Spiro-SAFE Silencer Diameter 125 mm - Length 1200 mm (50 mm Insulation)

The Spiro-SAFE silencer diameter 125 mm - length 1200 mm (50 mm insulation) is a round silencer made from galvanized steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce noise transmission through air ducts. The silencer is designed to effectively attenuate noise generated by fans and air flow, ensuring a comfortable sound level in occupied spaces. It can be directly integrated into ventilation ducts and is suitable for both residential and commercial buildings.

Practical Information

The sound absorption of the Spiro-SAFE silencer diameter 125 mm - length 1200 mm (50 mm insulation) is achieved by mineral wool located between the inner and outer casing. Depending on the version, the wool thickness is either 50 mm or 100 mm. The mineral wool complies with fire class A1 according to EN 13162, meaning the material is non-combustible.

The outer casing is made of high-quality galvanized steel to ensure durability and reliability, providing a robust and corrosion-resistant finish. The construction of the standard silencers is sturdy and functionally designed. The walls are solidly formed and resistant to mechanical stress during installation and use. This ensures the silencer has a long service life, excellent noise reduction performance, and reliable operation across various ventilation projects.

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

Why Is the Premium Variant Better Than the Standard Version?

The premium silencer has several advantages over the standard silencer, making it better suited for certain applications:

1. Wool Thickness: The premium silencer uses 100 mm thick mineral wool cut from rolls. This allows the insulation to better conform to the inner shape of the silencer, resulting in a more uniform sound attenuation.
2. Central Core: Starting from diameter 315, premium silencers feature a central core. The core directs airflow through a perforated inner tube, increasing the contact of sound waves with the absorption layer. This leads to more effective attenuation, especially of mid and high frequencies.
3. More Uniform Noise Reduction: The combination of flexible insulation, good fitting, and well-thought-out construction ensures the premium variant provides a more consistent noise reduction across a wide frequency range. The standard version’s attenuation can be slightly less uniform, particularly at lower frequencies.
