Diamante Models – DIA L 3GR
Lever espresso coffee machine with chromed brass groups. With mechanical movement.
Thanks to a special device which lets the hot water only into the group, keeps the brewing pressure always at the same level for a better exploitation of the coffee. Boiler single pressure gauge.
