Viscose

This is the most commonly used media for gravity filter systems. The coarse short staple fibres of the wood pulp based media create a relatively weak product. However, the gravity feed mesh belts sufficiently support the versatile filter paper. Viscose suits most fluids offering nominal filtration from 15 - 50 micron.

Polypropylene Needle felt

Filter rolls are extensively used for machine tool coolants and cutting & lubricating fluids found throughout the metalworking industry. Our polypropylene media is widely used in applications where standard Viscose rolls are not strong or efficient enough or where extra fine filtration is required. When in operation the polypropylene filter rolls filter the contaminant, building up an efficient filter cake.

Polyester Needle felt

This media is ideally used in fine contamination applications where high dirt loading is expected. The depth of the media provides better levels of filtration, typically 10 - 15 micron nominal in addition to longer filter life compared to SBPP.
