The Heidelberg F2.028.422S is a sheet separation blower used in the feeder separation system of selected Heidelberg sheetfed presses. In Heidelberg documentation, the technical name appears as “Sheet separation blower” and, in multilingual feeder parts catalogs, as “Lockerungsbläser / Sheet separation blower / Souffleur-séparateur de feuilles / Soplador-separador de pliegos.”
Confirmed part number
- Base part number: F2.028.422S
- Sellable / shop variant found in primary source: F2.028.422S/01
Part number variations found
The reliable variation I found is F2.028.422S/01, which appears in Heidelberg’s eShop and in multiple aftermarket listings. I did not find authoritative evidence of a different engineering revision with changed dimensions or material; the main difference documented online is the commercial SKU formatting with the /01 suffix.
Correct industry term
The best technical term for this listing is:
Sheet separation blower
Related terminology used in the market includes blower foot for separation, which appears on patent/equivalent aftermarket listings, but the official Heidelberg naming is sheet separation blower.
Documented compatible Heidelberg models
Primary Heidelberg eShop data shows this part suitable for:
- CD 102 / CX 102
- SM 102 / SX 102
- XL 105 / XL 106
- CS 92
- Primefire 106
Heidelberg feeder catalog pages also place F2.028.422S within feeder assemblies for CD 102 / CX 102, SM 102, and XL 105 product lines. That supports the fitment above and confirms feeder-system use, but machine version and feeder configuration should still be checked before purchase.

- Part type: Sheet separation blower
