VST 22g coffee basket - ridged

Fabelaktig 22g basket fra VST som jeg har hatt i et par uker. Jeg seller bare fordi jeg har kjøpt en ridgeless some passer litt bedre i min portafilter.

Kan hentes i Stavanger.

Fra produsenten:

Experience uniform extractions across all groups for the first time – permanently. The essential espresso filter for those in search of the ultimate cup.   

Features

VST's 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 open square area)

All VST Filters are WARRANTED 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 +/- 20 µm (individual 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, patented 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)
