The water is sent under pressure into multiple “hydro cyclones” that generate a significant centrifugal effect. The sediments settle in the center of the vortex and accumulate in a transparent collector cleaned by simple emptying, without any other intervention on the operation of the filtration. The clean water rises to follow the original path to the main filter. The polyvortex is placed directly behind the pump, using the pressure to create the mini vortices.
