Product Information

Multi-jet linear slot diffuser with manual, thermal or electric discharge direction adjustment for cooling/heating of high spaces.

Features:

  • High induction alternating multi-jet discharge
  • 1-way or 2-way blow
  • Individual jets rotatable through 90°
  • Discharge direction adjustment options:
    • Manual (standard)
    • Thermal actuator (with bias adjustment)
    • Electric actuator (2-position or modulating)
Location – above: Integrated flush with a closed ceiling or freely suspended.
Mixed flow discharge: 2-way blow or 1-way blow high aspiration alternating multi-stream discharge intensely mixes supply air with room air, producing high induction and creating strong supply air dilution with rapid discharge velocity decay. Low velocity, high momentum supply air motion of substantially uniform temperature distribution over short or long throws is achieved. Ideal for enhanced thermal comfort (ADPI ≥ 90%).
Return air: Suitable for use as a return air inlet.
Low temperature supply: May be used for low temperature (cold air) supply systems (Tsupply ≤ 10 °C), where ∆Tsupply-room ≥ -16 K.
VAV dependent throw: VAV throw dependent upon airflow rate. Minimum airflow dependent upon ∆Tsupply-room (eg turndown to 25% and ≈1 L/s/m2 @ ∆Tsupply-room ≈ -16 K).
Adjustable direction: Air pattern adjustable through 90°, from horizontal (cooling) through diagonal to vertical (heating).Maximum recommended discharge height:

  • Cooling: ≈20 m
  • Heating: ≈10 m
Manual adjustment: Default airflow direction adjustment is manual.
Slotted face pattern: Barrel nozzles create linear slot appearance with 1 to 6-slot options.
Plastic Face: Adjustable black (default) or white (optional) plastic barrel nozzles.
Metal Face: Anodised or powder coated linear aluminium profiles.
