Champion ADCP100 Filter Silencer Adapter

Champion ADCP100 Filter Silencer Adapter is a 1-inch intake filter adapter designed to mount onto Champion air compressors, serving as a filter/silencer assembly for the compressor’s intake. The part is listed as ADCP100 and is associated with Champion R-series pumps, with product references tying it to models such as R10C and R15A, while other catalogs and listings reference compatibility with R15 and R30 as well. Market variants appear in configurations described as a 1" push-fit adapter and a version with 1" FNPT threads; one listing notes an outside diameter of about 1.5 inches and includes a silicone O-ring for sealing. This adapter is used to connect an intake filter element to the compressor, providing filtration for incoming air and contributing to intake noise reduction in the path to the pump. It is listed as a replacement for 5Z664 or ADCP100 in some retailer catalogs, reflecting its role as a direct or aftermarket substitute within Champion’s intake filtration ecosystem.
