A false bottom is the best way turn a Sanke Keg into a mash tun if you plan to fly sparge and if you're direct firing your mash tun, a full width false bottom is the best prevention from scorching your grain and wort. This specific model, FB15H, is meant to be used with a bottom drained tun meaning that it will not require a diputube. This unit uses a single solid hinge all the way across the center of the false bottom.
NEW! We also now include a perforated center support for no additional cost to you. Due to the solid one piece hinge, we weld the pull ring to the hinge side of the false bottom so that the smooth side faces down and sits flush on top of the ring stand.
If you're comparing to other offerings out there, here are the vital specs: we start with 16 gauge (that's about 1/16" thick and we don't know of anyone making them thicker than this) 304 Stainless Steel sheet that has 3/32" holes punched over the entire surface on 5/32" centers.
We use a total of 12" of piano hinge that is spot welded at 10-12 locations per hinge and are also made of 16 gauge 304 stainless for strength and corrosion resistance. The hinges are necessary because the top holes that are typically cut in kegs are about 12" diameter and a full 15" disk would otherwise not fit.
Installation Requirements:
Note: The primary application is for 15.5 gallon, American Sanke-style Kegs, that measure approximately 15.75" diameter just above the area that transitions to the dished bottom. This false bottom will self-center at the area where it begins to curve into the dish. While it may fit into other keg styles such as the European 50L, Coors, or Hoff Stevens, we have not had the chance to test this (please don't assume it will fit)
Last thoughts.. FALSE BOTTOM STRENGTH! You'll occasionally read about folks collapsing their false bottoms in spectacular fashion. This happens more frequently in flat bottom pots where the disc is only held up by a few legs and doesn't have the same support around the circumference like in the case of a keg. That isn't to say that you can't collapse our false bottoms, or any others from any other vendor. Given the principals of hydraulics, you can actually apply enough vacuum using a March or Chugger pump to put 1000 pounds on top of the false bottom if you plug up your runoff hard enough. We've sold hundreds of units so far and have only had one customer report a collapse. However, we know what piece of mind is worth to many people so we're now including a center support with all false bottoms for no extra charge. This piece of tubular perforated is 2" in diameter and 1.75" tall. When installed in the bottom recess of the keg, the false bottom will hover over by 1/8" as to not interfere with positioning. It will make contact and provide support as soon as any weight is applied.
