Introducing the latest Alpha® Pneumatic Polishing Solution! Alpha® AIR-680UW is a Pneumatic Polisher for use underwater for polishing and grinding.
This tool is a modified version of our best-selling AIR-680 which now has a 27ft vacuum hose to allow underwater polishing on most pool sizes. This high performance, pneumatic polishing tool has a central water-fed distribution system that produces the highest quality finishes. It has a maximum speed of 4,000 RPM, consumes 15 CFM and requires 85 PSI. With a 5/8”-11 spindle, the AIR-680UW is lightweight and ergonomically designed.

Question : I feel the Flex Vacuum Hose is too bulky for the application. Can I use AIR-680UW under the water without Flex Vacuum Hose?
Answer : Yes. However as soon as you stop you polisher underwater, water will try to back wash into the motor so that I highly suggest to use Flexible Vacuum Hose with it. If for any reason, you must use it without Flexible Vacuum Hose, I suggest that you start the polisher in the air then dive with it to complete the task then come back up in the air without stopping the polisher so that air flow is constantly exhausting in one direction that avoid water coming into the polisher.
Question : How much and how often do I need to put rust inhibitor oil in the oil port?
Answer : Alpha® suggests to put only a few drops of rust inhibitor oil in the oil port at the end of the shift then slowly turn on the air to lubricate the rotor and cylinder. If you blow compressed air in full, rust inhibitor oil will come out from the exhaust that would defeat the purpose.
Question : Can I use AIR-680UW for grinding application?
Answer : Yes. You can use either AIR-680UW for grinding applications if you equip it with the right tooling. Since the rpm is set for polishing, I suggest wet grinding to avoid any overheating problems with your tool.
Question : What is the warranty on the AIR-680UW?
Answer : One year warranty (See manual for details)
Question : How can I get the parts list and schematic for the AIR-680UW?

Question : Can I use AIR-680UW as a dry polisher?
Answer : Yes you can. Alpha® will release a new Ecoguard G4 at the end of 2020 so we recommend using this new dust guard designed for 4” dry polishing pads along with a HEPA vacuum to make yourself compliant with the OSHA silica rules.
Question : Does Alpha® offer a pneumatic high-speed angle grinder with center water feed system?
Answer : We offer the PSC-600 which takes any grinding tool with 7/8” arbor depending on your application. Alpha® also offers the PSG-125 and WBCKIT for high-speed applications for cutting, grinding and profiling with an exterior water feed system.
