Description

The Wilo‑Sevio ELASTOX‑D 12 is a fine‑bubble aeration disc diffuser system engineered for efficient oxygen transfer and mixing in wastewater and sludge treatment. Featuring a spring‑loaded hoist restriction and automatic sealing, it ensures reliable membrane expansion and prevents fluid penetration into pipelines. With flexible perforation patterns, a wide control range, and durable EPDM or silicone membranes, the ELASTOX‑D 12 adapts seamlessly to varying basin geometries and operating conditions. Its energy‑efficient pipeline system guarantees ideal air distribution with minimal pressure loss, while easy installation and maintenance options enhance operational convenience. Designed for long service life and environmental safety, the ELASTOX‑D 12 delivers dependable aeration performance in municipal and industrial treatment plants.

  • Spring‑loaded hoist restriction: Ensures even membrane expansion for ideal air intake.
  • Automatic sealing: Prevents fluid penetration into the pipeline when not loaded.
  • Flexible perforation patterns: Three options allow adaptation to basin geometry and installation conditions.
  • Wide control range: Enables precise system regulation of air intake.
  • Durable membranes: Made of EPDM, microbe‑resistant EPDM, or silicone for long service life.
  • Energy‑efficient pipeline system: Guarantees ideal air distribution with low pressure loss.
  • Easy installation: Threaded nipple or saddle clamp mounting on square or round pipes.
  • Maintenance options: Includes dosing facility for cleaning/regenerating diffusers and detachable design for easy extraction.

For fine bubble aeration of various fluids such as wastewater and sewage or sludge, for the purpose of supplying oxygen and mixing.

  • Increased operational reliability thanks to spring-loaded hoist restriction of the plate diffuser to evenly expand the membrane for ideal air intake. Thanks to its special design, the air intake is sealed when the membrane is not loaded to prevent fluid penetrating the pipeline system
  • Ideal adaptation of the air intake thanks to three different perforation patterns
  • Greatest possible process-specific activation density by taking different basin geometries and installation conditions into account
  • High flexibility in the system control through very wide control range of the air intake
  • High quality and service life of the membranes thanks to the production of moulded products
