English PRODUCT DESCRIPTION
• Drainage connection as the terminating connection of all aerator pipes with a connec -
tion for the drainage line. This can be used to drain off the condensate that can form
during aeration.
• Pipe coupling with rubber ring seal as a plug connection for connecting the individual
PVC components. The pipe coupling for securing the aerator pipes on the air distributor
must also be equipped with a stainless steel clamping ring.
4.2.2. Base support
All pipes on the basin bottom are secured by the base supports. They also make it pos -
sible to level the aerator group.
There are two different base supports:
• For securing the stainless steel air distributor
• For securing the aerator pipes and the PVC drainage connection
4.2.3. Disc aerators
The disc aerators introduce the supplied air into the liquid. The air is distributed across
the entire membrane surface and released through the perforated membrane. The disc
aerator consists of several components.

• Fiberglass-reinforced plastic threaded ring for securing the membrane to the membrane
support. The threaded ring and aerator housing are matched to each other in such a
way that the threaded ring can be easily loosened even after years of use, allowing the
membrane to be replaced.
• The polyacetal separation ring prevents the membrane from sticking to the threaded
ring. This ensures that the membrane can be easily replaced.
• The EPDM membrane with perforations across its entire surface for optimal air inclusion.
• Fiberglass-reinforced plastic membrane support, which holds the membrane in place.
• The EPDM non-return valve protects the aerator system from penetration of the liquid if
the membrane is defective.
• Fiberglass-reinforced plastic aerator housing with integrated anti-rotation lock
• NBR O ring for sealing the disc aerator against the aerator pipe
• Fiberglass-reinforced sliding closure for easy installation and removal of the disc aerator
