| Thread Wound Cartridge
1.General:
Honeycomb-like thread wound cartridges, with textile fibre
yarn of PP, absorbent cotton and glass fibre wound by special
pattern onto Polypropylene, stainless steel or tinned steel
skeleton, are used for depth filtration of liquid media where
it has low viscosity and a little impurities. The cartridges
are mainly used and applied for the water filtration such
as for daily life, food and beverage, industry, electroplating
solution, chemical lotion, oil and painting etc.

【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.
