Nordson Corp.'s BKG FlexDisc filter for piston-activated screen changers substantially enlarges the available area of filtration, without the need to increase machine size, according to the company. That means processors and recyclers achieve finer filtration, higher throughputs, longer filter service life and reduced specific backflush volume.
Nordson recommends the BKG FlexDisc for bottle-to-bottle PET recycling, PET fiber recycling and battery separator film applications.
The function of hydraulic pistons, with which many BKG screen changers are equipped, is to insert screen cavities into the melt stream for filtration and remove them for cleaning or replacement.
Nordson is based in Westlake, Ohio.
