ABSTRACT:
In a dust separator arrangement including a battery of filter chambers, the cavity of each filter chamber is divided into an upper compartment and a lower compartment by a layer of filter medium. A tubular member has an upper orifice in the upper compartment and extends downwardly through the layer of filter medium to a lower orifice in an attached valve chamber. Two valve seats on the valve chamber define openings of the valve chamber permanently communicating with a raw gas manifold and a purging gas manifold respectively, while a purified gas manifold permanently communicates with the lower compartment, the manifolds being common to the several filter chambers. A single valve member mounted in each valve chamber may be moved between respective positions of sealing engagement with the two valve seats by an actuator.
