Abstract: A dust separator including a cylindrical housing that is separated by a pair of spaced apart tube sheets into an upper incoming air distributor, an intermediate tube compartment and a lower settling chamber. Large diameter air permeable filter tubes are suspended between the tubes to conduct airborne particles and dust captured inside the tubes into the settling chamber. A dirty air inlet is provided in the distributor while an air outlet connected to a blower is mounted in the lower part of the tube compartment. The blower draws air from the distributor through the tube walls so that the air is cleansed of airborne materials. A perforated control baffle is placed in front of the discharge opening to provide for a uniform and even flow of air through the tubes.
