The GRS® #921 Monarch Quick-Change Airtact Handpiece works with your pneumatic engraving system to provide precise control of the airflow with pressure from your palm on the handpiece instead of a foot pedal. The sensitivity of the handpiece can be adjusted to your preferences. The Airtact Control System is required and sold separately.
Requires a compatible GRS engraving system with oil-free compressed air; compatible GRS systems include:
• the GraverMach AT (118306) OR
• the Airtact Control System (118650) connected to a GraverMax G8 (118307), GraverMach, GraverMax SC, GraverSmith (118304), or Classic GraverMax (the G8 and GraverSmith cannot be operated without the Airtact Control system)
