Return Air & Security Silencers

Return Air & Security Silencers – Effective, Secure Noise Control Solutions

Our comprehensive line of return air and security silencers is engineered to provide both acoustic performance and enhanced facility security, making them ideal for government buildings, correctional facilities, commercial offices, schools, data centers, and healthcare environments. 

Our product offering includes:

• Return air (RA) silencers
• Crosstalk silencers (for reducing sound transfer between rooms)
• Secure Z-duct silencers (ideal for high-security applications)
• STC-rated silencers (for enhanced sound transmission loss performance)

Each return air silencer is engineered to mitigate unwanted noise traveling through air return pathways without restricting airflow, making them a critical component in any effective HVAC sound control strategy. Our silencers also act as air return sound baffles, providing reliable sound attenuation in systems where airflow noise or speech privacy is a concern.

Whether you're managing noise in a secure facility or controlling cross-room sound transmission in a commercial office, our return air vent silencers and return air baffles are designed for seamless integration into standard ductwork or wall penetrations. By using advanced internal baffle configurations and acoustically absorptive materials, these units function as highly efficient return air sound baffles—achieving maximum noise reduction in minimal space.

Our return air silencer systems are an integral part of any high-performance duct silencing strategy, supporting speech privacy, comfort, and compliance with building acoustic standards.
