A&A Manufacturing Gamma 4 Cleaning Head Internal Is The Same Exact Cleaning Head As The Gamma 3 (G3) Style, Just Improved.
The Gamma 4 cleaning head can be adjusted to give you 4 different flow rates. Adjusting the orifice size does not require a tool.
The cleaning head has been improved with new locking tabs to increase the strength and allow for easy installation. If your pool surface color is changed in the future you can easily change the color ring that is attached to the collar to a different color. This technology can also be retrofitted to existing Gamma 3 systems.
