Glass fiber string wound filter cartridge
Glass fiber string wound filter is made of fiberglass yarn (also called baked glass fiber) and stainless steel inner core, the structure is same as string wound filter, it is used for high corrosive or high temperature liquid filtration, with standard 10", 20", 30" and 40", micron rate of 0.5-100 microns, manufactured in China.

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.
Glass filter string wound is made of fiberglass string and stainless steel core, it has same structure as ordinary string wound filters but much higher temperature and corrosive tolerance.
Yarn Material: baked glass fiber
Core material: stainless steel
Sizes: 2.5"x20", 2.5"x30", 2.5"x40"
Norminal rates: 1micron, 5micron, 10micron, 25micron, 50micron, 100micron.
FEATURES
• High temperature tolerance
• High crossive resistance
• High flow and low pressure loss
• High dirt holding capacity and long service life.
MAIN TECHICAL SPECIFICATION
• Dimension: Outer diameter Ø63±1mm Inner diameter Ø 28mm or Ø 30mm
• Maximum operating Pressure: 0.5MPa （72.5psi）
• Maximum operating Temperature: 399℃（750℉）
TYPICAL APPLICATIONS
• Strong inorganic acids filtration
• Organic solvents filtration
• Oils filtration
• Oxidizing Agents filtration
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).
