1in Random Flow Generator – RFG100
A Random Flow Generator
With No Moving Parts.
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 water in different directions as it exits the nozzle.

- PATENT PENDING DESIGN
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.
| Model | Minimum GPH | Optimal GPH |
|---|---|---|
| 1in RFG | 320-400 | 720-1,000 |
The Random Flow Generator® Nozzle
The Only Random Flow Device With No Moving Parts.
The unique patented internal design of the Random Flow Generator® by Vivid Creative Aquatics, leverages fluid dynamics to randomly alter the direction of the flow as it exits the nozzle.
This internal helix design, pulls the central jet in on of 5 possible direction, but in only one direction at a time. The result is a broad wave-maker like motion but with no moving parts to wear out, no noise and no addition heat generated.
The Random Flow Generator® or RFG Nozzle can help to create a more natural, randomized flow pattern within an aquarium, pond, or other bodies of water.
Easy-Snap Fitting
This Reandom Flow Generator Nozzle is desgined to snaps onto a genuine Loc-Line® modular hose fittings. No tool required.
