Product Description

Dual pistons continuous screen changer

Benefits of this   continuous  screen changer 
Increased production
Reduced downtime & scrap
Leak-free operation
Increased filtration area
Reduced inlet pressures
Accurate, repeatable screen changes
Reduced maintenance

This kind of continuous screen changer now is widely used on the PET monofilament extrusion machine, and it makes a good efficient, the filament will not be interrupted when change the screen ,and greatly reduces the waste of the raw material and the intensity of labor.
