We check it first in our unit before moving on to the manufacturing process. A Tube Diffuser is a type of pressure or pre-coating and is mostly used to filter and stratify beer that has been fermented, although other applications. We use technology to make it an excellent product. The Tube Diffuser thickness control the dirt in the filter.
