FIELD: process engineering.
SUBSTANCE: invention relates to air filter for air conditioning system. Air filter (1) comprises disc-shape filtering element (2) with drive assembly (3), preferably, motor connected with filtering element to run the latter. Filtering element (2) is configured to be communicated with vent pipeline (4) so that it is located outside the vent pipeline opening (4a) at the first distance (s) therefrom and concentrically with said vent pipeline. Air cleaned by the air filter is forced into vent pipeline via said opening. Claimed filter comprises also the circular bead (5) located outside the vent pipeline opening (4a) at second distance (k) therefrom and concentrically with vent pipeline. Said bead (4) expands toward the opening (4a). Preferable, said bead (5) is shaped to truncated cone.
EFFECT: efficient cleaning, simple design.
