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.
