Dear Thomas and list, The filter I have is manufactured by a 'friend" of mine who lives in Sydney. I have in reality only used it a few times. Rick Weisse here in Darwin manufactures another one with a much larger diameter. So I just thought I would use the opportunity to get some feed back, from this list. I fill and blend my own gas at at Cullen Bay Dive here in Darwin. They are fastidious with O2 cleaning precautions. Interstate, I only go to Nitrox Facilities. The filter I have is turned out of brass, and has male and female din fittings. It has two components in it. When one takes into account that "clean air filters" are usually a few feet high. I have always wondered at the efficiency of the filter I described. Hence it's limited use. Thanks for your comments. Jeff the Darwinian here in Oz.
