This is the brand name of carbonation systems for use at home. They were invented during the early 1900s to add carbon dioxide (CO2) to drinking water. At that time they were called "apparatus for aerating liquids". The newer versions allow for incorporating flavored concentrates and before you know it - you have homemade carbonated, flavor drink or soda pop.
The initial machines made were rather large and were sold for the larger households of the upper classes of London, including the royal household.
