FAN WITH DUST GUARD Russian patent published in 2004 - IPC

Abstract RU 2229036 C1

FIELD: ventilators and fans. SUBSTANCE: proposed fan with dust guard includes housing with channel, rotation drive unit installed inside housing, great number of blades located in channel and connected with rotating shaft of rotation drive unit for rotation, and dust guard installed on inlet hole of channel to close inlet hole. Dust guard is completely coupled with blades for rotation together with blades. As insects or large size particles of dust cannot get into housing with air flow created at rotation of blades, connection of structural members is strong. Owing to the fact that eccentricity is brought to minimum, structural members are saved from damage and generation of noise is limited. EFFECT: improved reliability of fan. 12 cl, 15 dwg
