The newest type of espresso machine (espresso coffee maker) that is commercially available, air-pump espresso machines use compressed air to create the pressure necessary to force hot water through roasted, ground coffee to brew espresso.
How Air-Pump Espresso Machines Work
With an air-pump espresso machine, the user provides the hot water either fresh off the stove or from a previously prepared thermos. The compressed air may be produced by CO2 or N2O cartridges, an electric air compressor, or a hand pump.
Benefits of the Air-Pump Espresso Machine
An advantage of the air-pump espresso machine is that it is usually very light and relatively small, and thus more portable than other types of espresso machines (which usually require electricity).
