• Sleeve Partition

Bard part number 120-351 is an OEM sleeve partition used inside the wall mount air conditioner sleeve to separate internal sections so airflow, pressure, and service clearances stay as designed. A correct partition helps prevent air bypass and recirculation in the sleeve area, supporting proper ventilation and heat pump or cooling performance on compatible Bard wall mount and sleeve-based configurations. Use this replacement when the original partition is bent, missing, or damaged from prior service so the unit can be reassembled to factory layout and operate reliably with the correct internal separation.
