PURPOSE: A dust collector using monolithic filter cloth combined with filter clothes of cylindrical type and rectangular type is provided, which is designed to flow air in the same direction of dust from top to bottom, so that any re-entrainment of dust is decreased, dedusting of bags using high pressure air in downward direction is easily performed thus diminishing required the number of bags and capacity of fan can be reduced saving power consumption. CONSTITUTION: The system comprises a housing(101), a suction pipe(102), a supporter for filter bags(103), a baffle(104), cylindrical filter bags(105), a rotary valve, a rectangular filter bag, a discharge pipe(108) and a fan(109). Dust laden air with the flow direction changed by baffle(104) come down from the top of the housing, flow into the cylindrical filter bags(105) leaving dust on the outer surface and finally exhausted by the fan(109). The rectangular filter bag collects dust laden in the clean air preliminarily filtered.
