Parts

We carry replacement and maintenance parts for Koenders aeration systems, including diffusers, airline, diaphragms and service items for windmill, solar and electric setups. If you tell us your model and what needs replacing, we will help you find the right part or a compatible upgrade.

Start with your system model and the component that needs attention, such as the diffuser, airline or compressor diaphragm. Contact us with those details and we will confirm the correct replacement part. Keeping wear items fresh helps your system keep moving air and oxygenating the water.

A drop in air output usually points to a wear item such as a worn diaphragm, a blocked or damaged airline, or a fouled diffuser. Replacing the worn part typically restores output. Reach out with your model and symptoms and we will help you diagnose which maintenance part to order.

Aeration systems benefit from regular checks of the diffuser, airline and compressor components, with wear items replaced as needed. Service intervals vary by model and site conditions, so contact us with your setup and we will advise on maintenance. For general aeration guidance, see our guides at /learn.
