PES Membrane Features
A membrane surface, an extended pleated area and a cartridge configuration selected together.
- A membrane for aqueous liquids.
- A hydrophilic PES membrane allows water-based liquids to wet the filtration surface and pass through the membrane.
- More surface within the cartridge.
- Pleating fits an extended membrane surface into a compact cylindrical format.
- Fit beyond the membrane.
- End connections, seals and cartridge dimensions complete the match between the filter and your housing.
Cartridge Construction
Explore the filtration layer, supporting structure and connections that work together inside the housing.
The filtration layer
The thin pleated membrane provides the filtration layer. Its selected grade defines the intended retention performance.
