RE: [PSUBS-MAILIST] P SUBS, Ambient air systems

["Pierre Poulin" <pipo305@hotmail.com>]

Hi Seth,

Scrubbers are used mainly in an emergency case. You are free to use them or 
not...

To equalize pressure inside an dry or wet ambient design you can use a scuba 
regulator and "plug" it on the sub. The excess of pressure when you go to 
surface will go thrue the regulator. It will also put air inside the sub 
when you go down. You can also have a manual valve to change the air inside 
the sub if you stay at the same deepth for to long.

I hope this help!
