Ducting carries air from your tent through the carbon filter and fan to the outside, and its quality affects both airflow and noise. This collection includes Combiconnect ducting from 102 to 406 mm and Combidec Combiconnect ducting from 102 to 356 mm, both in 10 m lengths, plus Sonodec Sonoconnect in 356 and 406 mm, an insulated duct that dampens sound and reduces condensation. Choose the same diameter as your fan and filter, keep runs as short and straight as possible and avoid sharp bends, which cost airflow. Connect with flanges & reducers and hose clamps, and pick a fan in extraction fans.
