I already have 1/2bbl for fermenting but this opens up a whole other realm of possibilities.
The link is live now, or should be.
The idea behind the adjustable arm is for just that, sediment free transfers and yeast harvesting.
I toiled long and hard over adding a gas port. But then I'd have to add a pressure relief valve and I'm afraid of the liability. You could, however, remove the blow-off tube after fermentation, attach a CO2 hose and use a couple psi to transfer your beer, but again, this unit does not have any sort of pressure relief and therefore I can't recommend you pressurize the vessel.
For racking, you'd start your transfer and then drop the arm down until it just picks up sediment and back off. After a nice sediment free transfer is made, you can swirl up the fermenter, drop the arm to the bottom and transfer out your yeast.
