The NFKZ3000 filter with chain conveyor is a compact filter, suited for handling large air flows with heavy material content. The filter hopper and the inlet section (optional) separate the medium/large particles and distribute the air to the filter bags. A double chain conveyor in the bottom of the hopper moves the collected material to a rotary valve for out feeding. The filter can be supplied for either continuous operation or with a pause for cleaning of the filter bags every four hours
