Extraction duct for large-flow ventilator

The extraction duct allows to extract the smoke from large volumes. The duct has a total length of 6 m. It is possible to interconnect up to 6 ducts. There is no bulky adapter between the duct and the fan, it clings directly to the rear grille.

1 or 2 ducts in parallel

Easy 2000 can receive a single suction line. Easy 4000, because of the size of its shroud, can receive 2 suction lines in parallel (one on each side of the engine).
