The air filter is used to remove dust and sand particles from the air entering the cylinder to purify the air and reduce engine wear. Maintaining the air filter plays a key role in extending the service life of the engine.

At this stage, dry air filters are widely used in forklift engines. Under normal circumstances, a first-level air filter can be installed. In harsh working environment, it is necessary to series a one-stage dry air filter or oil bath air filter for secondary filtration. The secondary filtration of the air filter can effectively improve the working efficiency of the engine and ensure its stability.

Dry air filter

Dry air filter is a filter in which the air entering the filter passes directly through the paper filter element to separate the dust particles. Filter filter material for filter core, nonwoven fabric.

Oil bath type air filter

Oil bath type air filter, the shell contains a certain amount of oil. When the engine is working, the air flows into the cover shell at a high speed, due to inertia, the larger dust particles are thrown to the oil surface and adsorbed, the lighter dust particles are adhered to the filter screen when passing through the filter element, and the filtered air flows into the carburetor through the center tube to complete the filter work.

When using a forklift truck, it is necessary to carefully maintain the air filter according to the actual operating conditions of the forklift truck to improve the service life of the forklift engine.
