Spiro-SAFE silencer diameter 100 mm - length 900 mm (50 mm insulation)

Spiro-SAFE sound attenuator diameter 100 mm - length 900 mm (50 mm insulation)

The Spiro-SAFE sound attenuator diameter 100 mm - length 900 mm (50 mm insulation) is a round sound attenuator made of galvanized steel, available in various diameters and lengths, used in ventilation and air handling systems to reduce noise transmission through air ducts. The attenuator is designed to effectively dampen noise from fans and airflow, 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 sound attenuator diameter 100 mm - length 900 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, meaning the material is completely 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 attenuators is sturdy and functionally designed. The walls are solidly formed and resistant to mechanical stress during installation and use. This results in a long service life, excellent noise reduction performance, and reliable operation in a variety of ventilation projects.

Thanks to the round shape and smooth interior, the sound attenuator causes low pressure losses in the ventilation system. This is important to prevent fans from being overburdened or consuming extra energy. The attenuator can be used in both supply and exhaust air ducts.

Why is the premium variant better than the standard variant?

The premium sound attenuator has several advantages over the standard sound attenuator, making it more suitable for certain applications:

1. Wool thickness: The premium sound attenuator uses 100 mm thick mineral wool cut from a roll. This allows the insulation to better conform to the inner shape of the attenuator, ensuring more uniform sound attenuation.
2. Central core: From diameter 315 upwards, the premium attenuators are equipped with a central core. The central core directs the air through a perforated inner tube, increasing contact of sound waves with the absorption layer. This particularly improves attenuation of mid and high frequencies.
3. More uniform sound reduction: The combination of flexible insulation, good fit, and thoughtful design ensures the premium variant offers more consistent sound reduction across a wide frequency range. With the standard variant, sound reduction can be somewhat less uniform, especially at lower frequencies.
