String Wound Polypropylene Cartridge Applications
The Sterling 2.5" x 20" 5 micron string wound filter cartridge is for a wide range of filtering applications, manufactured from FDA grade
polypropylene. These cartridges are very suitable for potable water
filtration. Ideal for removing very fine sediment right through to very
coarse sediment, at ambient temperatures. NOTE: Be careful when comparing
pricing - there are lower cost “INDUSTRIAL GRADE” polypropylene
cartridges being sold that are not meant for filtering potable water.
String Wound Polypropylene Cartridge Features
Double and triple length cartridges minimize change out time and eliminate
the possibility of blow-by as a result of using multiple cartridges in
conjunction with cartridge couplers.
Spun Polypropylene Depth Cartridge Construction/Rating
- The spun polypropylene cartridge is made by diagonally winding a
precise pattern of carefully selected fibers on a center core. The pattern
is designed to create hundreds of identical, tapered, spiral passageways.
During the winding, fibersare combed across the passage and locked in place
by succeeding layers. Solid particles are removed by entrapment in this
highly efficient filter media. Filtration takes place throughout the entire
cartridge, not just on the surface, so large amounts of contaminant are
trapped without a sudden rise in pressure caused by surfaceblinding. By
varying the wind pattern, cartridges are fabricated to give a
pre-determined micrometre rating.
