Description : 
String Wound Filter Cartridge | High-Flow Depth Filtration for Borehole Water | BlueSpot Water

 Features : Buy BlueSpot Water String Wound Filters for superior depth filtration. Ideal for high sediment areas and borehole water. Available in 10", 20", and Big Blue sizes.

It reliably acts as a pre-filter to remove common particulates like sand, silt, dirt, and rust particles.

 

 What does it do: The String Wound Filter Cartridge is a high-performance sediment removal solution. Unlike surface filters, this cartridge utilises a unique yarn-woven design to provide genuine depth filtration, capturing sediment throughout the entire filter structure. This makes it exceptionally effective in areas with high levels of suspended solids, such as borehole water and industrial applications across South Africa.

Good to know:

Designed for effective sediment removal, capturing up to 99% of particulates from your water supply.

The depth filtration process allows the filter to hold significantly more sediment than standard melt-blown filters, making it ideal for high-sediment water and extending the service life.

Available to fit all common filter housings, including 10-inch, 20-inch, and Big Blue (Fat) sizes.
