• Sound Attenuators – Crosstalk has aerodynamic design to ensure maximum insertion loss and minimal pressure drop. Air-
  gap and length of silencer are selected to meet the required NC level.
• Crosstalk silencer is primarily used to reduce the noise interference between interconnected rooms while maintaining the smooth airflow with acceptable pressure drop level.
• Sturdy construction and high noise absorbing capacity to obtain required insertion loss without compromising performance . Manufactured to ensure long and maintenance free service.
• Splitters are radiused at both ends to minimize self generated noise and pressure loss.
• Casing construction with lock formed seams meet SMACNA standards thus providing excellent strength and rigidity . Thoroughly sealed to prevent air leakage.
• Duct mate flange connection (standard) on both ends in compliance with DW144 standards.
• 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.
• Sound Attenuators – Crosstalk 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”.

ACT Dimensional Details


Options Available Upon Request (Non Standard)

• Flange : M.S angle frame

Product Summary:
Model : ACT
Product Description: Cross Talk Silencer
Installation Guide:

• 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.
• Do not expose the silencer to dirt or excess humidity while installation or during storage.
• The HVAC system should be designed meticulously for proper dehumidification and air- filtration to prevent microbial growth within the silencer and the duct system.
• It is recommended to install the silencer after the volume control damper to prevent regenerated noise.

Product Order Checklist:

• Required room sound criteria.
• Airflow data for each silencer
• Duct size and maximum length available for silencer to fit in.
• Details of the air-handling units with its noise levels.
• CAD drawings with clear details of duct routing from each unit and duct- size till the first air outlet.

• Circular silencer construction provides maximum acoustical performance , while minimizing system pressure drop even at high velocities . Desired aerodynamic performance is achieved by avoiding the need for square to round reducers that will increase the pressure drop.
• Sturdy construction and high noise absorbing capacity to obtain required insertion loss without compromising performance . Manufactured to ensure long and maintenance free service.
• Centre splitter (Pod) are radiused at both ends to minimize self generated noise and pressure loss.
• Full width splitter in the middle and half width side splitters at the circumference .
• Casing construction with lock formed seams meet SMACNA standards thus providing excellent strength and rigidity . Thoroughly sealed to prevent air leakage.
• Slip connection on both ends in compliance with DW144 standards.
• 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.
