This Blichmann 15 gallon modular attachment will extend the capacity of a 27 gallon Blichmann F3 Fermenator™ to 42 gallons, the perfect size to brew a 1 beer barrel (31 gallon) batch. This is a weld-free extension that attaches to the pressure lid sealing system in the recent F3 Blichmann conicals.
This extension will not fit other brands of conical fermenters, and it will not fit older F1 and F2 Blichmann conicals. Some of the earlier F3 Blichmann 27 gallon conicals may require drilling two 1/4" holes to attach the extension.
The extension kit includes leg braces, the 15 gallon extension module, and a blow-off hose assembly with hose P-clips. The clamp, seal, and lid hatch of your present 27 gallon F3 Fermenator™ will be used with the extension. However, the option of switching the "lids" will allow you to switch from 20 gallon to 31 gallon batches using the same fermenator. One Fermenator™, two sizes. Think about it.
