We use Nitrogen to inert the Selective Solder, as well as spray flux. We have Onsite Nitrogen Generators.

Any thoughts?

Not entirely clear on your question. We don't coat any of our hardware (assemblies are coated prior to hardware installation), so if coating needs to be reworked after this, then hardware removal is needed.

any advantages over other nitrogen systems, like cost, maintenance, installation, etc?

fluxer requires normal shop pressure, around 100psi. Thanks for the infos, very useful.

The onsite generator drops approx. 30psi from the input. We feed ours 110psi and end up around 80psi in the tank, which we regulate to 65psi for the machines.

Sounds right, our actual pressure in the system is 120psi, the regulated to 100 in the machines.

we don't have a nitrogen generator installed yet. The solder wave supplier recommends 99.99%. we hare received several submissions for nitrogen generators that meet the requirements.

Agreed. If it's just a means of propulsion/ atomization the purity probably isn't too critical.

For fun ask the sales guy where they came up with that number. Or even the reasoning for using nitrogen. Don't expect quality answers.
