Aldes OCTA D160 + Joint Acoustic Silencer
Model: 11094633
Product Overview
The Aldes OCTA D160 + joint is a circular acoustic silencer designed to significantly reduce the transmission of sound (particularly in medium frequencies) within circular ventilation networks, while maintaining minimal air leakage.
Key Features:
- High acoustic attenuation performance.
- Energy efficient with low pressure drops.
- Excellent airtightness, classified as Class D according to EN 1751.
- Available for diameters ranging from 125 mm to 1000 mm.
Principle of Operation
The interior of the OCTA silencer is lined with mineral wool covered by a glass fiber veil, which effectively absorbs sound waves.
Product Description
The OCTA circular silencer with a joint is engineered to attenuate noise transmitted through ventilation and air conditioning systems, thereby enhancing acoustic comfort in tertiary and collective residential buildings. It ensures a high level of network airtightness. The product range covers diameters from Ø 125 mm to Ø 1000 mm.
Application Areas
- Collective residential buildings
- New construction and renovation projects
- Tertiary sector premises
Installation
The silencer is designed to be installed directly between two circular ducts in the ventilation network.
Reference Argument
