Asymmetric PES Membrane Filter Element
The Asymmetric PES membrane filter element series filter element is an improved high-throughput sterilization filter cartridge, made of unique anti-pollution asymmetric Polyethersulfone (PES) membrane.
The asymmetric pore structure provides high throughput. The high flow rate makes strong dirt holding capacity, and longer service life than other similar products.
- High Flow Rate, Long Service Life
- The Gradient Pore Size Greatly Improves High Dirt Holding Capacity.
- 100% Integrity Test Ensures Absolute Sterilization Effect.
- Broad Chemical Compatibility, PH Working Range 1-14
- No Binders And Surfactants Used, Effectively Reduces The Risk Of Precipitation.
- Flow Rate
- 500 GPM
- Micron Rating
- 5, 10, 25 μm
- Max Temperature
- up to 80°C
- High-purity water terminal filtration
- Sterilising filtration of medical infusions, injections, and other liquid pharmaceuticals
- Sterilising filtration of disinfectants
- Sterilising filtration of food and beverages
The asymmetric polyethersulfone (PES) pleated membrane microporous filter element uses a transparent amber amorphous PES resin known for heat resistance, dimensional stability, and chemical resistance.
PES also performs reliably under rapid temperature changes and shows strong long-term stability at high temperatures. Its combination of formability and performance makes it a widely used polymer across demanding filtration applications.
The filter membrane stack is built from folded polyethersulfone filter membrane paired with a diversion layer. In the A-type element, the end caps, shell, and center rod are polypropylene; in the B-type element they are PVDF, which allows use in high-temperature service.
All sealing surfaces use adhesive-free hot-melt welding, forming a fully unified seal that introduces no chemical contaminants.
- Imported membrane with high filtration precision and excellent element integrity
- High flux, high flow, and long service life
- Wide chemical compatibility across pH 1–13
- High-temperature resistance and excellent acid/alkali tolerance
- Each element is rinsed with high-purity water before leaving the factory
