Bar Multi-stream Diffuser
The SMARTEMP Bar Multi-Stream Wall Diffuser, type BMW-AD, is a high induction sidewall diffuser. Multi-stream airflow is discharged by a multitude jet elements of differing discharge direction, each manually adjustable to alter the diffuser air pattern, all located behind a linear bar grille.

High levels of draught-free thermal comfort are provided by the multitude of highly inductive individual air streams discharged from its perforated face. It is well suited to high comfort applications such as hotel rooms, apartments, restaurants, aged care and offices.
The advantages of high induction discharge include improved air temperature distribution with low draught-risk, and make the diffuser suitable for both long throws (due to the high momentum of the air stream ) as well as short throws (due to the low air stream velocity).
The SMARTEMP BMW-AD diffuser is suitable for substantially CAV systems (turndown to no less than 50%) including low temperature supply air systems in which supply air temperature is ≥10 ⁰C and ΔTsupply-room ≥ -15 K. Enhanced levels of draught-free comfort are achieved, with air diffusion performance index values (ADPI) typically in excess of 90%.

Product Information
Bar grille face side-blow diffuser with manually adjustable multi-stream discharge pattern for draught-free air supply from walls or bulkheads.
Modular, continuous, flanged and flangeless options available. Mounting frame optional.
 |
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 creating strong supply air dilution with room air and 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, or for combined supply and return air. |
 |
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). |
 |
Slotted face pattern: Linear bar grille with modular or continuous aesthetic. Face aesthetic unaffected by discharge pattern setting. Alternative to perforated face of SMARTEMP Perforated Multi-stream Wall Diffuser (PMW-AD). |
 |
Metal face: Linear bar and frame of aluminium, anodised or powder coated to colour of choice. |
Options
 |
Linear face shape: Continuous linear aesthetic with two flanged or flangeless edge profiles. |
 |
Rectangular face shape: Modular with four flanged or flangeless edge profiles. |
 |
Mounting Frame: Suitable for rendering into plaster board bulkhead or wall. Diffuser clips in from side. |
 |
Plenums: Side-entry connection boxes with concealed diffuser fastenings. |
