Heidelberg FS.102.3801 Filter Cell / Air Panel Filter

The part number FS.102.3801 is consistently described across supplier sources as a filter cell, panel air filter, or air panel replacement filter for Heidelberg presses. The naming is not fully standardized across sellers, but all sources point to the same product family: a rectangular replacement air filter for Heidelberg offset printing equipment.

For part-number verification, the base reference is FS.102.3801. I also found documented variants FS.102.3801/02 and FS.102.3801/03 in supplier catalogs. Because those suffixes are actively used in the market, they should be mentioned in the listing and checked against the installed filter or machine documentation before purchase.

The technical term most suitable for the industry is filter cell or air panel filter. Several sources describe the part as a pleated filter panel with frame construction for dust and debris capture in Heidelberg press air systems.
