CMF / CMF-ECO
The CMF / CMF-ECO Continuous Piston Screen Changer enables uninterrupted melt filtration through alternating screen pistons, delivering efficient contaminant removal, stable production, and robust performance for high-temperature plastic processing without shutdowns.
CMF / CMF-ECO
Continuous piston screen changer
Two screen carrier pistons built in heated filter housing are fed by partial melt channels with contaminated melt.
In case of required screen change, one of the two screen carrier pistons is moved out of the housing. The screen can now be changed and then the screen carrier piston is moved back into the housing. During screen change, the entire melt stream is directed through in housing remaining screen.Afterwards, the screen in second piston is changed in the same way. The hydraulics for moving the screen carrier pistons can be operated either manually or automatically.
For CMF-ECO version the retrofit kit for back flush function is not applicable.
