The AC Infinity Inline Duct Silencer – 4 Inch is a premium noise-reducing solution for inline fans used in hydroponic grow tents, bathroom ventilation, AV closets, and other HVAC applications. This duct muffler is engineered with high-grade neoprene foam in a wave crest “egg crate” pattern, reducing airflow and vibration noise by up to 50% without compromising ventilation efficiency.

Each unit features dual aluminium flanges that help absorb sound vibrations directly from fan output and input ducts, allowing for quiet operation in both intake and exhaust setups. The corrosion-resistant galvanised steel housing ensures reliable use even under high heat and humidity—ideal for Australian climates.

Its compact 15-inch body easily integrates into most 4” duct setups and offers seamless pairing with AC Infinity CLOUDLINE inline fans. Whether you're a DIY grower or a professional HVAC installer, the AC Infinity Duct Silencer helps you maintain a quieter, more controlled environment.

Features

  • Noise Reduction up to 50%: High-density neoprene foam in an egg crate pattern significantly cuts airflow and fan vibration noise.
  • Dual Aluminium Flanges: Engineered to absorb sound waves and provide snug duct fan connections on both ends.
  • Maximum Airflow Efficiency: Open-cell foam allows airflow to pass freely while reducing turbulence and noise pollution.
  • Durable Galvanised Steel Body: Rust-resistant and heat-tolerant—ideal for grow rooms, AV closets, and Australian conditions.
  • Compact & Versatile: Installs anywhere in your ventilation chain—before or after your inline fan.
