A GI Sound Attenuator is a component used in HVAC systems to reduce the transmission of noise generated by airflow within the ductwork. Galvanized iron is commonly used in HVAC applications due to its durability and suitability for ductwork construction. Its durable construction, effective noise reduction properties, and versatility make it a valuable addition to ductwork systems in a wide range of applications. They come in various sizes and configurations to accommodate different airflow rates, duct sizes, and noise reduction requirements. GI Sound Attenuator is an essential component of HVAC systems, helping to reduce noise levels and create a more comfortable indoor environment.
