Product Introduction

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.

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.

Available Options

Welded casing
Flanged connections
Access door
