Spiro-SAFE premium silencer diameter 560 mm - length 600 mm with core (100 mm insulation) without plug connections

Spiro-SAFE premium silencer diameter 560 mm - length 600 mm with core (100 mm insulation)

The Spiro-SAFE premium silencer diameter 560 mm - length 600 mm with core (100 mm insulation) is a circular ventilation silencer made from 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 sound levels in occupied and technical spaces remain within acceptable limits.
The silencer connections on both ends feature a male connection (spigot end) with an integrated double EPDM lip seal, providing an airtight and reliable connection to round ventilation ducts.

Practical information

Sound absorption is achieved using glass wool situated between the inner and outer casing of the silencer. Depending on the type, the wool thickness is 50 mm or 100 mm for the PREMIUM-100 model. The mineral wool is flexible and cut from roll material, allowing it to conform well to the shape of the silencer and ensuring uniform sound attenuation along the entire length of the product. This results in consistent damping, even with variable airflows and smaller duct sizes.

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

The construction is sturdy and functional, with a strong outer shell resistant to mechanical stresses during installation and use. The product code clearly provides information about the silencer type, insulation thickness, duct diameter (Ød1), and silencer length, making it easy to select the right silencer for any ventilation project, from residential buildings to complex commercial applications.

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 roll material. 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, the premium silencers are equipped with a central core. This core forces the air through a perforated inner tube, increasing contact of sound waves with the absorption layer. This especially enhances attenuation of mid and high frequencies.
3. More uniform sound reduction: The combination of flexible insulation, effective sealing, and thoughtful construction ensures the premium variant delivers a more consistent noise reduction across a wide frequency range. The standard variant may have slightly less uniform attenuation, particularly at lower frequencies.
