We are known for making the fastest brewers out there (within reason). The OREA V2 started a trend for "fast-flowing brewers", continued by the V3 and the V4 FAST. With this release, we don't look just at SPEED, rather we look at CONTROL. The regulators use the same design as our beloved V4 FAST base, with even contact points across the bed of the brewer and plenty of space for air and water to flow to ensure the brew never chokes/clogs/stalls. The difference from our V4 FAST is that each regulator has an intentional set max output flow rate - to let you control the contact time predictably.
