Acoustic Ducting | 300mm

SEAHAWK Acoustic Ducting – 300mm x 5m Cut fan and airflow noise in your grow room or larger commercial extraction setup with SEAHAWK Acoustic Ducting. Built with a multi-layer construction — perforated inner duct, steel wire coil support, polyester (Dacron) insulation and a sealed outer layer — it dampens sound at the source while keeping airflow efficient. Sized at 300mm (11–12 inch), this length is a natural match for larger extraction can fans and odour-scrubbing carbon filters, and comes individually boxed and ready to install. 🔧 What's inside Perforated inner duct: lets sound pass through into the insulation layer instead of travelling straight down the pipe. Steel wire coil support: gives the duct its shape and flexibility while staying collapse-resistant at this larger diameter. Dacron (polyester) insulation: absorbs fan and airflow noise. Unlike fibreglass, it's itch-free and safe to handle. Sealed outer layer: keeps the system airtight and helps limit condensation forming on the outside of the duct. ✅ Key features 300mm / 11–12 inch diameter x 5m length, individually boxed Sized to match large extraction can fans and odour-scrubbing carbon filters Reduces fan noise and airflow "whoosh" for a quieter grow room Polyester insulation – no itching or skin irritation when handling Flexible for routing around tight spaces and obstacles Works well alongside a silenced fan, or to further dampen an existing ventilation system 💡 Installation tips Stretch the duct out fully and avoid sharp bends for the best airflow and noise reduction Fix the duct firmly in place with a 300mm duct clamp, then tape over the clamp with a strong mylar or foil HVAC tape Sizing can flex slightly at this diameter, so a clamp keeps the fit snug on fans and filter spigots
