  • All VST Filters are WARRANTED for ONE-YEAR and for ZERO DEFECTS
  • Holes are fabricated using a new micro-machine and finishing process

  • 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
