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.





1 in. PVC Slip Fitting

The RFG100  is designed to snugly fit on the end of standard 1 in. PVC pipe. No glue and no re-plumbing – just slip it on..
