• The dust collection system comprises of pre-separator and filtration sections. The integrated pre-separator increases the lifetime of filter bags significantly, by collecting the coarse particles and letting only the tiniest particles into the filter bags section.

    SIGMA reverse flow filter with elliptical ARAMID bags is widely dimensioned for efficient operation complying with the environmental standards. The central computer controls the cleaning of filter bags by automatically opening the lateral gates in pre-determined time intervals.

    The recovered dust is collected at the hopper below and a central screw conveyor extracts the dust to be used as recovered filler. Outer surface of the filter as well as the pre-separator section and the collecting hopper are insulated with rock wool for maximum heat efficiency.
