Spiro-SAFE silencer diameter 160 mm - length 600 mm (50 mm insulation)

Spiro-SAFE sound attenuator diameter 160 mm - length 600 mm (50 mm insulation)

The Spiro-SAFE sound attenuator diameter 160 mm - length 600 mm (50 mm insulation) is a round sound attenuator, a ventilation accessory made of galvanized steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce noise transmission through ductwork. The attenuator is designed to effectively dampen noise from fans and airflows, ensuring a comfortable noise level in occupied spaces. It can be integrated directly into ventilation ducts and is suitable for both residential and commercial buildings.

Practical information

The noise absorption of the Spiro-SAFE sound attenuator diameter 160 mm - length 600 mm (50 mm insulation) is achieved by mineral wool located between the inner and outer shells. Depending on the version, 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 shell is made of high-quality galvanized steel to ensure durability and reliability, providing a robust and corrosion-resistant finish. The construction of the standard attenuators is robust and functionally designed. The walls are solidly formed and resistant to mechanical stresses during installation and use. This results in a long service life, excellent noise reduction performance, and reliable operation in a wide range of ventilation projects.

Thanks to the round shape and smooth interior surface, the sound attenuator causes low pressure losses in the ventilation system. This is important to prevent fans from being overloaded 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 offers several advantages compared to the standard attenuator, making it more suitable for certain applications:

1. Wool thickness: The premium sound attenuator uses 100 mm thick mineral wool cut from rolls. This allows the insulation to better conform to the interior shape of the attenuator, providing more uniform sound attenuation.
2. Central core: From diameter 315 upwards, the premium attenuators feature a central core. The core guides the air through a perforated inner tube, increasing the contact of sound waves with the absorption layer. This effectively attenuates especially mid- and high-frequency noise.
3. More uniform sound reduction: The combination of flexible insulation, precise fit, and thoughtful construction ensures the premium variant offers a more consistent noise reduction across a wide frequency range. The standard variant may have slightly less uniform attenuation, particularly at lower frequencies.
