Air filter inner liner element is intended for holding filtering material. Also this element is intended for vehicle intake air flow to the combustion engine control and cleaning. The aim of this invention is to increase the efficiency of the air filtration by air flow control. The aim of this invention can be obtained when air filter inner liner element is a hollow cylinder shape with different diameters at the ends. This hollow cylinder surface area consists of at least four coils, which are twisted in opposite directions over the entire inner liner surface area, and of at least four longitudinal stiffeners. The air filter inner liner consists of equal or different ring diameters at the ends (1), which are connected with at least four coils rotated by 90 degrees (2) (where two of them have the direction of rotation from the left to the right, the other two from right to left), which are respectively coupled to at least four longitudinal stiffeners (3) rotated by 90 degrees in parallel position of the inner liner rotational axis. |
