Robust-Aire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake, or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen-transfer as well as beneficial water movement and mixing.

For private ponds, lakes, reservoirs, stormwater retention ponds and other similar bodies of water. Robust-Aire systems allow for a continuous aeration of shallow to deep water.

  • No electricity in the water
  • No equipment floating on the surface, allowing for safe circulation on the water and a more natural look.
  • No shoreside power required, since the compressor can be installed far from the pond.
  • Ideal for deep water application
  • Low cost for large lake areas.
  • Minimal maintenance
  • 3 years warranty

RA5 (5 diffusers) and RA6 (6 diffusers) systems are also available; please contact us for a quote. 

Robust-Aire Diffusers

The diffusers are designed to produce fine air bubbles with minimum pressure. The base is made of durable plastic and comes with a seal that allows you to fill the base with gravel or other ballast substrate. The design keeps the diffusers at an optimal level above the pond bottom. The fittings are durable and bolted to ensure that the ballasted pipe does not come loose during installation or while maintaining the diffusers. A check valve with Viton seals prevents water from entering the pipe when the system is not in operation.

Self-Sinking Airline

Available in easy to handle rolls of 100 feet. Rolls are delivered in a box and come with our complete set of connectors, fittings and all necessary stainless steel collars. Additional lengths of ballasted hose ⅜″or ⅝″ are available when required (special order of SureSink™ Weighted Air Line Tubing).

  • 1 diffuser (RA1) : 100 feet of 3/8" self sinking tubing
