Tank breathing filters | TLF I 1-25 … 8-250; TLF II 1-25 … 6-80; TLF III 1-25 … 7-125 5/14 Function, section The tank breathing filter guarantees air exchange in the fluid tank. Depending on the machine cycles, air can be pulled into the tank with contamination when a breather filter is not used. A tank breather filter will accomplish both the pressure equalization and air filtration preventing contamination from entering the tank through the air exchange. It basically consists of a threaded cover (1), a filter element (2) and a bottom housing (3) to accommodate the filter element. The...
