That's exactly what the KB90's daily backflushing routine needs, on a machine built for high speed and long operating days.\u003c\/p\u003e\n\u003cp\u003eThe KB90 works with a straight portafilter insert, the so-called Straight-In system, designed to reduce wrist movement and speed up the workflow behind the counter. The blind filter basket is made specifically for this version and can only be used with the matching Straight-In portafilter.\u003c\/p\u003e\n\u003ch3\u003eWhy such a simple piece of metal matters so much\u003c\/h3\u003e\n\u003cp\u003eDuring backflushing, the machine pushes water back through the brew group instead of forward – a process that only works with a sealed basket. Without an intact blind filter basket, the water would simply flow down through the open portafilter instead of flushing through the brew group and valves.\u003c\/p\u003e\n\u003cp\u003eOn a machine like the KB90, which gets backflushed multiple times a day in busy cafés, a blind filter basket that sits flat and isn't warped is part of the daily maintenance routine – not an extra, but a basic essential.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible with\u003c\/td\u003e\n\u003ctd\u003eLa Marzocco KB90 (Straight-In portafilter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBlind filter basket for backflushing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eLa Marzocco, Florence, Italy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem number\u003c\/td\u003e\n\u003ctd\u003eA03148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWho it's for\u003c\/h3\u003e\n\u003cp\u003eFor everyone running a KB90 daily whose blind filter basket is warped, no longer sits flat, or who simply needs a spare for the daily routine.
