[PSUBS-MAILIST] tampon filters

Alan,
Mine is a little different.  The motor is part of the compressor, direct drive.  The whole thing is half the size of the one in the video.  Same compressor pump though, three stage.

Steve,
>The compressor is a 24v Cornelius and I bought two of them on ebay and got them working.  The compressor is 1.9cuft per min at 3,000psi. and it came out of a US military aircraft so it is tiny and light.  It is about the size of a kids lunch box.  There is no place here for 150 miles to get scuba tanks filled.  It would be very troublesome to get air here, that is why I want my own air supply.

>>I have a bailout bottle with clean air, so I really only wanted the hp tank air to breathable for surfacing while the sub is full of smoke.  Odour makes no difference because it is for such a short time.  having said that, since I know  nothing about filtration, I will get a larger bail out bottle and use that for all emergencies.  Thanks'  for the input, that was very helpful.

>>But in a nutshell, if you're going to be breathing it, especially if you have to bail out at depth, I wouldn't be trusting my life to tampons... The activated carbon and molecular sieve are pretty cheap, and much more manly :). 
>>Using an old hydraulic cylinder also has high potential for adding odours to your air that no filtration will get rid of - there is some good stuff about that in some the Airspeedpress books on diy oxygen systems.

You need a BIBS of some sort, and the simpler the better, as smoke tends to unravel the nerves a bit with a couple of hundred feet of water over your head. What air do you need to pump?
