Machine construction
Outer shell
The outer shell is made of heavy gauge surgical steel and is attached to a heavy
duty, rigid head casting (back gable).
The whole assembly is mounted on a heavy gauge fabricated steel base,
galvanized for long life and corrosion resistance.
Inner cylinder
The inner cylinder is made of perforated surgical stainless steel. It is equipped with
three lifting ribs and has highly-polished side sheets and back with maximum
embossed perforated area to assure high flow of water and supplies through fabrics.
Scientifically correct ratio of cylinder diameter and depth assures maximum washing
action.
The shaft is electrically welded to the reinforced back of the cylinder. A specially
designed chrome-plated sleeve bushing protects the seals from wear.
