Double piston continuous screen changer

Double piston continuous screen changer is used to optimize filtration in a continuous process. Different types of double piston continuous screen changers, their benefits, and application limits are as follows.

Double piston continuous screen changers benefits:
Simple operation and uncomplicated changing
High operational reliability
Short material residence time
Low pressure consumption
Flow channel geometry without any spots

Double piston continuous screen changer models:
Standard double-piston screen changer: after retrofitting, it is now possible to maximize the filtration area on any existing continuous screen changer, by a factor of up to 2.5x.
Standard double-piston screen changer
Extrusion screen changer with start-up valve
Continuous operation with integrated start-up assistance
Screen changer with enlarged filter area
Continuous operation with enlarged filter area
Continuous screen changer for extrusion and compounding
Single-piston screen changer with continuous operation has been specifically developed for the extrusion industry and includes curved breaker plates (patent pending), bringing up to 4 times more filtration surface, with 75% of the active piston surface now acting as filtration area.
