Wall Curb Adapter 

The wall curb adapter is installed behind unit and wall. It can be used separately or in conjunction with the adapter extension 

  • When used independently, it facilitates horizontal airflow from the air vents of the unit, with adjustable air directions. 
  • When used with adapter extension, it can direct horizontal airflow to the top of the wall curb adapter through the top air outlet, reduce air supply noises, and ensure more even airflow distribution. 

 


Wall Curb Adapter Extension  


The adapter extension can be used with both the wall curb and the top discharge adapter 

  • When used with a wall curb, it delivers higher horizontal airflow directly above the outdoor unit, reduces air supply noises, and ensures even airflow distribution, as previously mentioned. 
  • When used with the top discharge adapter, it provides high horizontal airflow directly from the top of the outdoor unit, depending on the site application. The adapter extension can be used with both the wall 

curb and the top discharge 

adapter.  



Top Discharge Adaptor

This design allows users to route airflow either vertically or horizontally through air duct depending on site requirements.
