HRV mixed flow forward
enz golden jet® nozzles with forward impact angle of approx. 45° on the pipe wall as well as a front-guide jet (on request) and 3 retro-thrust jets cause a corkscrew-like advance through the clogged pipe. While the front nozzles loosens and the semi-radial nozzles disintegrate the residues, the thrust nozzles are driving the nozzle head forwards and simultaneously pushing the waste material backwards.

- Cleaning of house connecting pipework from inside to the drain system
