MARTIN Electric Vibrators present a complete line of versatile, durable, adjustable, and guaranteed electric vibrators to improve the handling of bulk solids in applications such as: bin activation - screening - compaction - feeding. MARTIN CD36 Electric VibratorsThe most common electric vibrators, CD36 models, provide effective vibration for most bin flow applications. Their 3600-rpm vibratory force is also suitable for the consolidation of low-slump concrete, material compaction, and component testing. Five 115-VAC single-phase models and sixteen 230460-VAC three-phase models are available. Vibrators for use with non-standard voltages or currents are available.For 230 volt, 60 Hz amperage, double the 460 volt amperage.
