Spiro-SAFE silencer diameter 560 mm - length 600 mm (100 mm insulation)

Spiro-SAFE Sound Attenuator Diameter 560 mm - Length 600 mm (100 mm Insulation)

The Spiro-SAFE sound attenuator diameter 560 mm - length 600 mm (100 mm insulation) is a round ventilation silencer made from 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 occupied spaces and technical rooms remain within acceptable limits.
The connection of the attenuator features male spigot ends on both sides with integrated double EPDM lip seals, providing an airtight and reliable connection to round ventilation ducts.

Practical Information

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

The outer casing is manufactured 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 shell that withstands mechanical stress during installation and operation. The product code clearly indicates the type of attenuator, insulation thickness, duct diameter (Ød1), and length, making 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 One?

Compared to the standard attenuator, the premium sound attenuator offers several advantages that make it better suited for certain applications:

1. Wool Thickness: The premium attenuator uses 100 mm thick mineral wool cut from rolls, allowing the insulation to better fit the inner shape of the attenuator and providing more uniform sound attenuation.
2. Central Core: Starting from diameter 315, the premium attenuators feature a central core. This core directs the airflow through a perforated inner tube, increasing the contact of sound waves with the absorption layer. This results in more effective attenuation of mid and high frequencies.
3. More Uniform Noise Reduction: The combination of flexible insulation, tight connection, and thoughtful construction ensures that the premium variant delivers more consistent noise reduction across a broad frequency range. The standard variant’s noise reduction may be somewhat less uniform, especially at lower frequencies.
