Aldes ACOUSTIQUE - OCTA D250 + joint
Model: 11094635
Product Overview
The Aldes OCTA D250 + joint is a circular sound silencer designed to significantly reduce acoustic propagation (medium frequencies) within a ventilation network while maintaining minimal leakage. It is suitable for tertiary and collective residential buildings, ensuring acoustic comfort and high airtightness.
Product Features
- High acoustic attenuation performance.
- Energy saving due to low pressure drop.
- Energy saving due to very low leakage rate (Class D airtightness).
- Designed for easy installation directly between circular ducts.
- Outer casing made of galvanized steel.
- Internal insulation with mineral wool covered by a glass veil (50mm thickness).
- Fire classification MO (equivalent to A1 according to Euroclasses).
- Product airtightness Class D according to EN 12237.
- Available in a range of diameters from Ø 125 mm to Ø 1000 mm.
