Hello to all. I'm building a prototype of a portable air compressor system. I would like to place a membrane just after the tank drain that would allow the liquid water (condensate) to pass through into a canister. This membrane would allow the water to pass through by gravity. When the portable system is laid on its back or side (for transport) the water would stay in the canister and not migrate back into the tank. A "flapper" style valve would not work well because it would remain open in many of the orientations in which the system will find itself. Gore-Tex is only good for water vapor, not liquid water. Thanks!
