IMS DL200IM Integrated Membrane Shower Screen (De'Longhi)

verified · 10 August 2026

Fits these machines

The shower screen is the perforated disc in the roof of the group that the water passes through on its way to the puck. De’Longhi’s stock item is a simple dispersion screen; IMS’s DL200IM replaces it with a photo-etched integrated membrane — one solid piece of stainless steel with the perforations cut inside its thickness to a 200 µm filtering power.

Specs from IMS: 50.5mm external, 49.5mm internal, 9mm wall height, and a 5.3mm central hole.

Why the single-piece construction matters

Most screens are a mesh layered over a backing plate. Coffee oils work into the gap between the layers, and no amount of purging gets them out — which is why an old screen makes everything taste faintly stale. A photo-etched membrane has no layers to trap anything, so IMS’s claim that the surface is “totally smooth and completely free from rough spots or layers where dirt and coffee oils can deposit” is a structural fact rather than marketing.

The practical benefit on a small machine is more even pre-infusion. A 51mm basket is a narrow column of coffee, so water that arrives unevenly has very little depth in which to even itself out before it exits.

Fitment

This is a group part — it fits the grouphead, not the portafilter — so it is keyed by group here rather than by portafilter size.

The chain is manufacturer-primary at both ends. IMS states its DL series is what fits De’Longhi (“we offer specialized shower screens (DL series) that replace the stock dispersion screen”), and that “most De’Longhi home machines … use a 51mm group head”, naming the Dedica and La Specialista lines. De’Longhi’s own DLSC085 page states “51mm DIAMETER” and compatibility with “all De’Longhi La Specialista and De’Longhi Dedica Maestro models”.

A limit worth stating: IMS names the Dedica EC680/EC685/EC885 explicitly and refers to the Dedica and La Specialista lines generally, but does not enumerate every model. The cross-reference here is to the Dedica Maestro Plus, which De’Longhi itself places in that 51mm family. If you own a different De’Longhi, check that yours is a 51mm group before buying.

Pair it with the 51mm puck screen, which sits on the other side of the puck and protects this screen from grounds.

Also fits the same machines

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.
