Each new VST Precision Filter is optimized for use with specific capacities in dose weight of coffee. The 20g VST Competition filter is the the preferred dose used in WCE and WBC competitions, and in many specialty cafes and coffee shops.
VST’s precision filters deliver consistent extraction performance over a wide range of concentration with reduced sediment and simplified preparation. Each VST filter is designed to extract properly as a Normale, Ristretto or Lungo.
Built with unprecidented precision, all VST Filters are WARRANTED for ZERO
DEFECTS. Holes are formed 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 better than +/- 30 μm (+/- 15μm typical).
Each and every hole is measured for circularity, placement, square area and blocked holes.
Filters are matched for total square area opening to +/- 5% to ensure identical group-to-group performance. (Typical filters vary from -50 to +100%)
Hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck.
Wide outlet angle prevents clogging, anti-wear design ensures uniform extraction performance for life of product.
Improved structural integrity, will withstand deflection from pump cycling without premature fatigue failures
