Spiro-SAFE Silencer Diameter 630 mm - Length 600 mm (100 mm Insulation)

The Spiro-SAFE silencer with a diameter of 630 mm and length of 600 mm (100 mm insulation) is a round 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 noise 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 through glass wool located between the inner and outer casing of the silencer. Depending on the version, 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 ensure uniform sound attenuation along the entire length of the product. This results in consistent damping, even with varying airflow and smaller duct sizes.

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

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

Why is the Premium Variant Better Than 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 conform better to the inner shape of the silencer, providing more uniform sound attenuation.
2. Central Core: Starting from diameter 315, the premium silencers include a core in the centre. This central core directs the air through a perforated inner tube, increasing the contact between sound waves and the absorption layer. As a result, mid and high frequencies are attenuated more effectively.
3. More Uniform Noise Reduction: The combination of flexible insulation, good sealing, and thoughtful construction ensures the premium variant delivers a more consistent noise reduction across a wide frequency range. In the standard variant, noise reduction can be less uniform, especially at lower frequencies.
