Beer typically consists of larger pieces of things such as malts, hops, grains and debris. For that reason courser filters are usually more effective. When brewing beer it is more effective to start with a KLR 50 micron filter cartridge. The wort is made, and after cooling it is carefully poured into a fermentation vessel to avoid heavy sediment going into your brew. Next comes primary fermentation, and the beer is siphoned off the heavier deposits to a secondary fermentation vessel. Initial filtering, using the KLR 50 micron filter cartridge, is typically done after primary fermentation completes. If finer filtering is required, you can 'step down' the filtering through the KLR 20 micron and 10 micron filter cartridges, which are also available on this site.
Every kit comes with the following parts:
Filter Base: This is the gray, heavy-duty circular PCV piece that was hand machined.
Base Gasket: There are 2 of these in every kit to make sure you have a spare. The base gasket is the larger round piece of rubber with a hole in the center.
Filter Body: This is the clear plastic threaded container. It screws into the filter base, and holds the filter cartridge and filter seal in place.
NOTE: the fitting on top of the filter body is slightly slanted for a reason. Do not straighten it out.
Filter Cartridge: The filter cartridge is the white cylinder that goes inside the filter body, and there are two starter filters provided in your kit. The beer kit has a 20 and 50 micron filter included in it.
1, 5, 10, 20 and 50 micron filters are available for this filter system. 1 and 5 micron filters are typically used for filtering wine. The 10, 20 and 50 micron filters are typically used for filtering beer.
Filter Seal: This is a solid rubber disk. There are 2 of these provided in each kit. The filter prevents your home brew from simply passing through the top of the filter, thus forcing it to pass through the sides of the filter cartridge. The seal provides assurance that the liquid is being filtered properly.
