Lists the ergonomic portafilter with brass brewing unit and filter-basket options '8/16 gr' and '14/18 gr'; states the portafilter 'holds coffee filters up to a capacity of 21 g'. The page itself does not print the portafilter diameter — see the catalogue PDF source for the 58mm confirmation.

The Silvia Inox and Silvia Black highlights state verbatim: '14 gr. and 18 gr. filter baskets' and 'Professional tamper: black wood with stainless steel flat base 58 mm'. A machine supplied with a 58mm flat-base tamper and standard 14/18g filter baskets confirms the 58mm commercial portafilter standard.
