Product overview
Structural simplification of the module body and gun head reduces overall size and weight. A cylinder pressure regulating method is used to make tightening down-pressure adjustment more convenient and reliable. The design removes the external spring to reduce wear-part maintenance and offers front or back installation to suit various field layouts.

Product advantages

• Cylinder pressure adjustment for reliable and repeatable downforce regulation.
• Optimized structure for stable screw suction-pipe support and compatibility with optional functions for complex conditions.
• Front or rear installation possible to match integration constraints.
• Vacuum module equipped with a large-capacity vacuum filter to extend maintenance intervals and provide stable vacuum levels.
• Reduced module and nozzle size for lower weight; external spring eliminated to reduce wear-part upkeep.
• Lightweight 12 Nm series adapted for collaborative robots; overall torque coverage extended up to 200 Nm.
• Maximum screw cap diameter expanded to 27 mm; interference-avoidance stroke extended to 300 mm.
