An air conveyor conveys bottle containers, the conveyor being constructed as a channel having a general, inverted-U-shaped configuration. The channel has a plurality of air ducts extending through the walls of the channel which communicate with a source of pressurized air to eject streams of air against the bottle containers being conveyed. The streams of air ejected from the ducts impinge upon the bottle containers to push the containers along the conveyor in the direction of travel. Each air duct has a first port opening, which emerges from the sidewall thereof below the pair of flanges, and a second port opening, which emerges from the sidewall thereof above the pair of flanges. The first port opening is a jet port configured to eject a stream of air against the bottle containers, and the second port opening is a vacuum port configured for drawing air from the channel.
