String wound filter cartridge consists of multi-hole frames wound closely with textile fibers. Diverse kinds of filtering precision can be realized by controlling the winding density. As the outer bore diameter is larger than the inner one, the filter cartridges have a good deep-level filtering capability.  JP series has straight multi-holes from the surface to the inner core, allowing maximum dirt-holding capacity and lowest pressure drop. The holes are now with slope design (25micron -200micron), creating swirling flow in the filter housing, which prevents particles from settling at the bottom and provides more benefits to the water. Various micron rates and sizes are available: 1micron, 5micron, 10micron, 25micron, 50micron, 100micron, 2.5"x10", 2.5"x20", 2.5"x30", 2.5"x40", 2.5"x50", 4.5"x10", 4.5"x20" etc. 
The whole JPW series filters has been certified by NSF to the standard of NSF/ANSI 42.

The recommended flow for the filter cartridges in service is shown in the table (L/h for a 250㎜ filter cartridge)
Micron Rate(μ m) Viscosity
1cs(water) 30cs 60cs 120cs 250cs
0.5 70 60 40 25 -
1 150 90 60 40 -
3 300 120 80 50 -
5 500 170 120 60 45
10 800 300 140 70 60
20 1100 540 220 100 95
30 1200 670 300 150 130
50 1200 880 440 180 160
75 1200 1200 690 230 200
100 1200 1200 750 270 220
1. The flow of each 250mm(10inch)filter cartridge should not exceed 1200 L/H (317G/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 (1.45 – 4.35psi ), 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 (14.5 – 21.8psi).
