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 | Suggested Minimum GPH | Optimal GPH |
|---|---|---|
| Single 1/2in RFG (RFG050 ) | 120-150 | 300-450 |
| Two 1/2in RFGs (RFG050) | 250-400 | 640-670 |

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 20mm to 1/2 Slip-Fit Pipe Adapter is compatible with 20mm PVC pipe and the 1/2in RFG nozzle or 1/2in Loc-line® modular hose
