Automotive engines are equipped with a lubrication system. In addition, they use fuel and air. Long-term engine operation is only possible with clean liquid media. Abrasive particles of internal or external origin contained in moving media lead to more wear and damage to the engine. That is why it is necessary to reduce the size and quantity of these particles. This is the most important function of the filter function.
Motor vehicles can also be equipped with cabin air filters, individual for each air conditioning system. Filtration is a separation process of separating the constant component (liquid or gaseous) from the dispersion component (solid or liquid). Separation is carried out by pressure on the suspension pressed against the porous body.
