Have you lost the lid hatch for your Blichmann Fermenator? This lid hatch is the replacement you need to get your Fermenator conical fermentor back up and running! The lid hatch replacement comes with the lid hatch, which is shaped like and reminiscent of a corny keg center lid. However, the lid hatch has a spot for a pressure relief valve that is standard in the Fermenator. The replacement lid hatch comes with only the actual lid hatch and a sealing o-ring. In addition to this, you may also need a replacement Fermenator pressure relief valve assembly with o-ring and a lid filter spring.
