Another way to generate more pressure than 1.5 atmospheres is to use compressed air. For example, a home coffee machine in Milanes collector Ambrogio Fumagalli uses an air pump to pressurize hot water for brewing coffee (during World War II). In 1938, Francesco IIIy made the llletta' Coffee Machine, a large commercial coffee machine based on the principle of compressed air. When the crossbar on the coffee machine was lifted before World War II, water was injected into the space occupied by the piston and pressed down, and the pressure on the piston injected water evenly into the coffee powder in the filter. this means that hot water can brew coffee before it boils without scalding the coffee powder. At the same time, Achille Gaggia, the owner of a cafe in Milan, used a similar method to brew coffee. This method is gradually adopted by other coffee machine manufacturers, so this new coffee machine is also gradually replacing the steam pressure coffee machine. Today, the application of this principle can still be seen on household machines-La Pavoni.
