It consists of multi-hole frame wound closely with textile fibres.with large flow ,small pressure loss and high residual loan. - details see: https://www.machineto.com/sf-string-wound-filter-cartridge-cotton-or-pp-10025061

STRUCTURE

String wound filter cartridge consists of multi-hole frame wound closely with textile fibres.Diverse kinds of filtering precision can be realized by controlling the wining density.As the outer bore diameter is larger than ten inner one,the filter cartridges have a good deep-level filtering capability.

FEATURES

Eliminate effectively the suepended objects and particles i the liquid.With large flow and small pressure loss.With high residual loan and long service life.Can resist higher filtering pressure.Provide different kinds of materials for filter cartridge according to the nature of liquid to be filtered,thus ensuring the good compatibility between them.

MAIN TECHICAL SPECIFICATION

Dimension:Outer diameter Ø65^±2mm Inner diameter 28mm 30mm

Pressure:0.5MPa

Temperature:60°c(for polypropylene)

120°c(for stainless steel core,cotton fibre)

FLOW OF FILTER CARTRIDGE

The recommended flow for the filter cartridges in service is shown in the table(L/h for a 250mm filter cartridge)

micron rate	Viscosity	Viscosity	Viscosity	Viscosity	Viscosity
(μ m)	1cs(water)	30cs	60cs	120cs	250cs
0.5 1 3 5 10 20 30 50 75 100	70 150 300 500 800 1100 1200 1200 1200 1200	60 90 120 170 300 540 670 880 1200 1200	40 60 80 120 140 220 300 440 690 750	25 40 50 60 70 100 150 `80 230 270	- - - 45 60 95 130 160 200 220

Note:

1.The flow of each 250mm filter cartridge should not exceed 1200L/h,otherwise its precision may be affected.

2.The flows shown in the above table are only the recommended values.The actual flow of the filter cartridge in service may change due to the liquid nature,temperature,the nature of the eliminated particles,the contents of the particles,etc.

3.It is recommended that a new filter cartridge used in the first time should work under a pressure drop of 0.1--0.3 bar,while the final pressure drop for the filter cartridge exchange is set at 2.5 bar.For the filter cartridge whose precision is lower than 10μm,the pressure drop for the filter cartridge exchange had better be set at 1.0--1.5 bar.

APPLICATION

Mainly used for the purification of water treatment in food and drinks,electronic,pharmaceutical,petroleum and chemical industries.
