Spiro-SAFE Silencer Diameter 180 mm - Length 1200 mm (50 mm Insulation)

The Spiro-SAFE silencer diameter 180 mm - length 1200 mm (50 mm insulation) is a circular 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 ductwork. The silencer is designed to effectively attenuate noise from fans and airflow, ensuring that sound levels in occupied spaces remain comfortable. It can be directly integrated into ventilation ducts and is suitable for both residential and commercial buildings.

Practical Information

Noise absorption in the Spiro-SAFE silencer diameter 180 mm - length 1200 mm (50 mm insulation) is achieved through 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 non-combustible.

The outer casing is made from high-quality galvanized steel to guarantee durability and reliability, providing a robust and corrosion-resistant finish. The design of the standard silencers is solid and functional. The walls are firmly shaped to withstand mechanical stresses during installation and operation. This ensures a long service life, excellent noise reduction performance, and reliable operation across a variety of ventilation projects.

Thanks to its circular shape and smooth interior, the silencer causes low pressure losses within the ventilation system. This is crucial to prevent fans from being overburdened 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 that make it more suitable for certain applications:

1. Wool Thickness: The premium silencer uses 100 mm thick mineral wool that is cut from rolls. This allows the insulation to better conform to the inner shape of the silencer, resulting in more uniform sound attenuation.
2. Central Core: From diameter 315 mm upwards, premium silencers feature a central core. This core directs air through a perforated inner tube, increasing contact between sound waves and the absorption layer. This particularly improves attenuation of mid- and high-frequency noise.
3. More Uniform Noise Reduction: The combination of flexible insulation, precise fit, and thoughtful construction ensures the premium variant offers more consistent noise reduction over a wide frequency range. The standard variant may provide slightly less uniform attenuation, especially at lower frequencies.
