- Last Chance Filter (LCF)



The Acro Last Chance Filter (LCF) is a self-contained filter assembly for point-of-use filtration in digital printing systems. It is designed to be used together with any of Pall's larger capsules in large systems or as a stand-alone filter in smaller systems. A laboratory-size filter is also available for testing new ink formulations and conducting printing trials.

HDC II and Rigimesh media options are available for the Acro LCF. HDC II media is all polypropylene and has a tapered pore structure. It provides good flow rates, long service life, and excellent gel retention. Rigimesh media is a sintered woven stainless steel wire mesh structure that provides excellent chemical compatibility across a wide range of ink chemistries.
