Acoustic Duct Elbow turns a ventilation route while treating noise carried from the fan. Incorporating acoustic lining into the bend uses a section already needed for routing, useful when there is too little straight duct length for a separate attenuator.

FEATURES AND BENEFITS

How it helps

Lined change of direction

Sound reaches the absorbent lining through its protective face as air travels around the elbow.

Custom bend geometry

Cross-section, radius and leg lengths can be coordinated with adjacent plant and building obstructions.

APPLICATIONS

Where it is used

Plant-room connections

Treat fan noise at the turn leading away from equipment toward occupied areas.

Restricted service voids

Combine a bend and acoustic treatment where the available route cannot fit two separate components.

SELECTION GUIDANCE

Choosing the configuration

Acoustic duty

Select the lining and internal passage for the noise frequencies, airflow and pressure-loss allowance of the route.
