Self-cleaning dust filtration unit functional components comprise: housing, rainproof inlet cover with bird-proof netting,electric damper, autonomous sand filtration module, sand discharge fan and motor, supply fan and motor, outlet, electrical control cabinet, etc.

Self-cleaning dust filtration units constitute a consumables-free filtration and ventilation system. In arid regions such as northwestern China, conventional mechanical ventilation coupled with physical filters frequently suffers from filter clogging, compromising stable airflow delivery. The prolonged replacement of physical filters incurs substantial costs. Self-cleaning dust filtration units effectively resolve these issues by automatically removing various contaminants including sand, dust and particulates. Designed for perpetual operation, they require no replacement parts and eliminate the need for manual maintenance.
