The Bard 7051-083BX front linear supply air diffuser (boxed) is an OEM air distribution component used at the unit discharge to help direct supply airflow evenly into the conditioned space. With a 42 x 10 size, this diffuser is selected to match specific Bard wall-mounted and packaged unit supply openings, supporting proper throw and minimizing hot and cold spots when the correct factory part is used. If your existing diffuser is damaged or bent, replacing it with the genuine Bard 7051-083BX helps restore intended airflow patterns, reduce rattles from misfit aftermarket grilles, and maintain the unit’s designed air delivery. Confirm dimensions and unit model compatibility before ordering to ensure correct fit.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
