Industrial ABP-2081100 Air Filter Element

ABP-2081100 is a 5-micron cartridge air filter element engineered for Sanborn/ Coleman Ingersoll Rand 51-A21 oil-bath compressors, serving as the intake air filter that traps dust and particulates before they enter the compression chamber of a two-stage unit. You’ll commonly see it cataloged as SANBORN ABP-2081100, RA5A80, or IR5A80V1D, with explicit compatibility to the 51-A21 family and related 80V-series models used in industrial and workshop environments. The 5-micron rating indicates the particle size it can stop, contributing to reduced wear and longer service life for critical components, while replacement is done using this exact part when servicing the unit’s air intake. References in catalogs link ABP-2081100 to RA5A80V1D and IR5A80V1D configurations and to DV Systems equipment, confirming its role as a replacement element for machines sharing the 51-A21 80V platform.
