Abstract

A találmány szimmetrikus vezetőelemek (24A, 24B) és terelőlapok (26,28) rendszere ventilátor-járókerék (12) által beszívott külsőlevegőszűrővel (32) ellátott ventilátoregység levegőkiömlő nyílásához(19) történő egyenletes szétoszlatását megelőzően megvalósítotttereléséhez és szétterítéséhez. A találmány szerinti kialakítás nemcsupán a turbulenciát mérsékli és a ventillátoros szűrőegységen belülinyomásveszteséget csökkenti minimálisra, de a levegő ürítése során alevegő egyenletes elosztását is fenntartja. A találmány szerintiventilátor egység emellett a magasságát illetően lényegében hasonlóméretekkel valósítható meg, mint a ventilátor-járókerék (12). Ilymódon a jelen találmány minimálisra csökkenti a ventilátorosszűrőegységek zaját még alacsony belmagasságú steril termekben is. Ajelen találmány szerinti vezetőelemek (24A, 24B) és terelőlapok (26,28) a ventilátor-járókereket (12) szimmetrikusan veszik körül, amiugyanazon ventilátoros szűrőegység esetén a felhasználó igénye szerintlehetővé teszi mind az óramutató járásával megegyező, mind pedig azazzal ellentétes irányban forgó ventilátor-járókerék (12)alkalmazását.
