Prior to the Generators, we bought tanks of N2. As long as you have an air compressor that can supply the generator, it's pretty much maintenance free. You change filters every year. In almost 15 years, other than changing filters, we've had to r

hello everyone, i'm looking for a spray gun that can withstand flux aggression. I made air controlled prototype for ersa wave machine, but air guns wear out quickly and start to leak. I was thinking about Binks model 95AR or something with stainless

We recently installed a new solder wave machine, The spray fluxer has a pressurized tank and because we use an alcohol based flux, the spray fluxer system must be fed with nitrogen. Anyone has infos on what installation is prefered to supply this mac

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

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.

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.

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