Specification



STRUCTURE
 

 
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 surface to the inner core, allowing maximum dirt holding capacity and lowest pressure drop.
The whole JP washed series filters has been certified by NSF to the standard of NSF/ANSI 42.



FEATURES 
 
• NSF listed for ANSI 42 standard
•Through holes create real depth filtration 
•  Large flow and small pressure loss
•  High dirt holding capacity and long service life.
•  Pure, clean and washed material, no silicon, no fluorescence agent and no oil.

•  Temperature: 60℃(140℉)

TYPICAL APPLICATIONS

•  Residential water filter
•  Food & Beverage
•  Pre - RO

FLOW OF FILTER CARTRIDGE
 
 
The recommended flow for the filter cartridges in service is shown in the table (L/h for a 250㎜ filter cartridge)
Micron Rate(μm) 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
25 1200 670 300 150 130
50 1200 880 440 180 160
75 1200 1200 690 230 200
100 1200 1200 750 270 220
Notes:
1. The flow of each 250mm
10inchfilter 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).
