How to switch air pressure?

How to switch pressure on your mobile air compressor?

“Simply switch pressure – the compressor will do the rest.” Each application has its own needs, with different combinations of pressure and flow. Different applications used to mean different compressors. Not anymore. With Chicago Pneumatic's dual pressure compressors, only one compressor is needed to power different applications. This range features our toughest mid-size compressors to date, designed to ease your work and enjoy the benefits of two machines in one package. The dual pressure range works at flows between 5.5-7.0 m³/min and 9.8-11.5 m³/min. Depending on the application you are working on, you can either switch working pressure at between 7-10 bar or 12-14 bar, depending on the model chosen. How does it work? It's just a matter of changing pressure by a simple push on the button. Switching between different applications never was this easy.
