Jaybirdô Ultimate CO2 Harvester Cap

with PRV, Gas In Ball Lock Post

(supply your own canning jar)


This Ultimate version takes our regular Krausen Catcher (SKU# 2841) and adds two important features:

         The ability to hook up an external CO2 source in addition to harvesting the natural CO2 produced during fermentation

         A Pressure Relief Valve (PRV) to blow off excess pressure

If your fermentation vessel needs more CO2 than your canning jar(s) collect, simply do this:

         Hook up a CO2 source to the ball lock post using a Ball Lock Connector

         Start by setting CO2 pressure regulator to 1 PSI. Increase as necessary

         Feed CO2 back into fermenter

Allows cold crashing of large and small fermenters with no backflush to ruin fermented product. No exposure to air!


         Accepts standard Cornelius (Corny) keg Ball Lock Connector (sold separately - SKU# 132)

         Works with all Ball, Kerr, and Mason brand wide mouth canning jars (sold separately)

         Metal components are 304 Stainless Steel
