Sound Attenuator

A sound attenuator is a noise-reducing device used in HVAC systems to minimize sound transmission through ductwork while maintaining efficient airflow.

A sound attenuator, also known as a duct silencer, is designed to reduce noise generated by fans, blowers, and air movement in HVAC (Heating, Ventilation, and Air Conditioning) systems. It consists of an insulated casing with sound-absorbing materials that dampen unwanted noise without disrupting airflow. These are commonly used in commercial buildings, hospitals, data centers, and industrial setups to ensure a quieter indoor environment. Sound attenuators come in various shapes, including rectangular and circular, to suit different duct configurations. Their installation helps improve acoustic comfort, enhances energy efficiency, and ensures compliance with noise control regulations.

Key Features:

  • High-performance noise absorption

  • Customizable lengths and diameters

  • Fire-retardant acoustic insulation

  • Minimal pressure drop

  • Compatible with round and rectangular ducts
