Self-cleaning filter system
The Nilfisk CFM Infiniclean self-cleaning filter system for industrial vacuum cleaners continuously cleans the filter during unattended, continuous-duty and fine-dust applications. The system is a self-contained, automated filter-purging system that requires no external compressed air supply, secondary power source or operator cleaning. Exhaust air is routed to sequential blast conical filter cartridges, sending built-up dust into the collection container.
