Aspects extend to a baffle for directing air flow in a rack. For example, a baffle can be used to prevent recirculation of air within an equipment rack. When installed in a rack, the baffle creates a tunnel that more efficiently directs cold (or cooler) air from a cold (or cool) aisle into the intake of components that span less than full width of the rack. The baffle reduces excess air from flowing from a cold (or cool) aisle to a hot (or warm) aisle without passing through media and/or cooling a piece of equipment. Preventing excess air from flowing from a cold (or cool) aisle to a hot (or warm) aisle increases cooling efficiency. Use of a baffle can also significantly reduce cold (or cooler) air flowing into hot (or warm) aisle containment and up through the plenum without passing through any media that requires the cooling. Thus, running speed of Air Handling Units (AHUs) can be reduced while maintaining a viable pressure.
