The Air Still is a special type of pot still that uses air instead of water to cool the condenser, with an inbuilt fan that blows cool air over the cooling coils inside the top cover.
It is conveniently sized and looks a bit like a kettle.
The Air Still should be able to run for 10 hours (ie if running a water distillation).
If you are using the Air Still for purposes such as to filter out unwanted flavours of alcohol we recommend that you don't use alcohol that is more than 20-40%.
The Air Still is required to be run in a well-ventilated area. When doing alcohol distillations, it's not good to concentrate the alcohol fumes in a contained environment such as a cupboard.
