Spiro-SAFE Silencer Diameter 150 mm - Length 600 mm (50 mm Insulation)

The Spiro-SAFE silencer with a diameter of 150 mm and length of 600 mm (50 mm insulation) is a circular silencer made from galvanized steel, available in various diameters and lengths. It is designed for use in ventilation and air handling systems to reduce noise transmission through air ducts. The silencer is engineered to effectively dampen noise from fans and air flow, maintaining a comfortable sound level 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 150 mm - length 600 mm (50 mm insulation) is achieved by mineral wool located between the inner and outer casing. Depending on the model, the wool thickness is either 50 mm or 100 mm. The mineral wool complies with fire class A1 according to EN 13162, indicating that the material is fully 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 solid and functionally designed. The walls are firmly shaped to withstand mechanical stress during installation and use. This ensures a long service life, excellent noise reduction performance, and dependable operation across a wide range of ventilation projects.

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

Why Is the Premium Variant Better Than the Standard Variant?

The premium silencer offers several advantages over the standard version, 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 conform better to the inner shape of the silencer, resulting in more uniform noise attenuation.
2. Centre Core: From diameter 315 upwards, the premium silencers feature a centre core. This core directs air through a perforated inner tube, increasing contact between sound waves and the absorption layer. This enhances attenuation especially for mid and high frequencies.
3. More Uniform Noise Reduction: The combination of flexible insulation, precise fitting, and thoughtful construction ensures the premium variant delivers more consistent noise reduction across a wide frequency range. The standard variant’s noise attenuation may be less uniform, particularly at lower frequencies.
