Product Description
Why choose the 500 mm ring?
- Wider 500 mm diameter for greater coverage
- Designed for even air distribution around the full ring
- Suitable for ponds, vats and large filter chambers
- Helps support bio media and fish during warmer months
A larger ring spreads airflow more evenly, reducing dead spots and improving circulation across the pond floor.
Fit notes
- Connect to a compatible air pump using suitable airline and hosetail fittings.
- Position flat on the pond base or within a filter chamber.
- Ideal for higher air output systems or larger ponds.
If you’re running multiple diffusers, use a manifold with air taps to balance flow and prevent excess back pressure on the pump.
Maintenance
- Check periodically for reduced airflow.
- Rinse or clean if debris builds up.
- Ensure airline connections remain secure and leak-free.
Hose size: 18 x 28 mm
Hose tail : 19mm.
The air rod has a T-piece 19mm in the middle for a better air distribution compared to a connection on only one side.
