Professional: a combination of style, quality and reliability. The machine is largely constructed of cast brass and is built to last. The large boiler ensures that lime scale deposits have minimal effect, meaning minimum maintenance is needed. By lifting the lever, a piston inside the group is raised, allowing water under pressure to infuse the coffee in the filter holder. The lever is then lowered, causing the piston to force the water through the coffee into the cup. The user therefore can vary the speed at which the water passes through the coffee, ensuring this latter is made exactly according to his own requirements. The machine is fitted with a steam jet interchangeable with the Automatic Cappuccino maker, for the preparation of cappuccino and hot drinks in general, and is equipped with a manometer to check the boiler pressure. The "Cappuccino Automatic" attachment ensures a perfect cappuccino every time. This device on the opening of a valve automatically sucks the milk from its container and brews it warm and perfectly frothed into the cup. Model Professional allows 16 cups of espresso to be made consecutively. Boiler and group in chromed brass, chromed base, safety valve, steam jet interchangeable with Automatic Cappuccino maker, sight glass, manometer. Handles: lever, filter holder, boiler cap, steam knob in ABS plastic. Drip tray and grill for cups in ABS plastic.
