  Slot Diffuser Type ALS:   


  • The Type ALS Slot Diffuser is available with 1 - 6 slots. The diffuser face is attractively designed with extruded aluminum sections. The ALS can be used in rooms with heights from approximately 2.60m to 4.00m for supply or extract air. Maximum recommended supply air temperature differential is 10K. The slot diffuser provides a stable discharge and can be used for constant or variable volume air flows.

    Airflow rate control is provided by an integral flow straightener and hit and miss damper adjustable from the diffuser face. In the supply mode the discharge can either be set to horizontal or vertical directions by adjustment of the air deflection blades. For stable horizontal discharge a continuous flat ceiling is normally required.
