Filter like the Pros, only on a smaller scale. Most small breweries and wineries use a large plate filter system to achieve clear beer or wine. Now you can do the same at home. Our new Plate Filter has a larger surface area, which means more yeast and particulate extraction. Each filtering session requires two pads at a time, and each pad must be the same micron to work. The product is pushed into the housing at 5 PSI and passes on either side of the filter housing, then gets forced through the pads to the center, where it is pushed out into your awaiting collection vessel, such as a keg or tank.
