About This Product
4,000 RPM Pneumatic Polishers for Wet Stone Fabrication
The Alpha® AIR-830 and AIR-834 Pneumatic Polishers are high-performance, center water-feed tools for wet polishing, drilling, and profiling hard surfaces. Both models operate at a maximum no-load speed of 4,000 RPM and use a lightweight, ergonomic body to improve maneuverability during stone fabrication work.
5-Vane Motor and Central Water-Feed System
A newly developed motor uses a five hybrid composite vane design to increase power and service life compared with the previous generation. The central water-feed system supplies water directly through the tool regardless of working position, while the redesigned end case improves access to the air and water controls and reduces the risk of breakage.
Splash Control and Improved Tool Handling
A redesigned splash guard helps block water while maintaining visibility of the working surface. The gear head is protected by a silicone cover that adds cushioning and insulates the operator's hand, while the enhanced spindle shaft and included full-size wrench simplify accessory removal.
All-Weather Air and Water Hoses
Standard AIR-830 and AIR-834 configurations include 15 ft. air and water hoses designed to remain flexible from -40°F to 140°F (-40°C to 60°C), along with a reversible side handle, splash guard, exhaust hose, rust inhibitor oil, water quick coupler with shut-off valve, and additional maintenance accessories. Machine-only AIR-830M and AIR-834M configurations include the polisher and rust inhibitor oil without the standard accessory package.
