Description

Blauberg Silencer SD 125/600 – Round Duct Noise Attenuator

Optimise your ventilation system’s comfort and performance with the Blauberg Silencer SD 125/600. Engineered for attenuation of duct-borne noise, it works in tandem with sound-insulated fans to deliver whisper-quiet airflow in residential, commercial and light-industrial settings.

Robust Construction for Lasting Performance

• Galvanised steel casing resists corrosion and mechanical damage
• Filled with non-flammable mineral wool and covered to prevent fiber release
• Rubber-sealed flanges ensure airtight connections and eliminate leaks
• Available in multiple lengths to suit diverse duct runs

Superior Acoustic Absorption

Featuring a perforated inner core and 50 mm acoustic lining, the SD 125/600 silencer delivers targeted noise reduction where it matters most. Peak attenuation reaches 15 dB at 500 Hz and 28 dB at 1 kHz, dramatically lowering fan whine and HVAC hum without impeding airflow.

Easy Installation & Flexible Placement

• Mounts directly to 125 mm round ducts using standard clamps
• Any orientation: vertical, horizontal or angled
