Spiro-SAFE Silencer Diameter 180 mm - Length 600 mm (100 mm Insulation)

The Spiro-SAFE silencer with a diameter of 180 mm and a length of 600 mm (100 mm insulation) is a round silencer duct component made from galvanised steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce sound transmission through air ducts. The silencer is designed to effectively attenuate noise from fans and airflow, ensuring comfortable sound levels in occupied spaces. It can be integrated directly into ventilation ducts and is suitable for both residential and commercial buildings.

Practical Information

The sound absorption of the Spiro-SAFE silencer diameter 180 mm - length 600 mm (100 mm insulation) is achieved by mineral wool located between the inner and outer shell. Depending on the version, the wool thickness is 50 mm or 100 mm. The mineral wool complies with fire class A1 according to EN 13162, meaning the material is completely non-combustible.

The outer casing is made from high-quality galvanised steel to ensure durability and reliability, providing a robust and corrosion-resistant finish. The construction of the standard silencers is sturdy and functional. The walls are firmly shaped and resistant to mechanical stress during installation and use, resulting in a long service life, excellent sound reduction performance, and reliable operation across various ventilation projects.

Thanks to the round shape and smooth inner surface, the silencer causes low pressure losses within the ventilation system. This is important to prevent fans from being overloaded or consuming extra energy. The silencer can be used in both supply and exhaust air ducts.

Why Is the Premium Version Better Than the Standard Version?

The premium silencer offers several advantages over the standard version, making it more suitable for certain applications:

1. Wool Thickness: The premium silencer uses 100 mm thick mineral wool cut from rolls. This allows the insulation to conform better to the internal shape of the silencer for more uniform sound attenuation.
2. Central Core: From diameter 315 onwards, the premium silencers feature a central core. This core directs airflow through a perforated inner tube, increasing contact between sound waves and the absorption layer, leading to more effective attenuation of mid and high frequencies.
3. More Uniform Sound Reduction: The combination of flexible insulation, good fitting, and thoughtful construction ensures that the premium variant provides more consistent noise reduction across a broad frequency range. The standard version’s noise reduction can be slightly less uniform, particularly at lower frequencies.
