There are various versions of the La Pavoni Bar espresso machines. This model, the Pavoni Bar V, uses a solenoid operated brewing group. The Bar models can also be equipped with a lever brewing group or a manual operated group head.
The brewing group on the Pavoni Bar V is fed from the heat exchanger (HX) coming from the boiler. The water feeding the brewing group enters the brewing group, true the first chamber with the filter. From there, when the solenoid valve is open, the water can flow towards the brewing group chamber and from there it can flow out of the brewing group towards the shower screen.
The portafilter gasket used on this brewing group had a outer diameter of 73mm and a inner diameter of 57mm. The thickness of the standard gasket is 8mm. Once the group wears out it is possible that you require thicker portafilter gaskets or filler gaskets.
The shower screen installed is fixed with a central screw. The outer diameter of this shower screen is 57,5mm and is made up out of 2 filter layers. A big hole diameter and a wire mesh filter.
The portafilter which is used on this brewing group is the standard commercial portafilter. This portafilter has a ear orientation of 45 degree and a ear thickness of 5,6mm. This portafilter can NOT be used on domestic La Pavoni espresso machines.
