Cross Talk Attenuator

  • Home
  • Cross Talk Attenuator
Model No. : ACT

Specification:
Rectangular Cross Talk Sound Attenuators made of high quality 0.8 mm thick Galvanized Sheet with 100mm thick baffles consisting of 48 Kg/m3 density rockwool. Different specifications can be made to customer requirements based of sound attenuation requirements. Designed in U shape as standard and can be made in Z shape as option.

DESCRIPTION

  • Aerodynamically designed to ensure maximum insertion loss and minimal pressure drop. Air gap and length of silencer are selected to meet the required NC level.
  • Cross talk 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 V shaped at both ends to minimize self generated noise and pressure loss.
  • Duct mate flange or slip 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.
  • Optionally, Nitrile rubber/open cell insulation can be provided of required density and thickness.

PRODUCT ORDER CHECKLIST

INSTALLATION GUIDE

  • Allow at least 2-5 duct diameters in the upstream and downstream for better silencer efficiency.
  • Do not expose the silencer to dirt or excess humidity during installation or 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.
