Optimize your aeration

FlexAir Pro enables you to optimize your aerationmaximizing  your oxygen transfer while minimizing your total cost of ownership—through our wide range of membranes, diffusers, and configurations. These including EDI-exclusive options like Matrix membranes, SuperStrut supports, ModuleAir configurations, and the unique Streamline system that integrates membrane, diffuser and lateral in one. 

Membranes

Custom-perforated, reliable membranes reduce replacement times and ensure oxygen transfer meets expectations. EDI engineers can advise you of the right membrane to empower your aeration to perform to your expectations, for as long as you expect. 

In addition to standards like:

  • EPDM and PTFE-coated EPDM
  • Polyurethane (PU) and high-temperature PU
  • Silicone

…we also offer our unique Matrix™ and Matrix Plus™ membranes, for which you can download spec sheets here!

improve aeration density and simplicity

with the EDI-exclusive aeration system that integrates membrane, diffuser, and lateral

STREAMLINE IS AERATION, SIMPLIFIED. 

StreamLine® is EDI’s patented configuration with unmatched system simplicity. Resulting in up to 33% reduction in system installation time compared to competing panel systems. Plus, membrane replacement can be completed in the field. 

  • Minimize in-basin components: StreamLine’s proven design elevates the industry’s standard practice by minimizing in-basin aeration piping and attached diffuser components. The self-contained FlexAir® membrane panels and the inline support system reduce stress points and potential material fatigue. In short, StreamLine delivers a new level of performance, simplicity and service life. 
  • Widest Application: StreamLine can be configured for any industrial or municipal application, tank size or geometry. 
  • Efficient: StreamLine’s geometry supports low flux rate resulting in ultra-high OTE performance. Precision die-cut NanoPore and MicroPore perforation for meeting air handling, OTE and pressure objectives. 
  • Reliable: Engineered materials for maximum chemical, temperature and UV resistance and advanced PTFE impregnated membranes for reduced fouling and optimum performance. 
  • Adjustable: StreamLine provides full solids suspension both above and below the diffuser grid. Elevation of the diffuser is adjustable to match blower performance.
