Spiro-SAFE premium silencer diameter 160 mm - length 1200 mm (100 mm insulation)

The Spiro-SAFE premium silencer diameter 160 mm - length 1200 mm (100 mm insulation) is a round ventilation silencer made of galvanized steel, specifically designed for use in ventilation and air handling ducts. This silencer is engineered to effectively reduce noise generated by airflow and mechanical fans, ensuring that noise levels in occupied and technical spaces remain within acceptable limits.
The silencer connections on both ends feature a male spigot connection with an integrated double EPDM lip seal, creating an airtight and reliable joint with round ventilation ducts.

Practical information

Sound absorption is achieved by glass wool positioned between the inner and outer casing of the silencer. Depending on the model, the wool thickness is 50 mm or 100 mm for the PREMIUM-100 version. The mineral wool is flexible and cut from roll material, allowing it to conform well to the shape of the silencer and ensure uniform noise reduction along the entire length of the product. This guarantees consistent attenuation even with variable airflow and smaller duct dimensions.

The outer casing is fabricated from high-quality galvanized steel to ensure durability and reliability, providing a robust and corrosion-resistant finish.

The construction is sturdy and functional, featuring a solid outer shell resistant to mechanical stresses during installation and operation. The product code clearly indicates the silencer type, insulation thickness, duct diameter (Ød1), and silencer length, making it easy to select the appropriate silencer for any ventilation project, from residential buildings to complex commercial installations.

Why is the premium variant better than the standard variant?

The premium silencer offers several advantages over the standard silencer, making it better suited for certain applications:

1. Wool thickness: The premium silencer uses 100 mm thick mineral wool cut from rolls, enabling the insulation to better conform to the inner shape of the silencer and providing more uniform sound attenuation.
2. Central core: Starting from diameter 315, the premium silencers feature a central core. This core directs the airflow through a perforated inner tube, increasing the contact of sound waves with the absorption layer, which results in more effective attenuation of mid and high frequencies.
3. More uniform noise reduction: The combination of flexible insulation, proper connections, and thoughtful construction allows the premium variant to provide more consistent noise reduction across a wide frequency range. The standard variant’s noise reduction can be less uniform, especially at lower frequencies.
