Aldes OCTA D900 + joint Acoustic Silencer

Acoustics and Sound Insulation

The OCTA D900 + joint silencer is designed to significantly reduce acoustic propagation, particularly in medium frequencies, within circular ventilation networks while maintaining a low leakage rate.

Product Highlights:

• High acoustic attenuation performance.
• Energy efficient with low pressure drop.
• Energy efficient with a 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 effectively absorb sound.

Product Description

The circular OCTA silencer with joints effectively reduces noise transmitted through ventilation systems, ensuring acoustic comfort in tertiary and collective buildings. It also provides excellent network 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 premises

Installation

The silencer is designed to be inserted directly between two circular ducts of the network.
