"A Way to nextgen filtration technology..."

Platen type screen changer

The hydraulic screen changers appeal to a traditional but demanding audience. Designed for high production or recycling extrusion lines, due to ongoing technical development, have reached a high degree of ergonomics. The high reliability and durability testify to the quality of this product, which meets the diverse needs, with excellent results even in the most difficult and challenging situations. Available with filtering areas from Ø 80 to Ø 300 mm. units are equipped with a new protection system which allows better access to the sliding plate during screen replacement, and a new wiring system that allows rapid intervention in case of maintenance.

The JSB PLATENT TYPE Hydraulic Screen Changer allows for filtration of most polymers with minimum disruption during a screen change. JSB Hydraulic Screen Changers feature a pressure activated seal that not only seals to 500 bar, it eliminates degradation and gels caused in other slide plate type screen changers. JSB Hydraulic Screen Changers are designed to withstand extreme temperatures and filter highly sensitive compounds.
