Chicago Pneumatic QRS 25 125 BM 25 HP Quiet Rotary Screw Air Compressor, 99.4 CFM @ 125 PSI

The QRS 25 125 is a rugged, rotary screw compressor that combines proven design with superior performance. Ideal for automotive and industrial applications, the QRS is engineered and built to support the most demanding requirements. The base mount model can save vital floor space and provide a continuous supply of quality compressed air. Installation into every application is quick and easy - simply supply power to the electrical panel, connect your discharge piping and you’ll have instant access to high quality compressed air. This specific QRS 25 is a base mount model and can be paired with a separate receiver tank. The QRS25 compressor is designed for 100% continuous duty and can support the most demanding air requirements. This means it can run indefinitely, non-stop, 24 hours a day.

The motor is a tri-voltage totally enclosed fan cooled (TEFC) motor. This makes for extremely simple installations with any building that has three phase power. The compressor is pre-shipped 230/3/60hz power, but can be easily changed over to 460v or 208v three phase. Since the motor is totally enclosed, this results in less debris being pulled into the bearings and windings for a longer life.

Maintenance is simple on the QRS line. The oil filter and separator elements are spin-on filters for easy removal and installation. The air filter can be replaced in just a few seconds. Since this model includes a dust protection enclosure, the inside of the compressor stays clean to increase life and performance. The dust enclosure doubles as a sound a sound attenuation device which lowers the decibel level to 69dBA, making this one of the quietest compressors on the market. An integrated air cooled aftercooler combined with a cooler operation results in less moisture buildup and less moisture downstream in your production equipment.

AirCare is also included with this QRS compressor. With AirCare, compressor control and monitoring are always within reach. The app keeps a constant eye on your compressor and sends you real-time notifications. You can also remotely control the unit to turn it on/ off or improve its efficiency. The app can even run a leakage detection program. Download AirCare now from your app store. Installing AirCare is as quick and easy as using it!

The QRS 25 is managed by the ES4000 microprocessor 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. This microprocessor controller features icon based display with pressure and temperature readings for easy monitoring. It also displays running hours, unload hours, and keeps track of maintenance requirements. Automatic restart after voltage failure is also included as standard.
