Models are also available for Class II, Div. 1, Group F and G environments. High-deflection (HD) models have all the advantages of an electromagnetic design with the added benefit of high amplitude. HD models operate at a fixed rate of 1,800 vibrations per minute at approximately 0.1875-in. amplitude, similar to a mechanical screener.
