Nuova Simonelli Bottomless Portaflter (After-Market)
This aftermarket Nuova Simonelli bottomless or naked portafilter will fit commercial Nuova Simonelli machines (7.0mm fins).
Taste the difference a portafilter can make. The Barista can watch the coffee brew right from the bottom of the filter basket and immediately know if channeling occurs, signaling that a level tamp was not made, which makes this an invaluable tool for training. Most Bottomless Portafilters will accept 21 gram triple baskets since portafilter body depth is no longer an issue. This item comes standard with a 58mm 21 gram triple basket, but will also accept any other "standard" sized portafilter basket. Don't like the hole at the end of the standard handle? Add a chrome cap to complete the look of this portafilter.
