I looked into nitrogen generators, it was 4 years back and I was trying to get 99.995 i think. About �20,000 for the generator then another �20,000 for the compressor you need to force the air in. I spoke with David Groome of BOC UK 01709 842358

We have an ERSA Versaflow Ecoselect selective wave soldering machine. It works well except it needs nitrogen. You can't even move the table around if your nitrogen tank is empty. The spec sheet says Required degree of purity: Nitrogen liquid 5.0

The manufacterer of our machine recommends 99.999%. At their presentation before we purchased the machine they showed an example of using different purity levels. When they whiched the supply to 99.99 and then to 99.95 you can visibly see the diffe

I might be wrong since I don't know this piece of equipment but I think ROL might be a better measure. For 63/37 it used to be 20 ppm ROL (residual oxygen level) was about what you needed for a reflow oven. This is to take full advantage of all tha

100 PPM or 99.99% purity is sufficient for any soldering application. There are a number of manufacturers that make PSA style nitrogen generators that are great systems for electronics applications. They are low maintenance and will pay for themselve

Hi Thanks, I am concern about Raw nitrogen purity level. When we receive it in our compony from a supplier. Regards, Ameen

We are using Nitrogen from Dewer tanks. We have purchased a generator from On-Site gas that we will be installing in 2 weeks. I guess Nitrogen purity could be an issue, but the company that sells us Nitrogen said it is five 9s (99.999%)

Anyone have any pointers on how to measure the purity level of the gas supplied to Selective Solder machines? We use both bottled gas and also have an N2 generator and would like to confirm that both are performing similar.

Folks, I am interested in knowing what level of Nitrogen purity you are running in your reflow ovens for standard SMT assembly? It seems over the last several years people are increasing the Oxygen level in thier reflow oven atmosphere. What purity L

What about nitrogen purity? Erza won't say anything other than you need 99.999% pure nitrogen. We are looking at another company that says the same. At a previous place we switched from dewers of liquid nitrogen to a single pass filter. I could see
