• AIR-830: ~4,000 RPM for controlled polishing and detailing
• AIR-850: ~5,500 RPM for faster material removal and finishing work
• Central water-feed system: Delivers consistent water flow during operation to reduce dust, cool pads, and improve surface finish quality
• Lightweight ergonomic build: At about 2.75 lbs, designed for reduced fatigue during long polishing sessions
• High air-efficiency requirement: Runs at ~15 CFM @ 85 PSI, making it a true professional compressor-driven tool
• Jobsite durability focus: Built for continuous use in stone shops and on-site fabrication work
• Improved operator control: Features splash guard, ergonomic grip, and enhanced spindle design for smoother handling and visibility
• Best for: Stone fabricators, countertop installers, and contractors needing precision wet polishing on granite, quartz, marble, and engineered stone
• Key consideration: Requires a high-capacity air compressor and proper water supply setup—this is not an electric tool

Q&A

Maintenance Tips

• Lubricate air inlet daily: Add pneumatic oil before/after use to prevent internal wear
• Flush water system after every job: Prevent slurry buildup and clogging in feed lines
• Clean spindle and pad interface: Ensures smooth pad rotation and prevents vibration
• Inspect hoses regularly: Check air/water lines for cracks, leaks, or blockage
• Keep exhaust ports clear: Prevent overheating and maintain motor efficiency
• Replace worn seals/O-rings: Maintains stable air pressure and water control
• Dry tool before storage: Prevent internal corrosion in air motor components
• Check RPM performance: Irregular speed may indicate air supply or vane wear issues
