– The DEC International AKUDEC-2 Ø250mm (1m) circular semi-flexible sound attenuator is a high-performance acoustic duct silencer designed to reduce noise and vibration in HVAC, ventilation, and air conditioning systems.
– Built for both durability and flexibility, it features a corrugated aluminum inner duct with an aluminum/polyester laminated outer jacket, ensuring strong mechanical resistance and easy installation.
– The inner and outer ducts are separated by a 25mm layer of sound-absorbing glass wool, providing outstanding acoustic insulation while maintaining airflow efficiency.
– A non-woven fabric barrier between the layers prevents the diffusion of glass wool particles, ensuring clean, safe air delivery.
– Both ends of the AKUDEC-2 attenuator are equipped with galvanized steel sleeves for fast and secure connection to rigid ductwork or HVAC units.
– Perfect for industrial, commercial, and residential HVAC installations, the AKUDEC-2 Ø250mm delivers quiet performance, energy efficiency, and superior airflow, making it a top choice for professional ventilation systems.
– Made in Netherlands.
