Description:
Rubber blind Filter - 50mm for any domestic or commercial coffee machines.
Fits any machine with a portafilter that houses a *3-way solenoid valve in the group head or off the boiler.
Simply insert this rubber blind filter into your portafilter basket. ..add tablet or powder. It will clean both the coffee machine and the coffee group.
This rubber blind filter prevents the cleaning agent from escaping.
When you turn off the cleaning cycle - a vacuum causes the cleaning agent and bitter coffee residue to be expelled through the solenoid, which cleanses the coffee group.
*If your model does not have a solenoid it cannot be backflushed conventionally - but you can still use it to clean the shower screen, using the backflush technique.
