Genuine AirMax ProAir™ 4 Diffuser Plate Replacement
Keep your pond aeration system performing at its best with this OEM replacement diffuser plate for the AirMax ProAir™ 4. When diffuser plates wear down over time, oxygen transfer efficiency drops—affecting water quality and pond health. This genuine replacement restores peak performance.
How It Works
The diffuser plate is the heart of your aeration system. It breaks compressed air into ultra-fine bubbles that dissolve efficiently into your water. Better bubble size means better oxygen distribution, improved circulation, and a healthier pond ecosystem.

- Maintains consistent aeration performance
- Durable construction withstands regular use
- Direct fit for AirMax ProAir™ 4 systems
