The Nanotech Portafilters are treated all over with a special coating like the IMS Nano screens and baskets to get perfect non-stick properties and a much better durability compared to a Teflon® coating. This coating is a kind of a mineral coating (silica) which is food safe and resistant to most chemicals. The result is a cleaner cup and of course, the portafilter is much easier to clean, you can just rinse with water.
This professional range of Portafilters is available as La Marzocco, Faema E61 and Simonelli model, all are 15° angled. They can be paired with a single- or double Nano spout.
