??? I don't think I would mess with anything that was not from an INDUSTRIAL application. There are devices to compress gas for welders and the like as I said, not always CNG, sometimes H2. I know these exist because I have seen them in use, I just have no knowledge of the brands, models and types of pumps that would be best for this purpose.
My intent would be to have something that is not only industrial and designed for constant use but also something that is reliable, rebuildable, efficient (compressing to 3600psi is much less efficient/reliable than to say 1000psi) and preferably already designed to be pumping some sort of flammable gas.
I don't think I would mess with things that don't handle flammable materials, scuba compressors handle semi flammable materials but I don't think 02 counts.
We will have to wait for someone that has messed with industrial applications, there are many many compressors out there so there has to be something that meets my criteria that I could get on the used market. When it comes to something flammable I see no reason to reinvent the wheel when its already been done for 60 years.
