Original GRS AirTact Control System (004-935)

It allows the handpiece to be controlled by methods other than a traditional foot pedal, including palm, thumb, finger, or even mouth-operated control elements. This provides greater flexibility, improved ergonomics, and enhanced precision for engraving, stone setting, and other fine handcraft applications.

What Does AirTact Do?

AirTact expands the control capabilities of compatible GRS pneumatic engraving systems. The system can be used with Palm Touch, Thumb Touch, and FootPod control elements, allowing the handpiece to be operated by hand or foot depending on the application and user preference.

AirTact functions as a standalone control unit that connects to an existing GRS pneumatic system. It processes control signals pneumatically, without the need for electrical sensors or moving parts within the handpiece itself.

Traditionally, GraverMax and GraverMate systems are operated using a foot pedal. With AirTact, users can:

• Control the handpiece with the palm of the hand
• Control the handpiece with the thumb or finger
• Use hand and foot controls simultaneously
• Achieve extremely sensitive power control without foot movement
• Reduce fatigue during extended engraving and stone setting sessions

AirTact is particularly popular among engravers and stone setters who require maximum control, consistent hand positioning, and improved ergonomics when working under magnification.
