The Telsonic sieving resonators were developed for use in sieving machines. The resonator distributes the ultrasonic vibrations optimally over the entire screen fabric. The continuous cleaning of the fabric improves sieving performance, minimises material stress and prevents powder caking on the fabric and other components.

The resonators are available with fixed or bolted-on converters and are certified for explosive zones. In order to ensure uninterrupted powder flow, the converter can also be mounted outside of the sieving machine.
