Aldes OCTA D710 + joint Acoustic Silencer
Model: 11094647
Acoustics
The Octa silencer with joint effectively reduces the propagation of acoustic noise, particularly in medium frequencies, within circular duct systems while maintaining a low leakage rate.
Product Highlights:
- High acoustic attenuation performance.
- Energy efficient with low pressure drop.
- Energy efficient with very low leakage rate (Class D tightness).
Operating Principles:
The interior of the Octa silencer is lined with mineral wool and a glass veil to attenuate sound.
Product Description:
The circular Octa silencer with joint is designed to significantly reduce noise transmitted through ventilation networks, ensuring acoustic comfort in tertiary and collective buildings. It also provides excellent system tightness. A wide range of diameters is available, from Ø 125 mm to Ø 1000 mm.
Application Areas:
- Collective residential housing.
- New construction and renovation projects.
- Tertiary sector premises.
Installation:
- Installs directly between two circular ducts in the system.
Reference Features:
- Outer casing made of plain galvanized steel or aluminum.
- Inner casing made of perforated galvanized steel or aluminum.
- Jointed connection collars for diameters from Ø 125 to Ø 630 mm. Standard connection collars for larger sizes.
- Acoustic insulation: rock wool + glass veil.
- Fire classification: MO.
Key Characteristics:
- Outer casing: plain galvanized steel.
- Inner casing: perforated galvanized steel.
