Abstract

Esillä oleva keksintö liittyy partikkelien poistamiseen ilmasta suodatuksen avulla. Tarkemmin sanoen keksintö liittyy aktiiviseen suodatinkerrokseen, joka käsittää detonaationanotimantteja ja suodatinkonsttrukteihin, jotka käsittävät tällaisia kerroksia. Keksintö koskee myös menetelmää suodattimen partikkelien sieppauskapasiteetin parantamiseksi.
