I'm interested in the outcome as I have the same air assisted nozzle plumbed into an aquamist hsf2. Testing flow without air pressure on the nozzle and with the flow valve turned to minimum I get 400cc min.spraying into a gallon jug by activating the hsf test procedure. I have not verified for atomization but assumed that atomization should be fine by keeping flow down.

I also have a solenoid in the air line going to the air assisted nozzle that opens at the hsf activation.

I don't see how you have it connected but you may want to add an air solenoid in line going to each nozzle so as to avoid over spinning the turbos before 8 psi.

Why do you have a check valve if you are running a water valve? When closed it should prevent dripping.

Is your system maf based? Although the air returning through the system, I would be worried about the effect it had on metering.

I'm worried now about the pressure and atomization.
