SMARTEMP Perforated Multi-stream Diffuser

Perforated face side-blow diffuser with manually adjustable multi-stream discharge pattern for draught-free air supply from walls or bulkheads.

Location – side: Air supply from sidewall, bulkhead or side of duct.
Mixed flow discharge: High aspiration of individual air streams 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 ≥ -12 K.
VAV dependent throw: VAV turndown to approximately 50% @ ∆Tsupply-room ≈ -12 K, with throw dependent upon airflow rate.
Adjustable direction: Multi-stream jets are individually adjustable, providing air pattern direction, spread and throw adjustment for up/down, left/right, short, medium or long throw.
Manual adjustment: Manual air pattern adjustment through diffuser face by means of an Allen key avoids inadvertent changes to discharge pattern setting (eg by cleaners).
Rectangular face shape: Flanged edge profiles. Height from 134 to 251 mm. Standard width options: 612, 950 and 1490 mm. Bespoke widths: 207 to 1490 mm.
Perforated face pattern: Discharge through perforated metal face with 60° stagger. Face aesthetic unaffected by discharge pattern setting. Alternative to bar grille face of SMARTEMP Bar Multi-stream Wall Diffuser (BMW-AD).
Metal face: Perforated metal finish in extruded aluminium frame, painted to colour of choice.

Plenums: Side-entry connection boxes with concealed diffuser fastenings.

Product Information

Features

  • Highly inductive multi-stream discharge for draught-free comfort.
  • Multi-stream discharge direction manually adjustable via Allen key through diffuser face.
  • Allen key adjustment prevents inadvertent discharge direction adjustment (eg by cleaners).
  • Black plastic discharge elements (ABS, V0 fire rated) located behind the perforated discharge face break the airflow into a multitude of highly inductive individual air streams of differing discharge direction.
  • Adjustable air streams have four different discharge angles, with the outer angles flatter than inner ones, and each may be rotated to one of six discharge directions, ensuring highly inductive, broad dispersion of the supply air flow for draught-free air supply.
  • Perforated discharge face and frame of metal, painted to colour of choice.
