- Aerodynamic design to ensure maximum insertion loss and minimal pressure drop. Air- ngap and length of silencer are selected to meet the required NC level. n
- Cross talk silencer is primarily used to reduce the noise interference between interconnected rooms while maintaining the smooth airflow with acceptable pressure drop level. n
- Sturdy construction and high noise absorbing capacity to obtain required insertion loss without compromising performance . Manufactured to ensure long and maintenance free service. n
- Splitters are radiused at both ends to minimize self generated noise and pressure loss. n
- Casing construction with lock formed seams meet SMACNA standards thus providing excellent strength and rigidity . Thoroughly sealed to prevent air leakage. n
- Duct mate flange connection (standard) on both ends in compliance with DW144 standards. n
- Acoustic infill media is of superior quality non combustible & have fungi resistant characteristics meeting the requirements of EN ISO 1182 and ASTM C665 respectively. It has excellent noise reduction coefficient characteristics with an additional qualification of being biologically inert. n
- Tested and certified by Intertek USA (NVLAP accredited laboratories) in accordance with ASTM standard E477-06a ,entitled “standard method of testing duct line material and prefabricated silencers for acoustical and airflow performance”. n

- Do not place the silencer immediately after the noise source like air handler or blower in order to allow uniform flow profile to develop. Leave at least 2-5 duct diameters in the upstream and downstream of the silencer for better silencer efficiency. n
- Do not expose the silencer to dirt or excess humidity while installation or during storage. n
- The HVAC system should be designed meticulously for proper dehumidification and air- filtration to prevent microbial growth within the silencer and the duct system. n
- It is recommended to install the silencer after the volume control damper to prevent regenerated noise. n
