Acro® Last Chance Filters

High Performance Point-of-Use Filters Ensure Printhead Protection from Contamination and Optimum Printer Performance

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.

Features

  • Economical and compact point-of-use filter for digital printers
  • Specially selected connections for fast filter changes
  • Available in three sizes, for a wide range of applications
  • Housing material optimized for maximum blockage of UV light
  • Media selected for maximum performance in ink jet systems
  • Designed to be used together with another Pall capsule or as a stand-alone filter
 
Features Advantages Value
Manufactured using Pall's Premium Syringe Filter technology (Acro 25 LCF) Large effective filter area in a compact design Can handle a wide range of flow rates without printhead starvation
UV-light-resistant housing materials (Acro 25 LCF, Acro 37 LCF) Negligible UV light penetration into the filter assembly (<0.02%) Helps prevent curing of UV-sensitive materials
Low internal ink hold-up volume Minimal ink required for flow Rapid ink system priming cycles
Economical construction Minor impact on initial build and maintenance costs Performance improvement
with minimal impact on cost
All versions feature all–polypropylene construction Good compatibility across a wide range of ink jet ink chemistries One filter design can be applied universally across multiple printer families
Luer-Lok1 compatible and compression fitting connectors on both inlet and outlet Secure inlet and outlet connections with positive sealing architecture Minimal chance for leakage; fast filter changes
No binders, glues, or mold release agents used Low extractables Good chemical compatibility; economical disposal
