Kompresso = compress + espresso.  Cafflano kompresso is the world’s most compact and the lightest portable authentic espresso maker that uses a hydraulic system complied with Pascal’s principle to boost the extraction force of espresso. Pascal’s principle (the principle of transmission of fluid-pressure) is the principle in fluid Mechanics that States a change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid. This hydraulic Compressor of Cafflano kompresso is designed to retain high-pressure over 9 bar until espresso is fully extracted. In addition, the dual-mode pressure (pressing and pulling handles) maximizes the weight-force. [Key factors of Cafflano kompresso] – hydraulic water compression opposed to typical pneumatic air compression – unique compression-model design that maximizes force efficiency – consistent high-pressure over 9 bars.
