Heidelberg Wet Air Filter 00.580.0741

The most reliable product name for 00.580.0741 is Heidelberg Wet Air Filter. Two catalog-style references describe it specifically as “Wet air filter (B)” and place it in the air supply category. Marketplace and supplier listings use broader names such as filter, air filter, air pump filter element, and metal filter, but for a technical catalog the clearest industry term is wet air filter.

The exact part number confirmed is 00.580.0741. I also found the suffix-style variant 00.580.0741/ listed by a specialist parts seller, but I did not find evidence that this trailing-slash format represents a different functional version. It appears to be a catalog formatting variant rather than a distinct replacement part, so the safest wording is to mention it as a listing variation only.

For compatibility, the strongest sources are more conservative than many marketplace listings. A Heidelberg service-parts style catalog and a PDF distributor copy both associate 00.580.0741 with SO, MO, Printmaster GTO, and Speedmaster SM 74 for air supply use. Some aftermarket sellers broaden that to GTO 46, GTO 52, MO, KORD, SB, and Windmill platens, but those claims are less authoritative and should not be treated as confirmed across all versions without checking the machine parts book.
