SEDIMENT FILTERS
- Sediment Filters are used to remove particles from water and protect downstream taps etc from clogging
- Sediment cartridges are resistant to attack by bacteria and chemicals and are suitable for a wide range of applications, including domestic, commercial and industrial.
CS & TS Pleated Cartridge Range
- Polyspun cartridges are commonly used as the final filtration for sediment as damage does not compromise the micron rating
- These depth filters have a very large surface area and better dirt holding capacity than pleated filters
- 5 & 1 Micron versions are also often used as the final filter before a UV as drinking water standards require a minimum of 5 micron depth filtration
- 25 Micron version is sometimes used in place of a pleated filter for those who prefer to just change filters without the need to clean them, the higher dirt holding capacity means more time between giving the filters attention
