STJH-RECTANGULAR-ELBOW-SILENCER-90D-DISSIPATIVE

Rectangular Elbow Silencer 90-Degree Dissipative

Noise attenuation and a right-angle direction change in one duct component.

The combined bend and attenuator uses a constrained duct corner.
Shaped splitter noses guide the flow into the turn.

Introduction de produit

Curved acoustic splitters guide air around the bend. Glass-fibre fill behind perforated metal dissipates acoustic energy, allowing the elbow to provide sound treatment where there is insufficient room for a separate straight silencer.

Key Features

The combined bend and attenuator uses a constrained duct corner.
Shaped splitter noses guide the flow into the turn.

Paramètres techniques

Applications

Fan-room duct corners
Supply bends with limited straight length

Solutions for Your Application

There is no straight run available for an attenuator.

The sound-absorbing section is incorporated into the required elbow.

An abrupt empty corner creates an unfavorable flow path.

Curved splitters guide the air through the direction change.
