BKG® NorCon™ Manual Screen Changer XM

1 screen cavity (100%) in the process

Not possible 

Screen change:
During a screen change, the screen cavity (100%) in the process is removed manually, indexing the other screen cavity (100%) into operation

From the worldwide leader in filtration equipment, Nordson offers the EM and XM manual screen changers. Contamination of the melt stream by metal, wood, paper or internally generated black specks yields products that are unacceptable in appearance and/or performance. Manual screen changers are the least expensive and most suitable option for processes that require infrequent changes. Manual screen changers minimize costly downtime for screen replacement. With a simple swing of the handle lever during routine shutdown, clean screens are quickly brought on-line. No line disconnection occurs, and full production is re-established. As an option, the EMP and XMP models add air assist to the shifting of the 
slide plate.
