Dust laden air is drawn into the dust collector through the inlet due to the suction created by the exhaust fan and passes through filter cartridge elements. The abrasive resistant inlet promotes dropping cut high particulate, generates uniform air flow, thus, it increases the filter life. The dust gets deposited on the outer surface of the cartridges and clean air flows through the center passage of cartridge into clean air plenum. Clean air further exits into the atmosphere through the outlet duct. Cartridge are periodically and automatically gets cleaned through air purging. Sequence circuit activates solenoid valves for highpressure air purging of preselected cartridges. Dust released from cartridges slides downward into the hopper for further collection into the dust bin.
