Gison 4" Air Waterfed Polisher - Safety Lever Type (GPW-7L)
The Industrial Standard for Safe Wet Stone Fabrication
The Gison GPW-7L is a high-performance, water-fed air polisher designed for the rigorous demands of stone, marble, and granite fabrication. Unlike the dial-type models, the GPW-7L features an ergonomic safety lever (dead-man switch) that provides the operator with instant-stop capability, significantly increasing workshop safety.
Equipped with a center water feed, this tool is a critical component for silica dust suppression, keeping your workspace compliant with modern health and safety regulations while ensuring a superior finish on engineered stone and glass.
Why Professionals Choose the GPW-7L:
- Safety First: The lever-type throttle allows for immediate tool deactivation upon release.
- Dust Suppression: Integrated water feed eliminates airborne particles, protecting operator health.
- Heavy-Duty Durability: Aircraft-grade aluminum housing with a high-torque motor for consistent polishing power.
- Ergonomic Comfort: Lightweight design (1.17kg) reduces arm fatigue during extended polishing sessions.
- Side Handle Included: Enhanced tool control for precision edging and surface work.
