The main body of the screen changer
Hydraulic unit
Electrical controlling pack
Characteristics of GM-DP-R series continuous screen changer/melt filter
Two round removable breaker plates on each bearing piston
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Fit for almost all kinds of polymers
It works well under the high pressure 400bar(40Mpa) not impact the high performance.
The filtration screen area covers from 56cm² to 520cm², depending on the size, fit for output range from 30kg/h to 1800kg/h.
