Flow recommendations
For the strong, punchy randomization flow effect, supply each Random Flow Generator® Nozzle with the Suggested Optimal Flow Rating or more. For broad diffused and randomized flow, your target should be closer to the suggested minimum flow.

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.




Includes Metric PVC Pipe Adapter

The Included 25mm to 3/4in Slip-Fit Pipe Adapter is compatible with 25mm PVC pipe and the 3/4in RFG nozzle or 3/4in Loc-Line® modular hose
