Features

• VST's new precision filters deliver consistent extraction performance over a wide range of concentration with reduced sediment

• Designed to extract properly as a ristretto, normale or lungo with minimal or no change in grind setting at a fixed dose 

• Filters are matched for total square area to +/- 5% to ensure identical performance

• (typical variances of standard filters range from 50-200% of nominal)

• All VST Filters are warrantied for ONE-YEAR and 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 (Unique QC report provided with every filter)

• All holes are measured for circularity, placement, square area and blocked holes

• 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)
