The Connectdec type Akudec is a strong, flexible and corrugated aluminium inner duct with a aluminium laminate outer jacket. The space between the inner and outer ducts is filled with 25 mm sound absorbing material. A non-woven barrier between the inner duct and the glass wool prevents the diffusion of glass wool particles.
The attenuator is by standard on both sides equipped with galvanized metal sleeves for direct mounting to the rigid duct work or equipment.
