Run this finisher dry or wet, using the included dosing pump to regulate your solution. Polish your glass, ceramic and metal jewelry pieces uniformly and efficiently with easier clean-up. The 8-liter vibratory container is 8 times as abrasion-resistant as steel. Attach the Avalon dosing pump to the top to regulate the addition of solution, while a lower drain hose expels used compound for more efficient polishing. When it's finished, just unfasten the side drain valve to release the container's contents. Hold a separating screen under the valve to filter out the media, leaving you with your finished product. This is a 220 volt unit with an external 110 volt transformer.
