Pleated Microporous Filter Cartridge

Filtration membrane material:
PP microporous membrane: wide chemical compatibility, acid and alkali resistance, and meets FDA food grade standards
PES microporous membrane: good hydrophilicity, high temperature steam sterilization
PTFE microporous membrane: hydrophobic/hydrophilic dual use, high temperature and chemical corrosion resistance

GF filter membrane: high porosity, high temperature resistance, used for pharmaceutical grade filtration

Nylon membrane: good hydrophilicity, alkali resistance, high strength

Support structure: There is a PP skeleton and support mesh in the filter element, and the adhesive-free hot melt welding technology is used to ensure fiber-free shedding and high sealing

End cover/interface form: supports multiple end types such as pointed and flat heads. The shell and central cylinder are made of PP (or PFA and other materials)

Sealing material: O-ring material can be made of silicone, EPDM, NBR, Viton, fluorine-encapsulated, etc., which can be adapted to different chemical media

Specifications

Filter element length: 2.5″, 5″, 10″, 20″, 30″, 40″ (10″≈254mm).

Outer diameter: Common 69mm (2.75″), and 83mm and 131mm large diameter.

Filtration accuracy: 0.04μm (PES bacteria grade), 0.1, 0.22, 0.45, 1, 3, 5, 10, 20, 30, 50, 75, 100μm.

Filtration area: 10″Normal about 0.65m², a certain model, such as 131mm×40″, can reach 9m².

Maximum working pressure difference (forward): can reach 0.3–0.42MPa (≈3–4.2bar) at room temperature, and can be as high as 1.6MPa for strict application.Maximum reverse pressure difference: Common 0.2–0.28MPa (≈2–2.8bar).

Working temperature: PP/PES ≤80–85°C, PTFE can reach above 90°C, PFA type can even reach 170°C.

Steam sterilization temperature: PES/PTFE/PFA type can withstand 121°C steam disinfection ≥30 minutes, PTFE can withstand 100 sterilizations.


Advantages and Features

High filtration area & large flux: The folding structure has a high surface area and low pressure difference, suitable for high flow filtration

Deep gradient structure: decrease from the outside to the inside pore diameter, achieving high dust load capacity and interception efficiency

Hot press welding without adhesive: no chemical residue, no secondary pollution, suitable for food/medical

Strong chemical and biological compatibility: a variety of membrane materials are suitable for acids, alkalis, and organic solvents

High integrity index: The bubble point of the microporous membrane is ≥0.24–0.38MPa, ensuring reliable bacterial interception function


Application scenarios

Pharmaceutical/biological preparation terminal sterilization filtration (0.04–0.22µm)

Ultra-pure/drinking water, soft drinks, alcohol terminals and pre-filtering

Electronic manufacturing high-purity water pre-filter

Chemical/solvent/ink/resin filtration: Use PTFE/PFA membrane to adapt to strong corrosion environments

Air/gas sterilization pre-filtration (PTFE type 0.01–0.02µm)


Select suggestions

Select accuracy according to particle interception requirements: for example, select 0.1–0.22µm for sterilization filtration, and select 0.45–10µm for conventional pre-filtration

Consider medium and temperature: PES or PTFE for medical liquid/biological applications; PFA/PTFE for thermal/corrosive media

Dimensions match housing: Confirm the filter length, end cap and O-ring type supported by the filter housing used

Pressure requirements: When the positive and reverse pressure is large, the maximum working pressure difference ≥ the required model should be selected.

Sterilization characteristics: If you need to disinfect frequently, PES/PTFE can withstand 121°C steam and have a longer life
