String wound cartridges offer true depth filtration with high dirt holding capacity and extremely low media migration. It is manufactured using a high speed, continuous wind process which creates a superior one-piece filter with hundreds of diamond shaped tunnels that get progressively smaller from the outer diameter to the core. Finer particles are progressively trapped as fluid travels to the center of the filter allowing for much greater retention capacity than that which is associated with straight surface filter media of the same dimensions and porosity.

【Note】
A. The flowrate is measured from the wound PP cartridge sized 250mm long with the pressure drop of 0.14kgf/cm2, simulative particle content of 300 mg /l.
B. The initial precision for filtration is 95%.
C.The flowrate of absorbent cotton cartridge is 0.6 times less than the listed value.
D.The flowrate of glass fiber cartridge is 0.5 times less than the listed value
