Since the QRS is quiet by design and creates such little noise, which reduces employee fatigue, the QRS can be installed almost anywhere. With a low sound enclosure and innovative cooling fan, the QRS compressor offers the lowest noise levels available, allowing you to install it virtually anywhere in your shop. You can actually talk on the telephone or have a conversation standing next to the QRS while it is compressing air.

Chicago Pneumatic's patented asymmetric rotary screw design with oil injection during the compression stage for lubrication, sealing and cooling, the QRS offers enhanced long term durability and reduced maintenance costs resulting in lower cost long term operation with no wearing parts. With a Chicago Pneumatic rotary screw compressor, there are no piston rings, valves, rod inserts, bushings and pistons as there are with piston pump compressors. There are also no valves, valve plates or valve strips to service or maintain. The extended service intervals of a QRS Series rotary screw compressor save time and money. Convenient service panels allow easy access to all internal components for servicing. QRS compressors are simple to service by design, and you or your employees can perform all of the regular maintenance required in your facility saving you money. If preferred, annual maintenance contracts and extended warranties are available for customers who want the assurance that their QRS compressor is always operating at peak performance and serviced by trained technicians only.
