Abstract

Keksinnön kohteena on pulssisuodatin (100; 110), jossa on kaksi suodatusvaihetta (101, 102; 113, 114), joilla on keskenään erilaiset suodatusominaisuudet. Ensimmäinen suodatusvaihe (101; 113), jonka kautta puhdistettava fluidivirta kulkee ensimmäiseksi, on järjestetty suodattamaan karkeammat materiaalit ja toinen suodatusvaihe (102; 114) on järjestetty suodattamaan hienojakoisemman aineksen fluidivirrasta. Ensimmäinen (101; 113) ja toinen suodatusvaihe (102; 114) on muodostettu erillisinä laskostettuina rakenteina, jotka ovat valinnaisesti ilmaraon (103; 115) muodostavan välin päässä toisistaan.
