Designed specifically for underwater polishing and grinding applications, this professional-grade pneumatic polisher allows pool service companies, plaster specialists, and pool renovation contractors to perform repairs and surface restoration without draining the pool.

Built from Alpha's proven AIR-680 platform, the AIR-680UW features an extended underwater vacuum hose system that helps protect the tool during submerged operation while delivering the consistent power and control professionals demand. Alpha specifically designed the system for underwater polishing applications in swimming pools and water features.

Why Pool Professionals Choose the AIR-680UW

Draining a pool can be expensive, time-consuming, and inconvenient for homeowners. The AIR-680UW allows contractors to complete many polishing and restoration tasks while the pool remains filled, reducing downtime and improving profitability.

Pool professionals frequently highlight three major benefits:

• Reduced project downtime

• Ability to perform underwater repairs

• Professional-quality finish on plaster and pool surfaces

Designed Specifically for Underwater Operation

Unlike conventional polishers, the AIR-680UW incorporates a specialized vacuum hose system designed to help prevent water intrusion during submerged operation. Alpha recommends using the vacuum hose while working underwater to maximize tool protection and performance.

The system includes:

• 27-foot underwater vacuum hose

• 15-foot flexible air and water supply hoses

• 30-foot air hose

• Central water-fed distribution system

• Lightweight ergonomic design

• 5/8"-11 spindle compatibility

These features allow contractors to work comfortably throughout most residential pool environments.
