Flow recommendations
The RFG Nozzle will handle far more flow than the "Optimal" GPH recommendations, so we encourage you to experiment and test the limits of the RFG Nozzles.

The Random Flow Generator™ Nozzle
The internal structure of the RFG Nozzle is comprised of a 5-vane helix that spirals nearly the entire length of the nozzle. Each vane of the helix is connected to an eductor at the base. Together, they form a set of internal channels.
The channels work to randomly direct the flow in one direction or the other as it exits the nozzle.
The RFGS40MM is design to snugly fit on to the end of standard 40mm PVC pipe. No glue and no re-plubming – just slip it on.
