Spiro-SAFE premium silencer diameter 500 mm - length 600 mm with core (100 mm insulation) without plug connections

Spiro-SAFE premium silencer diameter 500 mm - length 600 mm with core (100 mm insulation)

The Spiro-SAFE premium silencer diameter 500 mm - length 600 mm with core (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 sound levels in occupied spaces and technical rooms remain within acceptable limits. The silencer connection features a male connection (insertion end) on both sides with an integrated double EPDM lip seal, ensuring an airtight and reliable connection with round ventilation ducts.

Practical information

Sound absorption is accomplished through glass wool, which is positioned between the inner and outer casings of the silencer. Depending on the configuration, 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 guarantee uniform sound reduction along the entire length of the product. This ensures consistent attenuation even with variable airflow and smaller duct dimensions.

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

The construction is sturdy and functional, with a strong outer casing that withstands mechanical stress during installation and operation. The product code clearly provides information about the silencer type, insulation thickness, duct diameter (Ød1), and silencer length. This makes 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 100mm thick mineral wool cut from roll material. This allows the insulation to better conform to the inner shape of the silencer, providing more uniform sound attenuation.
2. Central core: From diameter 315 onwards, the premium silencers feature a central core. The core causes the air to flow through a perforated inner tube, increasing the 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, secure connections and thoughtful construction ensures that the premium variant delivers a more consistent sound reduction across a wide frequency range. In contrast, the standard variant’s sound reduction can be less uniform, especially at lower frequencies.
