VST Precision Filter Basket

Now available in Ridgeless. VST’s new filters deliver consistent extraction performance over a wide range of concentration with reduced sediment. Each filter is designed to brew properly as a Normale, Ristretto or Lungo within a narrow gram capacity range. • All VST Filters are WARRANTED for ZERO DEFECTS • Holes are fabricated using a new micro-machine and finishing process. • 100% of holes are measured on every filter for min/max range limits on area and diameter to a precision of +/- 30 µm • All holes are measured for circularity, placement, square area and blocked holes • Filters are matched for total square area opening to +/- 5% to ensure identical performance (typical variances of standard filters range from 50-200% of nominal). • Hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck • Wide outlet angle to prevent filters from clogging, anti-wear design ensures uniform performance for life of product. • Improved structural integrity, will withstand deflection from pump cycling without premature fatigue failures (see VST Warranty)
