Aldes OCTA à baffle D560 (11094996)
Acoustique et Isolation
Product Overview
The OCTA acoustic baffle with D560 diameter is designed to significantly reduce the propagation of acoustic noise, particularly in the medium and high-frequency ranges, within circular ventilation networks.
Key Features:
- High-performance acoustic attenuation.
- Energy efficiency due to low pressure drops.
- Energy efficiency due to low leakage rate (Class C tightness).
The OCTA baffle is lined with mineral wool and a glass veil to attenuate sound. A central baffle made of rock wool further enhances its sound-absorbing capacity.
This circular acoustic silencer effectively reduces noise transmitted through ventilation networks, ensuring acoustic comfort in tertiary and collective buildings. It also provides excellent network tightness. The product range covers diameters from Ø 250 mm to Ø 630 mm.
Application Areas:
- Collective residential housing
- New construction and renovation
- Tertiary sector buildings
Installation and Implementation
The OCTA baffle is installed directly between two circular ducts in the ventilation network.
