Abalandeli be-axial abanama-blade e-aluminium fan, afakwe onogada abaqinile be-epoxy coated kuma-mounts anti-vibration.Amamotho afakwe idivayisi yokuphepha eshisayo eyakhelwe kuma-windings, exhunywe kumatheminali ahlukene ebhokisini letheminali.Ngakho-ke le divayisi yokuphepha ingahlanganiswa kumjikelezo wokulawula.Ukulawulwa kukagesi kufanele kuhlelwe ngokungcono ngesisetshenziswa sokusetha kabusha ngesandla ukuze kuvinjwe ukushintshwa okuqhubekayo kokuvula/ukuvala (ukukhubeka) kwamamotho.
