The rotary jet cleaner works according to the recoil principle. The 2-armed cleaner rotates 360° around its own axis and can be easily mounted on the bottom of the basin or by a bracket above the channel. The movement is realized by the flanged, insulated stainless steel swivel joint. The cleaning medium is waste water, which is taken from the middle sump by a pump. By means of the specially developed, adjustable blasting nozzles in combination with the rotating movement of the jet, exceptional cleaning performance is achieved. The rotation speed can be flexibly changed by adjusting the nozzles Especially in rainwater basins with round, square or polygonal shape, the rotary jet cleaners develop their full efficiency.
