# IMS E61200IM Integrated Membrane Shower Screen (E61 group) > Espresso compatibility data from EspressoFit.

IMS's **E61200IM** replaces the stock screen on an **E61 group** with a photo-etched **integrated membrane** — one solid piece of stainless steel with the perforations formed inside its thickness, filtering to **200 µm**. Specs from IMS: **60mm border**, 56.5mm body, 17mm external wall height. ## Why this entry exists now This screen has been on this site's backlog for a long time, blocked for a specific reason: IMS's shower-screen **product** pages give dimensions but never name a machine brand, so there was no sourced way to say which machines an E61 screen belongs to without inferring it ourselves. IMS's **Shower Code Guide** closes that gap. It states that its screens "are classified according to compatibility with the brewing group", and publishes the prefix-to-brand mapping directly — for the **E61** prefix it names Faema, SANREMO, Kees van der Westen, Wega, VBM, Expobar, Bezzera, BFC, Bianchi, Brasilia, D.I.D., L'Orchestrale, **ECM**, Fiorenzato, Grimac, Iberital, La Nuova Era, La Scala, Quality Espresso, **Rocket**, Royal First, SV-SAB, VFA, Bellezza and Lelit. That is the manufacturer naming the brands, which is the standard this database holds to. ## Which machines are cross-referenced, and why not more Only machines whose **own** manufacturer page confirms an E61 group are listed: the four Rocket models and two ECM models here that carry it. IMS's list also names **Lelit**, but does not say which Lelit models — and Lelit's own pages describe its home groups as LELIT58, L58E and LELIT57 rather than E61. Rather than guess which Lelit machines have an E61 group, none are cross-referenced. The same reasoning excludes Rocket's saturated-group models. IMS publishes its own caveat, and it is worth reading before you buy: "The most common products of each manufacturer are compatible as indicated, but there may be models that use different components which may not always fit some models of home espresso machines." ## Fitment basis This is a **group part** — it fits the grouphead, not the portafilter — so it is keyed by group rather than portafilter size. That is why an E61 machine and a Gaggia Classic, both 58mm at the portafilter, take completely different screens: 60mm border here, 55mm for the [Gaggia GA200IM](/parts/ims-ga200im-shower-screen-gaggia/). See [groupheads explained](/guides/groupheads/) and [the E61 group](/guides/e61-group/). ## Sources - https://www.imsfiltri.com/shower-screen/E61200IM.html - Official IMS Filtri product page ('E61200IM SHOWER SCREEN', Competition Line, Integrated Membrane), read firsthand 2026-08-10.
