/VST Filter Basket, a ridgeless 20-gram double filter basket that usually works with a tamper of 58mm. It suits most E-61 group heads and any group measuring 60mm in diameter. It’s applicable to machines like La Marzocco, Nuova Simonelli modelas (those using standard portafilters), Synesso, La Marzocco Swift Grinder, La Cimbali, Faema and Rancilio, but requires a bottomless portafilter.
VST Baskets deliver consistent extraction performance over a wide range of concentration. It properly and expertly extracts among most bottomless portafilters, such as Rancilio, La Marzocco, La Cimbali, and Nuova Simonelli, Quick Mill, Giotto, Izzo, Rocket, Vibieme, Isomac and many more. Additionally, baskets come uniquely coded for manufacturing QA and product authenticity. 2-D bar-code stores factory measurements, quality reports and even image data.
VST Filter basket comes with fabricated holes using new micro-machine and finishing process. We measured each and every single hole for the minimum and maximum range limits on area and diameter to a precision of +/- 30 µm. Most noteworthy, we calculate for circularity, placement and square area before sold and considered fit for baristas. Hole pattern is centered to +/- 1.0 mm while placement is oriented for a uniform extraction all throughout the entire puck.
Its anti-wear design ensures the uniform performance of product for life with wide outlet angle that prevents filters from clogging. The structural integrity of the filter basket has also improved making it stand the test of time. It can now able to withstand deflection from pump cycling without occurrence of any premature fatigue failures.
VST FILTER BASKET FEATURES:
- Firstly, filter basket delivers consistent extraction performance
- All matched for total square opening to +/- 5%. This is to ensure identical group-to-group performance where typical filters vary from -50 to +100%.
- For placement, circularity, square area and blacked holes, we measured each and every hole.
- Even more, all VST filters are warranted for zero defects
