DFAC Filter Capsules for Digital Printing Systems

Among these features is an opaque exterior shell to protect against UV-light intrusion, large-bore connections to minimize pressure loss, and a wide range of industry-accepted media appropriate for most digital printing applications.

Two capsule sizes are available, with twice and four times the capacity of the popular Multiple Application Capsule (MAC).

Filter media offerings include Profile® Star media and HDC® II media in six grades, with ratings from 3 μm to 20 μm.

Features

• Compact assembly with high flow capacity filter
  The DFAC filter capsule features both a compact assembly and a pleated filter with high flow capability. This is a critical combination in high-flow recirculating ink systems, where consistent flow rates are required for accurate jetting.
• Opaque capsule
  The black polypropylene exterior housing protects against UV light and prevents ink from curing inside the filter. This capsule is also suitable for ink chemistries that are not UV curable.
• Key media options for digital printing
  Profile Star and HDC II filter media are available. Profile Star media is an industry standard, with excellent gel-retention capability and long life. HDC II media has a pleated, high-area design with excellent flow rates.
• Easy change large-bore connections
  Large-bore inlet and outlet connections are present in both size capsules to minimize pressure loss. The standard connections are Swagelok*-compatible compression fittings, with available 6 mm and 8 mm connections.
• Venting capability
  The heavy-duty, compression-fitting vents allow for venting at start-up (recommended) or periodic venting as needed, or serve as connections for continuous venting, if required.
• All-polymeric construction
  The all-polypropylene construction of the filter capsule makes it suitable for use with most ink jet ink formulations.
