This unit features a full digital design, with reduced circuit complexity and improved reliability. The new air-pressure guide system offers digital display of actual air-pressure along with a LED system that guides the operator to the optimal air pressure for the mode being used. Additionally, you can adjust the Post-Flow time with a quick turn of the dial to suit different duty and job requirements.
