Aeration dramatically improves environmental conditions in your pond and is key to creating predictable biological performance in your pond. The key to aeration is to provide physical energy that help gas exchanges from deep in the water with the surface, resulting in a thriving environment for fish and other organisms. The Robust-Aire diffused air systems provide deep water aeration for lakes and ponds deeper than 8 feet. Compressed air is pumped directly to the bottom of a pond providing continous flow to the water's surface enriching the bottom with oxygen.

The Robust-Aire System features no electrical system in water and sits on the bottom of the pond making it safe for swimmers and boats. Robust-Aire can be installed remotely away from water's edge, resulting in cost efficient installation as well as the ease of mind of no electricity near the water. Most maintenance/inspection can be done onshore making the Robust-Aire System low maintenance. Air compressors can inject air up to 50 feet deep making it ideal for larger ponds and lakes.
