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.  JPL series has straight multi-hole from surface to the inner core, which performance a maximum dirt holding capacity and lowest pressure drop.

FEATURES 
 
1) Through holes create real depth filtration
2)  Large flow and small pressure loss
3)  High dirt holding capacity and long service life.
4)  Pure material
 
MAIN TECHICAL SPECIFICATION

4)  Pre - RO
5)  Other applications

TABLE 1

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)

Notes:
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).
