Abstract (en)
[origin: EP2264376A1] The invention is an air ventilator (2) which comprises an air inlet (2.1), an air outlet (2.2), and an air channel (2.3) to enable air flow between the air inlet (2.1) and the air outlet (2.2). The air ventilator (2) also comprises a backflow trap (1) for preventing air flowing to a backwards direction in the air channel (2.3). The air ventilator (2) further comprises a first section (2.7) and a second section (2.8). The first section (2.7) having a first height (h1) comprises channelling means (2.9) for controlling the direction of the air flow in the air channel (2.3). The height (h2) of the second section (2.8) is greater that the height (h1) of the first section (2.7). The second section (2.8) comprises a filter (9) for filtering impurities from the air flowing through the air channel (2.3).
