Outlet Assembly Having a Plurality of Operating Modes for Improving Air Flow in an Air Distribution System

An outlet assembly having a plurality of different operating modes for improving air flow in an air distribution system is provided. The assembly includes a first blocking element supported by a first wall of a housing for movement between blocking and unblocking positions within a cavity of the housing. The first blocking element prevents a first layer of air from flowing immediately adjacent the first wall in its blocking position. A second blocking element is supported by a second wall of the housing for movement between blocking and unblocking positions within the cavity. The second blocking element prevents a second layer of air from flowing immediately adjacent the second wall in its blocking position. An actuator subassembly including a selector member is supported for movement between a plurality of predefined positions which correspond to first and second blocking modes and a nominal unblocking mode.
