Re: Air absorbtion by charcoal.

I agree that a mechanical compensator would be vastly more effective
than a physiochemical solution. For purely academic interest do you
think the charcoal would have a thermal effect whereby the temperature
rise from compression would be absorbed by the charcoal (aided by the
large surface area) thus reducing the pressure. Are there other
materials with enhanced surface area which would give better heat
transfer than activated charcoal?

A 5 psi difrerential would not cause perceptible temperature change
around equilibrium. You get immense surface areas from aerogels and
metal-organic frameworks. You can dial in interactions by diddling
the surface chemistry. Push come to shove, the answer to his problem
was somewhere between a pneumatic dashpot (critically damped bellows)
and a muffler.
