Exen Air Knocker for Flow Aid System

The Exen Air knocker (Indirect impact type) is a unique piece of equipment in which the force of compressed air causes the piston to energetically strike the base surface, which eliminates the adhesion or clogging of powder. In addition, this knocker is excellent in safety and economics for a flow aid system because it can be used only by air supply, and it can be used safely for powders that has a characteristic to show adhesion when receiving the centrifugal vibration.
