AFC Cap Diffusers

The AFC coarse bubble disc diffuser design includes top-quality materials and engineering to improve wastewater treatment. Municipal and industrial systems around the world use these diffusers because of their superior efficiency. SSI focuses on reliability and performance during every step of manufacturing to enhance the client’s experience.

Applications of Coarse Bubble Diffusers

SSI’s coarse bubble disc diffusers have the following applications:

  • Equipment: Clients most commonly use AFC cap diffusers in equalization tanks and aerobic digesters. These applications do not prioritize high-rate oxygen transfer efficiency.
  • Piping: Piping systems that use cap diffusers tend to have PVC, CPVC or stainless steel materials. Construction types can include drilled and tapped pipes, welded 3/4-inch FNPT SS or grommets.
  • Flow: The AFC cap diffuser’s non-clog design suits a variety of flow requirements. It can operate in intermittent and continuous conditions.

Please ask an SSI expert for more information about the uses of coarse bubble diffusers.

EPDM Compound Applications

AFC cap diffusers feature a black acrylic plastic created from an EPDM compound. SSI uses this same plastic in fine bubble disc diffusers because of its demonstrated results. It brings similar benefits to cap diffusers. EPDM materials have a compression molding process that includes a standard cure and low plasticizer content. During manufacture, SSI utilizes modern equipment with individual thermocouples and vacuum technology.

Features of AFC Cap Diffusers

Clients can also benefit from the following additional features of the AFC coarse bubble diffuser:

  • Low head loss: In operations involving normal airflow ranges (3-6 scfm), the AFC has an operating head loss of around 5-20 inches of water.
  • Non-clog design: The diffuser diaphragm opens under air pressure and closes when airflow stops. This design prevents particle clogging and backflow.
  • Advanced membrane engineering: A replaceable membrane with 10 perforation covers the diffuser base. It has a design centered around maximum bubble formation and dispersion.

These qualities and more make AFC cap diffusers an indispensable choice for a system installation.
