Measure the connections on your extractor and carbon filter first. The duct must fit the flange and pass through the tent port. Insulated ducting needs extra room for its outer jacket; the connection size refers to the inner duct.
Our Combi Connect and Sono Connect range comes in 10-metre lengths, with model sizes from 127 to 406 mm. Air distribution ducts have different diameter and length combinations. Check the exact version: a larger duct cannot fix an undersized connection.
You do not have to install the full 10-metre roll. Measure the required route with generous bends and room for fixing. Extend the section you use and avoid kinks or sagging loops.
