To maintain a permanently cylindrical shape with a stretched fabric duct, a metal spiral covered in fabric is inserted inside of the diffuser.
The spacing of the internal spiral is managed by longitudinal textile straps.
Helix ducts can be any length, but are made up of 5m long sections zipped together.
The spiral can be easily disassembled for maintenance purposes and it’s designed to suit most of our suspension styles.
The fabric duct is tensioned by a hook and pocket arrangement at both ends of the duct to remove wrinkles and maintain an aesthetic finish.
