Spiro-SAFE premium silencer diameter 160 mm - length 600 mm (100 mm insulation)

Spiro-SAFE premium sound attenuator diameter 160 mm - length 600 mm (100 mm insulation)

The Spiro-SAFE premium sound attenuator diameter 160 mm - length 600 mm (100 mm insulation) is a cylindrical ventilation sound attenuator made of galvanized steel, specifically designed for use in ventilation and air handling ducts. This attenuator is engineered to effectively reduce noise generated by airflow and mechanical fans, ensuring that sound levels in living spaces and technical rooms remain within acceptable limits. \nBoth ends of the attenuator feature a male connection (insertion end) with an integrated double EPDM lip seal, providing an airtight and reliable connection to circular ventilation ducts.

Practical information

Sound absorption is achieved through glass wool located between the inner and outer casing of the attenuator. Depending on the version, the wool thickness is 50 mm or 100 mm for the PREMIUM-100 model. The mineral wool is flexible and cut from roll material, allowing it to conform well to the shape of the attenuator and ensuring uniform sound reduction along the entire length of the product. This guarantees consistent attenuation, even with variable airflow rates and smaller duct sizes.

The outer casing is made from high-quality galvanized steel to ensure durability and reliability, resulting in a robust and corrosion-resistant finish.

The construction is sturdy and functional, with a solid outer casing capable of withstanding mechanical stress during installation and use. The product code clearly indicates the type of attenuator, insulation thickness, duct diameter (Ød1), and the attenuator length. This makes it easy to select the correct attenuator for any ventilation project, from residential buildings to complex commercial installations.

Why is the premium variant better than the standard version?

The premium sound attenuator offers several advantages over the standard version, making it better suited for certain applications:

1. Wool thickness: The premium sound attenuator uses 100 mm thick mineral wool cut from rolls. This allows the insulation to better conform to the inner shape of the attenuator, resulting in a more uniform sound attenuation.
2. Central core: From diameter 315 onwards, the premium attenuators are equipped with a central core. This core ensures that air flows through a perforated inner tube, increasing the contact between sound waves and the absorption layer. This design particularly improves attenuation of mid and high frequencies.
3. More uniform sound reduction: The combination of flexible insulation, precise sealing, and thoughtful construction ensures that the premium variant provides more consistent sound attenuation over a wide frequency range. In contrast, the standard version may offer slightly less uniform attenuation, especially at lower frequencies.
