Series description
Wilo-Sevio ELASTOX-T


Aeration system consisting of tube diffuser and pipeline system to distribute compressed air. On-site downspout or air intake pipe can be connected directly to pipeline system.


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


Compressed air generators input air into the pipeline system via the air intake pipe. The pipeline system evenly distributes the supplied air to individual diffusers. Air is evenly input to the fluid free from coalescence via a sewage-resistant membrane.

The aeration system is composed of one or more aeration fields. An aeration field consists of several components.

The tube diffuser is composed of a floodable supporting tube with an overlying pipe membrane.

The pipe membrane is fixed to the supporting pipe using two fastening clips. As a result of the membrane’s good resilience, its perforation remains sealed when the membrane is not loaded. This reduces fluid entry into the pipeline system.

Tube diffusers are installed on the pipeline system in pairs using a tie rod. Square pipes are used for the pipeline system.

The energy-efficient pipeline system guarantees ideal air distribution with low levels of pressure loss. It is detachable, height-adjustable and adapted to the characteristics of the basin and other plant technology.
