|Airgraver Classic with foot control
Here is the Airgraver regulator and my old Gravermax. The power is controlled in the handpiece of the Airgraver, while the Gravermax uses an air pulse from the control box. They both have a connector for a high speed air handpiece, but it is controlled with a foot pedal on the Airgraver and with a knob on the Gravermax control box.
