This internal air filter, designated CF400 and produced by Mann-Filter, captures airborne particulate before it enters the engine intake system. It sits inside the primary air cleaner housing on the host tractor or telescopic loader. A clogged filter element restricts airflow, causing a drop in engine power and increased fuel consumption. The filter element uses the manufacturer's specified media density and pleat geometry to match the original assembly's airflow resistance and dust-holding capacity. On installation, ensure the sealing surfaces are clean and the housing is latched fully to prevent unfiltered air from bypassing the element.
