An optional Auto-Air package for use on column and CAGT amplifiers reportedly saves energy. The system senses pressure build-up while an air tool is being used and switches airflow from minimal "cost-savings" mode back to normal. The regulated air pressure stays on for a predetermined time after the tool is removed from the part or master gage.
