve kits, belts, control panels, flywheels, starters and tanks. Match the Chicago Pneumatic part number or model to your machine before ordering, and follow the service intervals in your CP manual.
