The KB90 is the ultimate evolution of the Linea PB form. Designed specifically to optimize the workflow for the barista in the world’s busiest bars by improving the ergonomics and features of the machine.The Straight-in Portafilter improves the movements of brewing and removes the strain on the barista that causes repetitive stress injuries. Efficiency is also increased thanks to Steam Flush: after each extraction, a burst of steam from the steam boiler purges the brew path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative function minimizes coffee residue in the group, and reduces the number of times baristas need to back flush during service. The KB90 allows for a new level of expression in machine design, based on 70’s retro design and the La Marzocco shield, the panels have been engineered so that virtually infinite customization combination can be created.
