Filter Seals

Integrating Filtration and Sealing Technology

FilterSeal™ components are proprietary hybrid devices that integrate elastomeric sealing and filtration functionality into a single unit. These components consist of a custom-engineered composite structure that incorporates elastomers with fabric, metallic, or polymeric filter media. FilterSeal™ technology is designed to meet specific application requirements through a range of elastomer and filter material combinations.

FilterSeal™ Properties

Composite Structure

  • Primary components: Elastomer matrix with embedded filter media
  • Filter media options: Fabric mesh, metallic screens, polymeric membranes
  • Elastomer options: Silicone, fluorocarbon, and other application-specific elastomers

Filtration Capabilities

  • Particle size range: Macroparticles to molecular-level filtration (e.g., water vapor)
  • Customizable pore size and distribution
  • Filtration efficiency dependent on selected mesh/membrane characteristics

Sealing Properties

  • Conformable elastomeric profile for effective surface sealing
  • Customizable durometer and compression set resistance
  • Chemical compatibility tailored to application environment

Advantages of FilterSeal™ Technology

  1. Multifunctionality: Simultaneous sealing and filtration in a single component
  2. Design simplification: Reduction in part count and assembly complexity
  3. Cost-efficiency: Decreased procurement, inventory, and installation expenses
  4. Customizability: Tailored designs to meet specific performance criteria
  5. Rapid prototyping: Utilization of standard AS568 O-ring dimensions for accelerated custom manufacturing
  6. Versatility: Applicable across diverse industries, including automotive and food-grade applications

Design Considerations

FilterSeal™ components can be engineered to virtually any geometry or dimensional specifications. Design optimization involves the following factors:

  1. Operating pressure differential
  2. Flow rate requirements
  3. Temperature range
  4. Chemical exposure
  5. Mechanical stress and fatigue resistance
  6. Regulatory compliance (e.g., FDA, automotive standards)
