- Common materials include paper, synthetic fibers, wire mesh, or pleated membranes.
- Media type determines the filtration efficiency and compatibility with different fluids or gases.
- Support Structure:
- Provides rigidity and durability to the filter element.
- Includes perforated metal cores, wire mesh, or plastic frames to support the filter media.
- End Caps:
- Securely seal the ends of the filter element.
- Made from metal, plastic, or composite materials, ensuring compatibility with the operating environment.
- Seal or Gasket:
- Prevents fluid bypass, ensuring that all fluid passes through the filter media.
- Commonly made from rubber, silicone, or elastomeric materials.
