Acoustic flexible connections (or acoustic expansion joints) are manufactured using a unique combination of materials to control airstream breakout noise. These connectors are designed for both vibration isolation and noise attenuation.
Depending on the application, the flexible inner wall is manufactured from high-temperature PTFE or rugged EPDM; acoustic media is then sandwiched between this inner wall and a tough outer acoustic barrier. Finally, everything is secured in place with two sets of heavy duty backing bars.
All of our acoustic flexible connections are acoustically rated with predictable and guaranteed noise attenuation levels. Depending on the fan noise spectrum, attenuation can be as high as 30 dBA.
For easy installation, our acoustic flexible connections are provided with pre-drilled flanges custom cut to match any existing connections. These flanges are backed with weld nuts and fitted with proprietary shipping braces that hold the unit to its proper length during installation.
