The AC Infinity Inline Duct Silencer 4″ is specifically engineered to significantly decrease airflow noise and vibration sound within grow room and grow tent ventilation networks. It is the perfect solution for growers utilizing high-output inline fans who need to maintain an incredibly quiet and stealthy cultivation environment. Inside, it features premium, high-density neoprene foam utilizing an egg-crate acoustic design that effectively absorbs traveling sound waves without restricting or hindering volumetric airflow (CFM / $m^3/h$). The exterior housing is constructed from heavy-duty anodized aluminum, delivering exceptional resistance to rust and corrosion typically caused by high-humidity grow environments. It is designed with raised flanges on both ends to ensure quick, stable, and airtight connections with flexible ducting or directly onto the fan using duct clamps.
Key Features:
High-Density Neoprene Foam: Professional-grade acoustic material that substantially reduces dBA noise thresholds without causing static pressure drops
Egg-Crate Acoustic Design: Sculpted surface that traps and dampens sound waves created by high-velocity air movement
Anodized Aluminum Build: Rugged yet lightweight chassis built to withstand the demanding temperature and humidity levels of indoor grow spaces
Aerodynamic Airflow Optimization: Specially structured to deliver maximum noise reduction while keeping air restriction at zero
Seamless Mounting: Precision-engineered collars allow for fast and completely airtight fitting to standard 4 in (100 mm) ducting lines
