I.E - If filling a sml dive bottle or direct to gun using a compressor, is it easy to transfer moisture into the guns cylinder itself, if the filters are not doing the job properly, or have failed? How would you know about it, before the damage is done?
Hi Echo 1974
It would be a little risky filling with divers air if the dive shop had not checked their air moisture! But hopefully they always do as plenty of divers would complain! So they need to check and you need to check, simple as that. I have mentioned that you need 300 bar air for most applications and potentially the air you want is above 250 bar. Many dive bottle fills are only to a max of circa 232 bar and may not be of much use for guns that fill to 250 bar. I would certainly prefer to fill my air gun bottle from a pre filled source and not directly from even the size of the compressor mentioned above, most likely hard to control. As mentioned in a previous post I spoke about filters, drying agents, one way foster fittings on the filter cylinder and moisture indicating beads, it works well. Of course we humans don’t like spending money and perhaps never factor in our time, air quality filling our gun and perhaps the ramifications of wet air. Keep in mind wet air most likely will not rear its ugly head until the damage is done. In my case I have a functioning Yong Heng air pump which I upgraded but I know it will die sooner or later and likely when I absolutely need it! It’s now a backup for my 4 stage dive compressor; yes it costs money, guarantees fast dry high pressure air, very quick and since I’m not filling bottles from empty like a dive shop has very few hours on it. Low hours, excellent resale value.
