58mm Bottomless Portafilter – Fits E61, Flair 58, ECM, Rocket, Sanremo, Synesso, Slayer, VBM (Black)

Designed to fit baskets of 58mm diameter, this bottomless portafilter is compatible with many E61 group machines — Casadio, Rocket, Elektra, Flair 58, Slayer, Synesso, Ascaso, Bezzera, BFC, Bianchi, Brasilia, ECM, Expobar, Faema, VBM, and similar models.

A bottomless portafilter (also called a naked portafilter) is the best tool for diagnosing extraction issues. With the spouts removed and the basket exposed, you can watch the whole extraction and spot channeling or uneven flow as it happens.

Made from 304 stainless steel with an anodized aluminum handle.

• Wide compatibility with E61 groupheads, Flair 58, ECM, Rocket, Sanremo, Synesso, Slayer, VBM, and more
• Bottomless design lets you monitor flow and diagnose channeling
• Stainless steel and anodized aluminum construction
• Lightweight, ergonomic handle
• No bottom plate means any basket size works — single, double, or triple

Please note: Channeling and spurting are common when you first switch to a bottomless portafilter, and aren't a defect. It's your coffee telling you there's room to adjust grind size, tamping, or distribution.
