SELECTING THE ELECTRIC VIBRATOR - italvibras

• rotational: the vibrating force is directed in all directions through 360° in a rotational way, either clockwise or anticlockwise. • unidirectional: the vibrating force is directed in one single direction in fade-free sinoidal reciprocating mode. The "rotational" method is obtained by using a single electric vibrator.
