[PSUBS-MAILIST] tampon filters

[hank pronk]

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.

Fair enough Hank, no worries. What compressor is it and where did you get it? Something small enough to go in a sub but still do HP is kind of rare. 
Cheers,
Steve

Steve,
>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.

>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 lost me here. A compressor? Why not tap into the HP system with a two charging blocks and clamp on scuba 1st/2nd stage regulators? 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?

>>>Gamma has an onboard hp compressor now.  Since I may need to breathe the air from the main hp tanks in case of smoke or passing gas :-)  I need to filter the air.  I am making a filter housing from a hydraulic cylinder and filling it with tampons.  I read that tampons work for this.  Is that true?  I hate buying tampons, !!
