ECM: portafilter sizes & compatibility

Every ECM machine in this database uses the 58mm portafilter standard.

We list 2 ECM machines, plus 21 items from other makers whose own documentation names ECM machines as a fit. Each entry says where its figures come from, so a claim here can be checked against the manufacturer rather than taken on trust. The group involved: E61 (58mm).

The ECM machines here are documented for non-pressurized (single-wall) baskets — see single vs dual wall baskets.

Other makers' parts listed as fitting ECM machines (21)

These are not ECM products. Each one appears here because its own manufacturer's documentation names ECM machines we cover — follow an entry to see the exact wording and the source it came from. Where a maker is silent about a model, we leave it off rather than infer a fit from matching millimetres.
