ABSTRACT:
An air conveying apparatus includes a housing that defines an inlet through which material, air and other gases enter the housing, a first compartment that communicates with the inlet, a second compartment, a plenum, a material outlet, and an air outlet. Partitions separate the plenum from the first and second compartments and the first compartment from the second compartment. A fan places the plenum and the first and second compartments under negative pressure, drawing air, gases and materials into the housing through the inlet and into the first compartment where the heavier particles drop to the bottom of the housing and out of the material outlet. The fan then draws air and other gas into the second chamber, through at least one filter assembly, and into the plenum through an opening in a partition. An air blast assembly forces material trapped by the filter assembly to drop to the outlet.
