pp cartridge mainly used and applied for the water filtration such as daliy life,industry,electroplating solution, oil etc - details see: https://www.machineto.com/10-pp-string-wound-water-filter-cartridge-10230193

1:General

it is made from company"s one of patent yarn called "rotor spinning of medium long pp yarn"and also called as OES yarn,because of a specific technology,precise and orderly winding on different materials of the porous skeleton and outside the loose inside the tight structure,it is with good deep filtering effects

1250-1270	28-30	50-120	0.5-200

3:performance index

operating pressure drop:0.1kgf/cm²

max.pressure proof:0.4kgf/cm²

max.pressure deop:2kg/cm²

max operating temperature:

pp yarns and pp core 60°C

pp yarn and stainless steel core 80 °C

absorbent cotton and stainless steel core 180 °C

glass fiber and stainless steel core 200 °C

Note:

A:the flowrate is measured from the wound pp cartridge sized 250 mm long with the pressure pp of 0.14kgf/cm^2,simulative particle content of 300ng/l

B:the initial precision for filtration is 95%

C: the flowrate of absorbent connon cartridge is 0.6time less than the listed value

D: the flowrate if glass fiber cartridge is 0.5time less than the listed value

4:the comparison between flowrate and filtration precision

Micro rating(μm)	1	3	5	10	20	30	50
Max flowrate(m3/h)	0.4	0.45	0.5	1.1	1.5	2.0	2.4
