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.

The RFGS150  is designed to snugly fit on the end of standard 1.50 in. schedule 40 PVC pipe with an outer diameter of 1.90in (48.27mm). No glue and no re-plumbing – just slip it on.
