Spiro-SAFE Silencer Diameter 180 mm - Length 900 mm (50 mm Insulation)

The Spiro-SAFE silencer diameter 180 mm - length 900 mm (50 mm insulation) is a round silencer made of galvanized steel, available in various diameters and lengths, used in ventilation and air handling systems to reduce noise transmission through air ducts. This silencer is designed to effectively attenuate noise generated by fans and airflow, ensuring a comfortable noise level in occupied spaces. 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 900 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, meaning the material is non-combustible.

The outer casing is made from 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 designed for practical use. The walls are solidly formed to withstand mechanical stress during installation and operation. This ensures a long service life, excellent noise reduction performance, and dependable operation across a range of ventilation projects.

Thanks to its round shape and smooth interior, the silencer generates low pressure loss within the ventilation system. This is crucial to avoid overloading fans or causing additional energy consumption. The silencer can be used 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 silencer, 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 better conform to the internal shape of the silencer, resulting in more uniform noise attenuation.
2. Central Core: Starting from diameter 315, premium silencers feature a central core. This core directs the air through a perforated inner tube, enabling sound waves to have greater contact with the absorption layer. Consequently, mid and high frequencies are more effectively dampened.
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. With the standard variant, noise reduction may be less uniform, particularly at lower frequencies.
