Eaton’s BECO PROTECT FS FineStream™ pre-filter cartridge and the BECO MEMBRAN PS Wine™ membrane filter cartridges offer a two-stage pre-filtration system which protects downstream membranes.
In the first stage, a pre-filter from the Beco Protect FS range with a retention rating (ß ratio ≥ 5000) of 1 or 2 µm is used as a particle filter. In the second stage, a fine filter from the same range with a retention rating of 0.3 or 0.5 µm helps to ensure preparation of the wine for the next step (membrane filtration) by reducing the colloids, proteins and tannins that can result in premature membrane blockage.
