AFA® Pleated Septa

AFA® Pleated Septa, designed for condensate polishing, optimizes surface area for both filtration and backwash flow.

Since its introduction in 1990, the AFA® Pleated Septa has set the standard for condensate polishing. With its pioneering design and superior performance, the original pleated septa is tailored specifically for condensate systems. It delivers exceptional efficiency in both forward filtration and backwash flow, thanks to its meticulously optimized surface area.

Being constructed entirely from polypropylene material, the AFA® Pleated Septa is engineered for durability and longevity, providing a service life of over 5 to 8 years in high-temperature applications. This septa is designed to withstand its demanding environments, including fossil condensate deep bed pre-filtration and nuclear condensate systems. Its unique ability to facilitate effective CRUD removal in some nuclear radwaste applications further highlights its versatility and reliability.

AFA® Pleated Septa’s innovative design ensures a low-pressure drop while maintaining high filtration efficiency, making it the go-to choice for more than 100,000 installations worldwide. With low sulfate gaskets and an all-polypropylene construction, it offers excellent compatibility and minimal contaminant introduction.

Typical Applications:

  • Fossil condensate deep bed pre-filtration
  • Nuclear condensate deep bed pre-filtration
  • CRUD removal in nuclear radwaste systems

For condensate systems requiring unparalleled performance and reliability, the AFA® Pleated Septa remains the choice for efficient and effective filtration.
