This stainless steel conical fermentor features a weld-free interior, a dump valve for removing yeast and sediment, and a rotating racking arm for transferring. Prior to bottling or kegging, you can dump your yeast and trub out of the bottom, making for a very clean transfer. This helps with a cleaner, crisper beer everytime! The lid has a removable soda keg-style hatch that is pressure capable, allowing you to easily transfer using CO2 to minimize air exposure. Optional casters and leg extensions are available as well. The 42 Gallon Fermenator is designed to ferment 1BBL at a time.Note - Conical will come with an airlock. Blow-off elbow not included.
