It uses enhanced cellulose media to filter particles down to 3 microns, protecting fuel injectors and pumps from wear. This filter is typically installed on Mack trucks such as the CH, CHN, Granite, and Vision series equipped with ASET or AC engines. Regular replacement is part of fuel system maintenance to avoid power loss, rough running, and injection system damage.
