Innovative, Flat-lying E61 Bottomless Portafilter Compared to traditional bottomless portafilters, the IKAPE KKLUO portafilter features a flat design, with a flat, straight back that allows it to be placed directly on the coffee bar countertop. This eliminates the need for a portafilter holder or a coffee tamper mat and tamper station, allowing for direct espresso puck preparation. Made of Pure Metal, Black Electroplated Finish. Sturdy and Durable The IKAPE flat-bottom E61 portafilter features an aluminum alloy handle and a stainless steel head, finished with an electroplated all-black coating. It is sturdy, durable, and built to last. Equipped Precision Basket, Extract Unique Flavor Espresso The IKAPE bottomless portafilter is equipped with a precision basket featuring a double-layer design and a compass-like geometric pattern. This design creates a layered, centrally focused structure, resulting in a uniquely layered flavor profile in the extracted coffee. Additionally, the inner basket's dense mesh is easy to clean, producing a cleaner and more compact coffee puck. Compatible with 58mm E61 group head espresso machines The IKAPE E61 portafilter features a completely new mold design and is compatible with almost all brands of E61 grouphead espresso machines, such as ECM, La Marzocco, Lelit, Rocket, San Remo, Bezzera, Gemilai, etc. Note: Not compatible with Rancilio and Flair 58+ coffee machines.
