DuctSox Silencer is a sound attenuator for fabric ductwork systems that quiets operational and airflow noise from AHUs and VAV boxes. Sound in the 500-2,000 Hz range is dampened by 28-35 dB with a 4-inch-thick wall of rock wool, making it ideal for offices, libraries, classrooms, and other sound-sensitive areas.
Available in diameters of 12-36 inches in 2-inch increments. An optional center bullet version is designed for larger mechanical equipment.
