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.
Circular silencers provide a practical, engineered solution for controlling duct noise in systems with round ductwork. The round shape eliminates the need for costly transitions and the associated turbulence and system pressure drop. With high quality, leak-free construction and many optional features, the RCA silencer is suitable for most applications.
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
Circular silencers are intended for silencing noise in circular ductwork and a wide range of design options allow them to be integrated into any HVAC system with ease.
