A computing system includes a rack system that allows air to flow into the rack system on a first side of the rack system and to discharge from the rack system on a second side of the rack system. One or more air directing devices are coupled to the rack system on the first side of the rack system or the second side of the rack system. At least one of the air directing devices includes a duct having an upwardly increasing interior cross section over at least a portion of the height of the duct. The duct segregates air passing through the duct from air outside the duct. The air directing device may include a louver that couples to the rack system. The louver may include one or more airflow control members that allow air to pass through the louver.
