COSMOS Sound Attenuator's were developed to various requirements from the consulting engineers, owners & contractors. They provide the most economical choice for solving the wide range of noise control issues encountered in the HVAC field. The COSMOS range of rectangular attenuators provides optimized acoustic performance for application where high levels of noise reduction are required. These attenuators are suitable for most applications incorporating sound attenuation and airflow. For example; HVAC air distribution systemThe control of fan noise and cross talk attenuation are typical HVAC applications for these attenuators. The standard construction is ideal for this type of applications. Industrial MachineryHeavy duty constructions are available for industrial applications incorporating thick wall mild casings, heavy duty flanges and supports.Acoustic Splitter OnlyThe splitter elements can be supplied separately for applications such as concrete or builders work air risers.
