draft brewer beerbrite filtration system for filtering with home brew keg system draft brewer the filter housing connects between 2 kegs, and non-carbonated beer is forced (with co2) from the first keg, through the filter, and into the second ‘bright’ keg. the system includes 2 filter cartridges; a 5.0 micron filter which removes particulates such as hop debris, proteins and trub material that would clog the fine 1.0 micron filter. so easy to use; simply connect the 2 ball locks, and turn on the gas - the beer will flow and you will know that you’re beer is clear.
