FLO is a study into the effects of flow dynamics in extractions. A patented design created by Varia and refined by Kurasu, FLO utilises a two part assembly with interchangeable flow screens which provided variations in flow rate, flow paths and contact time.

FLO also utilises an extremely difficult manufacturing process to insulate the two layers of Stainless Steel to produce a cool touch exterior wall allowing for a minimal design without a handle for a more comfortable, intuitive and efficient workflow as well as optimal temperature stability internally.
