Polypropylene Filters Cartridges (Melt Blown) (PP) are available in a variety of strengths 0.2 to 50 microns, depending on the size of the sediment and the flow rate required. Measured in microns
(1 micron = 1 millionth of a metre)
Pleated sediment Filter Cartridges available in 1 to 50 microns - (PL10-1/10/50 micron etc) these filters have the advantage of being washable a few times thereby maintaining the flow rate and filter life.
String Wound Sediment Filter Cartridges (SW) (Polypropylene String) are available from 1 to 100 micron and are particularly effective in areas where the water contains large amounts of sand and sediment
