Abstract
An air seeder is provided with a pneumatic distribution system for delivering product through a plurality of primary tubes arranged in first and second rows. The pneumatic distribution system has a plenum housing having a plurality of outlet ports also arranged in first and second rows, each of said plurality of outlet ports associated with one of the primary tubes. A fan is in fluid communication with the upstream end of the plenum housing. A damper is mounted in the plenum housing upstream from the outlet ports for directing the air flow toward at least one of the first and second rows of primary tubes, and a perforated baffle plate is mounted in the housing between the damper and the outlet ports. The baffle plate has a plurality of openings adapted for governing the airflow into the outlet ports.
