Chicago Pneumatic QRS 20 Base Mounted With Dryer Screw Compressor

Oil-injected Screw Compressors

The QRS 20-30 is a rugged, rotary screw compressor that combines stealth with superior performance. Ideal for automotive and light industrial applications, the QRS is engineered and built to support the most demanding requirements.

QRS compressors run at a lower RPM's. This means it can run indefinitely, non-stop, 24 hours a day. Super quiet because the helical screws don't actually touch one another. A huge benefit of rotary screw compressors is that they can be mounted close to work spaces without requiring hearing protection.

The QRS 20-30M is managed by the ES4000 basic controller, an electronic control unit programmed for energy saving operation with intelligent shutdown. The ES4000 controller makes operation very simple with warning and service alarms
