This top of the line 110v, powerful (320 watts) machine measures 12.5" x 8.2" X 9" overall with a blue/white vinyl-clad finish and a 9.4" x 5.4" x 4" stainless tank of 3.4 qt. capacity. Controls include automatic cavitation tuning, cycle timer, and a pilot light. The tank has a convenient drain plug, a stainless cover, and can hold several dismantled regulators or valves at one time. Pans and baskets must be purchased separately. Additional Info: Perhaps the most effective way to clean small parts including those from scuba regulators / valves is by ultrasonics. This requires a special machine which generates high-frequency vibrations (beyond the range of human hearing) within certain liquid solvents. Forceful bubble impulsions bombard virtually every surface of any material submerged in the liquid; this cavitation literally blasts the contaminants off the parts, producing a state of microscopic cleanliness! It silently removes grime, rust, oil, dyes and grease from metals, ceramics, glass, plastics, rubber and synthetic fibers. However, ultrasonics can be harmful to some composite materials and a few elastomers, so manufacturers' manuals should always be consulted with regard to compatibility. Because this process cleans so thoroughly, it's an approved method for oxygen cleaning. Another virtue of ultrasonic cleaning is that the vibrations can be passed at undiminished strength from one liquid to another. Thus, if water is placed in the tank of the machine, the cleaning activity will be transmitted to any solvent contained in an auxiliary pan or vessel placed into the water. If one has extra pans of selected solvents, a single machine can utilize a variety of cleaning agents by merely exchanging pans! All Global cleaners can employ this reciprocating pan system and we recommend it when acidic solvents must be used. (Each machine includes detailed instructions on ultrasonic cleaning).
