Heidelberg 71.102.1911 Air Filter Atlascop

The Heidelberg 71.102.1911 air filter is the intake filter used on selected Atlas Copco pneumatic compressor setups in Heidelberg offset presses. Official Heidelberg shop and service PDF references identify it as “Air filter Atlascop 1503 0189 00”, while supplier listings also describe it as an air filter for pneumatic compressor service applications. Common number formats found in the market are 71.102.1911, 71.102.1911/, and 711021911; these appear to be formatting variants rather than different functional parts.

Documented compatibility
Official Heidelberg sources and Heidelberg service filter-kit PDFs support compatibility with the following machine families or configurations: CD 102, CX 102, CD 74, XL 75, CS 92, SM 102, SM 74, SM 52, PM 74, and PM 52. A Heidelberg shop snippet also shows Primefire 106, SX 102, and SX 52 in the suitability list. Some aftermarket suppliers additionally list XL 105. Because compressor configuration can vary by press version and serial number, technical verification is recommended for SX, Primefire, and XL 105 applications before purchase.

Technical notes
The industry term most consistently used is air filter or pneumatic compressor air intake filter. Several cross-market sources tie this Heidelberg part to Atlas Copco / Atlascop 1503 0189 00 and to aftermarket references such as C1415 / FC 6658 / Mann SA 6116, though those are aftermarket equivalencies rather than Heidelberg part-number supersessions. Dimension data is not clearly published by Heidelberg in the sources reviewed, but aftermarket listings repeatedly place it in the approximate range of 126–130 mm outer diameter, 85–90 mm inner diameter, and 45–50 mm depth/length, so dimensions should be confirmed against the installed filter before ordering.

Why buy this part
A clean compressor intake filter helps protect the pneumatic system from dust loading, supports stable air supply, and reduces contamination risk in demanding offset printing environments. For maintenance teams and press owners, replacing a worn filter with the correct Heidelberg-compatible spare part supports more reliable compressor performance and cleaner service intervals.
