A puck screen sits on top of the tamped puck, between the coffee and the
shower screen. It spreads the incoming water across the whole bed instead of
letting it drill in wherever the stream happens to land, and it keeps the group
noticeably cleaner because grounds are not pushed up into the screen at the end
of the shot.
This is the ultra-slim version at 0.8mm — thin enough that it costs
almost no headroom in the basket, which matters more on a 57mm machine than on
a deep 58mm prosumer group. 316 stainless steel; Normcore also offers a 0.2mm
(200µm) Titanium PVD variant.
Sizing, and why 57.5mm
Normcore makes this screen in 49, 51, 53.3, 57.5 and 58.5mm. The screen sits
inside the basket, so it is always slightly smaller than the nominal
portafilter figure — 57.5mm is the one Normcore builds for the 57mm format, and
its “57mm Fits Lelit” collection states the products in it are “built to a 57mm
portafilter diameter and fits Lelit 57 Group espresso machines”.
That is the Lelit Anna here — the only LELIT57 machine
in this database. Do not substitute the 58.5mm screen: the Anna’s format is a
different size standard, not a rounding difference. See
why 58mm isn’t one standard.
Other items confirmed to fit machines this one fits — useful if you're kitting out a single setup. The count is how many of those machines overlap; nothing here is a new fitment claim.
