Abstract: A damperless, controlled speed, coverless, isometric air conveyor and method for conveying lightweight containers en masse or individually at a controlled speed includes a first set of louvers extending through a conveyor surface from a common plenum at an incline to a conveying surface so that the air passing through the louvers has a downstream force vector of a first magnitude. A second set of louvers extend through the conveyor surface from the common plenum at an incline to the conveyor surface so that the air passing through the louvers has an upstream force vector of a second magnitude which is less than the first magnitude thereby creating a vector force differential in the downstream direction at any given location under the bottom of each container to cause movement of the containers in the downstream direction.
