Spiro-SAFE premium silencer diameter 150 mm - length 1200 mm (100 mm insulation)

Spiro-SAFE premium silencer diameter 150 mm - length 1200 mm (100 mm insulation)

The Spiro-SAFE premium silencer diameter 150 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 spaces and technical rooms remain within acceptable limits.
The silencer connections on both ends feature a male connection (insertion end) with integrated double EPDM lip seals, providing an airtight and reliable connection with round ventilation ducts.

Practical information

Sound absorption is achieved by means of glass wool located between the inner and outer shell of the silencer. Depending on the version, the wool thickness is 50 mm for the standard and 100 mm for the PREMIUM-100 model. The mineral wool is flexible and cut from roll material, allowing it to conform closely to the shape of the silencer and guaranteeing uniform acoustic attenuation along the entire length of the product. This results in consistent damping, even with variable airflows and smaller duct sizes.

The outer shell 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, featuring a tough outer casing that withstands mechanical stress 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 correct silencer for any ventilation project, from residential construction to complex commercial installations.

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, allowing the insulation to better conform to the inner shape of the silencer and providing more uniform noise attenuation.
2. Central core: From diameter 315 mm upwards, the premium silencers are equipped with a central core. This core directs the airflow through a perforated inner tube, increasing the contact of sound waves with the absorbent layer. This results in more effective attenuation, particularly of mid and high frequencies.
3. More uniform noise reduction: The combination of flexible insulation, proper connections, and thoughtful construction ensures that the premium variant offers a more consistent noise reduction across a wide frequency range. The standard variant may show slightly less uniform attenuation, especially at lower frequencies.
