Product Description

Dual bolts continuous screen changer for film blowing machine

This GM-DP-R series  continuous screen changer/ melt filter is consist of
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.
