What's this? This is a diagram of the regulator that's inside of the Ultra Wine Saver. The reason for having a regulator is because we don't want to introduce the Argon gas into the bottle at a high velocity-a high PSI discharge would cause a myriad of problems:
It could cause the newly introduced Argon to be ejected from the bottle via the uncontroled turbulance.
If it weren't Argon, but say...Nitrogen/CO2 or some other gas the high PSI could cause the gases introduced into the bottle to actually combine with the Oxygen present in the bottle that you were attempting to displace.
Thirdly without a regulator, as the gas inside the cartridge began to run out, the "flow rate" of Argon comming out would never be consistant, but because it IS consistant regardless of how much Argon is left in the canister, the Flow Rate is 1.4 cubic inches per second; which in turn is about 7 cubic inches of Argon in a 5 second application....which in turn creates a 1 " inch layer in a 750 ml bottle of wine. 10 seconds would give 2 " inches of argon etc...
and lastly....the regulator makes a cool "gurgling" sound and who doesn't like gadgets that make cool noises? eh?
