The Alpha WDP-120, a wet/dry variable-speed surface polisher, is designed for all decorative concrete applications, including edge polishing. The included Ecoguard attachment minimizes the amount of water splashed, and the in-line GFCI will provide safety and protection. A vacuum cleaner can also be attached to the Ecoguard for dry concrete floor polishing without creating dust. By removing the Ecoguard’s front cover and attaching the magnetic plate, contractors can polish right up to the wall.
The Alpha AIR-300 is designed for unique applications that are difficult to accomplish using conventional polishers. A smaller version of the well-known Alpha AIR-658, the AIR-300 is ergonomically designed to fit comfortably in your hand and only weighs 1.6 pounds. The smaller design is easy to maneuver and produces flawless sink rims and bowls. The Alpha AIR-300 accepts 3-inch and 4-inch discs along with 2-inch and 3-inch rubber pads.
Finally, Alpha Ecogrinder Caddies allow operators to work standing, not on their knees, when grinding and sanding concrete, terrazzo and masonry products or doing surface preparation work. The height adjustment mechanism allows the caddy to be adjusted to accommodate individual users. The unit is available in two versions for both Ecogrinders Alpha offers. A halogen light shines above the grinding area to show scratches in dark areas.
