The filter element (3) contains arrays of needle-like articles, and a central part. After entry (A) into the capsule-type structure (2), the air circulates spirally towards a central outflow channel, passing several edge parts and receiving heat from a central part heat transmission medium. It is cleaned as it comes in contact with the needles. Pollutive matter segregated from the air is received in a separate box to the filter element. |
