These have the same features as the C Series cartridge filters, but use larger internal cartridges with a greater surface area, with standard dimensions as filtering elements – 330 mm in diameter, 460 mm high for the whole cartridge, or 330 mm in diameter, 230 mm high for a half cartridge.
They are made of AISI 304 or AISI 316L stainless steel, and may come with the following types of cartridge:
* filtering only
* decolorate only (with only carbon)
* absorbent only (with silicates only )
* filtering / decolorate
* absorbent/ decolorate
* filtering/absorbent/ decolorate
based on the above, the various models can be used in different filtering processes.
