Aldes OCTA D200 + Joint Acoustic Silencer
Acoustics
The Octa silencer with joint effectively attenuates the propagation of acoustic waves (medium frequencies) within a circular duct system with minimal leakage.
Product Code: 11094634
Model: OCTA D200 + joint
The Octa silencer with joint is designed to significantly reduce noise transmission in ventilation and air conditioning networks, ensuring acoustic comfort in tertiary and collective residential buildings. It also provides excellent ductwork sealing. A wide range of diameters is available, from Ø 125 mm to Ø 1000 mm.
Product Highlights:
- High acoustic attenuation performance.
- Energy saving: low pressure drop.
- Energy saving: very low leakage rate (Class D tightness).
Operating Principles:
The interior of the Octa with joint is lined with mineral wool covered by a glass veil to attenuate sound.
Product Description:
The circular Octa silencer with joint is designed to strongly attenuate noise transmitted within ventilation or air conditioning networks, thereby ensuring acoustic comfort in tertiary and collective residential buildings, while also providing very good ductwork tightness. A wide range of diameters covers sizes from Ø 125 mm to Ø 1000 mm.
Application Areas:
- Collective residential housing, New construction, Renovation, Tertiary premises.
