Rectangular Sound Attenuators

Overview

Sound attenuators are a proven and effective method for reducing the noise generated by fans and other equipment. Also referred to as duct silencers, sound traps or mufflers, they are designed to reduce the noise transmitted from a source to the receiver.

Rectangular silencers are designed to reduce noise in rectangular ductwork while minimizing system pressure drop. The simple design, relatively low cost, and high level of performance flexibility make rectangular silencers a reliable and cost-effective choice.

For HVAC applications, they are commonly installed on intake and discharge sides of a fan or air handling unit. They can also be used on the receiver side of noise generating equipment (terminal boxes, air valves and dampers) and in areas outside the primary air system where they can reduce transfer noise between spaces

Typical Applications

Rectangular silencers are intended for silencing noise in Rectangular ductwork and a wide range of design options allow them to be integrated into any HVAC system with ease.
