We built one for our field sprayer years ago before gps. Used a fire extinguisher tank, a belt driven air compressor with an adjustable relief valve, and a couple electric valves to switch booms. Run the air line to the bottom of the tank to agitate the foam and hook the out put to the top. Pretty simple.
