A twin-loop dust collector comprises: a case with an opening on the upper side thereof, being provided on a lateral side thereof with a vent hole; a net plate provided to cover the opening, one side of the net plate is pivotally connected with the case to allow lifting of the net plate. When the net plate covers the opening, the net plate is transversely mounted to divide the vent hole into two areas; thereby when in air suction, two loops for exhausting air are formed above and below the net plate respectively.
