Complete Air Filter for Stratus Rocking Piston Compressors Beneficial Bacteria (Koi Ponds & Water Gardens) EasyPro concentrated pond dyes mayThis is the complete air filter used with Stratus Rocking Piston Compressors. There was a switch over in 2013, so be sure that yours is this style rather than the former ERPA. The complete filter includes 1 each ERPF12E air filter element.
