Air terminal units provide localized or zone control of air distribution in buildings by regulating the air volume and may be equipped with supplemental heating and cooling systems. Our innovative and performance-based noise and vibration control strategies effectively attenuate radiated noise, inlet noise, outlet in-duct noise, break-out noise, and structure-borne noise from these systems in an open ceiling or drop ceiling plenum space. We also provide aesthetically appealing and ASTM E84 Class A fire rating solutions. Using a holistic approach and engineered equipment-specific solutions, we manufacture sound and vibration products for air terminal systems to meet your unique specification requirements, increasing their effectiveness and your peace of mind.
