QRS 20HP-30HP Rotary Screw Compressor


The QRS 20-30hp models are rugged rotary screw compressors that combine proven design with superior performance.  Ideal for automotive and industrial applications, the QRS20-30 is engineered and built to support the most demanding requirements. The QRS 20-30 HPD can be supplied base mounted or factory mounted on a 120g receiver with the built in refrigerated air dryer to save vital floor space and provide continuos compressed air delivery.  Installation into every application is quick and easy, simply supply power to the electrical panel, connect your discharge piping and you will have instant access to high quality compressed air.

CPBg 35HP-50HP Gear Drive Rotary Screw Compressor





Experience the innovation and worry-free operation of the Chicago Pneumatic gear drive series of rotary screw air compressors. Pre-filtered air intake and reduced voltage starting mean low operating and maintenance costs. Standard enclosure and ease of maintenance produce an environment that lets you focus on your business, not your compressor!


The high efficiency rotary screw compressor with low power consumption makes the CPC/D the ideal choice for the processes requiring constant or intermittent flow.  Load/no load control with timed shutdown increases the compressor life and improves energy saving operations so the price-performance benefits mean reliable compressed air at minimum cost.
  The CPC/D are managed by the ES4000, an electronic control unit programmed for energy saving operation with intelligent shut down.  The ES4000 control can be programmed to shutdown in accordance with your plant air demand and reduce long periods of unloaded operation, reducing power cost.  The ES4000 control feature can save a customer hundreds or thousands of dollars per year.

CPE/F 75HP-300HP

 The CPE75-150 and the CPF200-300 series rotary screw compressors are base mounted, directly driven units with a microprocessor controller.  Dual prefiltered air intake, precision manufactured components and reduced voltage starting mean security for your application and low operating costs. Standard enclosure and a rapid maintenance design foster an environment that lets you focus on your business, not your compressor!



The Chicago Pneumatic Variable Speed (CPVS) compressor allows you to save operating costs when your application does not require the compressor’s full capacity. Artificial intelligence automatically maintains designated pressure and provides only the air that your system requires. As a result, you save energy and money. The CPVS is great as a stand-alone machine or networked to a base-load CP compressor where it can function as a trim machine.
