Spiro-SAFE silencer diameter 180 mm - length 900 mm (100 mm insulation)

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

The Spiro-SAFE silencer diameter 180 mm - length 1200 mm (50 mm insulation) is a round silencer made from galvanized steel, available in various diameters and lengths, used in ventilation and air handling systems to reduce noise transmission through air ducts. The silencer is designed to effectively attenuate the noise from 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

The sound absorption of the Spiro-SAFE silencer diameter 180 mm - length 900 mm (50 mm insulation) is achieved through mineral wool located between the inner and outer casing. Depending on the variant, 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 fully 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 functionally designed. The walls are solidly formed and resistant to mechanical stress during installation and operation. This ensures a long service life, excellent noise reduction performance, and reliable operation in a variety of ventilation projects.

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

Why is the Premium Variant Superior to the Standard Variant?

The premium silencer offers several advantages over the standard silencer that make 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 internal shape of the silencer, providing more uniform sound attenuation.
2. Central Core: From diameter 315 onwards, premium silencers are equipped with a central core. The core ensures air flows through a perforated inner tube, increasing contact between sound waves and the absorption layer. This results in more effective attenuation of mid and high frequencies.
3. More Uniform Sound Reduction: The combination of flexible insulation, precise fitting, and thoughtful construction means the premium variant provides more consistent sound reduction across a broad frequency range. The standard variant may exhibit slightly less uniform sound reduction, especially at lower frequencies.
