  • Foreign particles slide smoothly down to the bottom of the screen, as the screen's inside surfaces are fine-machined to a smooth finish. Longer cleaning intervals and reduced maintenance costs.
  • Cost-efficient due to Y-pattern body with hydraulically optimised flow path. Higher flow rates and low pressure loss.
  • Range of mesh widths and screen materials available, for versatile applications.
