Benifits of this kind of screen changer

1, Double-piston screen changer works simultaneously. One net works. Another replaced; Without interrupting the flow of material and production. And eventually fulfills the exchange of screen without stopping the machine.
2, Exhaust system device can fully defuse the gas mixed in the materials, then improving product quality. And double channels expand the filtration area to meet more productive, more high-quality production need s from customers.
