These arrestors are simply oil soaked cotton air breathers, with wire mesh around the outside. That simple.
K&N makes them for about 40-50 dollars. Some however, are far more expensive.
Also there are the industrial type flame arrestors. Now those are expensive. I have called two companys, that make these industrial arrestors. The tech. reps. have asured me that the boat type air cleaner, would be fine for hydrogen, and vapor type aplications.
To reiderate, the arrestors ment for boats, are a reusable air breather, (cotton, not paper element). Must have wire mesh type reinforcement, and must be oil soaked. These are available in JC Whitney, ON LINE, and @ autozone. Typicaly used in riceys (a cone shaped filter), or race cars (a circle style filter).
The piont is that air and gas can go in, and flames or spark and heat can not get out.
As for the pictures you speek of, they are in Thrivals Folder.
