The Vibrasonic Spiroscreen® (patent pending) enables powder coatings to be sieved on finer meshes with more accuracy than ever before. This increases the value of the screened powders as well as improves their final quality. The unit achieves these improvements by eliminating mesh blinding. Eliminating blinding offers other benefits, including an increase in production output. Sieving capacities increase because all the apertures remain clear and powder can pass through them. Downtime is reduced, as there is no need to stop the production process to clean the mesh.
