The Air Still Pro is a small table-top still with a reflux column that uses air instead of water to condense vapour
It is similar to the Air Still, in that they both condense vapour with the same coil condenser and a fan motor that draws air through the condensers fins.
But the main difference is the Air Still Pro has a reflux column. This gives distillers the option to run the still as a pot still (just like the Air Still) or use it like a reflux still (like the T500).
Pot Still Mode is great for making dark spirits, botanical gin vapor infusions, stripping runs and taking cuts. In this mode the ABV output is the same as the Air Still, starting off at ~80abv and continually dropping during the run.
