Rotating nozzle
Rotating nozzle
This nozzle type is used in particular prior to an inspection or rehabilitation as it provides a full-surface cleaning of the pipe wall.
This type of nozzle tends to form aerosols.
The cleaning performance is achieved as with other types of nozzles through a combination of rearward propulsion and cleaning jets. The cleaning of the pipe invert is performed by the radially arranged jets in the rotating middle section of the nozzle.
