## Notes

ECM's Mechanika MAX II is a heat-exchanger E61 prosumer machine. This entry is
**measured tier**: ECM's own page confirms the machine and its heated brew
group but prints no portafilter diameter, so the 58mm figure comes from IMS's
competition catalogue, which classifies ECM under "E61 & compatible groups"
and publishes its B70 baskets for the 58 / 58.4 mm tamper standard — a basket
maker's measured fitment. As a 58mm E61 machine it takes any standard 58mm
basket; the VST and IMS B70 baskets in this database fit. A firsthand ECM
statement of "58mm" would lift it to manufacturer-verified.

- https://www.imsfiltri.com/IMS-competition-Catalogue.pdf
  - Official IMS Filtri competition catalogue, read firsthand 2026-07-13. Its B70 (Ø 70 mm border, tamper 58 / 58.4 mm) list is headed 'E61 & compatible groups like ...' and names ECM among the brands — a basket maker classifying ECM as an E61 / 58mm brand and publishing the measured fitment. This is the measured basis for the diameter here.
- https://www.ecm.de/en/products/mechanika-max-ii/
  - Official ECM product page, read firsthand 2026-07-15. Confirms the Mechanika MAX II as a heat-exchanger machine with an 'additionally heated brew group', shipping a 'portafilter with double spout' and 'portafilter with single spout'. ECM's page does not print a portafilter diameter or the name 'E61', which is why this sits at the measured tier.
