Hi,
Here is my Laminar nozzle with 6 inch Diameter pipe. I have to add a Pre-filter with 4" Diameter pipe so that i only have to clean that and not disassembling of complete nozzle. Cutter and RGB lighting is still in progress.
The nozzle is connected to tap water with low pressure so the laminar arc is small... Actual arc is 5.8 feet high and almost 12feet long.
