摘要
<p>The suction device has an air filter (15) which separates a raw air duct (12) and pure air duct (13). The raw air duct is connected with a source of raw air and the pure air duct is connected with a low-pressure source. The air filter has two filter zones (16,17) which have different flow resistances. The two filter zones are arranged in a common casing (11).</p>
