VCA 1/4" RFG Nozzle for 1/4" Loc-Line - Random Flow Generator

Does it rotate or have any moving parts?
No – the RFG design has no moving parts . This means you can enjoy the random flow pattern without having to worry about internal gears or parts getting stuck or worn out. 

 

 

 

How does it work?
The random motion of the flow created by the RFG nozzle is accomplished through fluid dynamics. There are no moving parts. The internal structure is made up of a helix of spiraling fins that run nearly the entire length of the nozzle.When water moves though the nozzle it creates an accelerated stream of flow that passes through the center of the nozzle. This stream acts like a solid rod that isolates the fins, forming a set of internal channels.Each channel is connected to its own educator at the base of the nozzle and draws in additional water. When one of these channels draws in a little more water than the others, it becomes the dominant channel.The dominant channel then bends the center stream into that channel, causing the bulk of the water moving through the nozzle to exit through that one channel for a short period of time, until the next channel because dominant.This process repeats itself over and over, as long as water is moving through the nozzle.  The end result is a nozzle that can vary the intensity and direction of the stream of water exiting the nozzle creating a more natural, randomized flow pattern. 

How much flow does the RFG need?
The RFG nozzle will create a random flow pattern at just about any flow rate, but because of the way it works it does defuse the flow to some extent. Becuase of this, we have our minimum flow rate recommendations and what we call our “optimal” flow rates for the 1/2in, 3/4in and 1in RFG Nozzles.Our optimal recommendations produce what we feel is a good balance between the total GPH supplied to the nozzle and intensity and rate at which the nozzle changes the stream direction. The RFG Nozzle will handle far more flow than than the “Optimal” recommendations, so we encourage you to experiment and test the limits of the RFG Nozzles.
