The vibrators PULSAR 2, PULSAR 4, PULSAR 6 and PULSAR LARGE, respectively for 2, 4, 6 and 18 large rings, have been carefully designed to facilitate any kind of investment or stone. Due to the new electronic control system, the vibration is perfectly vertical and the vibration intensity may be set from the lowest intensity, almost imperceptible, up to a maximum intensity value, much stronger than would be required for even by the most difficult casting. Features: • Continuous vibration, perfectly vertical, and continuous vibration control. • Illuminated switch. • Rubber table removable for cleaning.
