ABSTRACT:
A plenum chamber for an air slide conveyer is provided with two air chambers one within the other. The inner chamber communicates with a medial strip of the membrane which separates the chambers from the rest of the duct through which the material passes when fluidized by air from the plenum chamber. The central air duct also serves to support the membrane which is drawn over it and then clamped between the two halves of the duct. The supply of air to either the outer or inner chamber may be separately shut off. The lower half may be removed as a unit for repair or replacement of the membrane. A novel seal is provided for preventing the edges of the membrane from becoming wet and acting as a wick to moisten and clog the central portions of the membrane.
