Foot-mounted rotary electric vibrators generate vibratory force by producing waves of energy from a shaft mounted set of adjustable, unbalanced weights rotating within a cylindrical housing to provide reliable, consistent speed and force output. The heavier the weights, and the faster the weights rotate - the greater the vibratory force output. While all electric rotary vibrators operate at consistently low noise levels, there are multiple models that vary in: Material of construction and electrical hazard classification; size; style; lubrication needs; Speed, amplitude and centrifugal force output based on fixed or variable frequency motor controls; and product finish. AIRMATIC’s product line depth enables us to meet the varied needs of any manufacturing, processing or packaging application, any OEM industry requirement, or any industrial environment demand.
