F3 FERMENATOR PRV ~10 PSI Unique Fermentation Weight for pressure relief when fermenting in Corny Keg

This factory replacement for the Blichmann F3 Fermenator PRV is a cool type of airlock that turned up the other day.  This piece of machined and polished stainless steel is weighted to hold back ~10PSI of fermenting pressure.   When Co2 pressure exceeds 10PSI the PRV will be forced up slightly and will hiss releasing the pressure.  It’s like an airlock or a blowoff tube but even better.  To use with a corny keg simply remove the PRV and drop it in.  You can install one in anything with some DIY, it needs to sit in a sleeve like the PRV sleeve on a corny keg.  If you have a different application in mind you’ll need to make a sleeve.  Direct replacement for the Blichmann F3 Fermenator, can be used for your own special DIY project.  Designed and engineered by Blichmann Engineering.
