The Robust-Aire RA6 Aquatic Aeration System is THE superior product available today. The Robust-Aire diffused air system provides deep water aeration for ponds and lakes. Diffused aeration is an effective method of aeration for ponds with depths greater than 8 feet. By using compressed air injected directly into the bottom of pond, a continuous flow of water is moved upward and thousands of gallons of water are mixed with little expended energy. A Robust-Aire energy efficient compressor injects air to the bottom of your pond with weighted, SureSink air line and into the Robust-Aire diffuser assembly. The diffuser breaks up the air into micro bubbles which rise to the surface. The rising of the air bubbles creates current which transfers low-oxygen water to the surface, allows it to contact the atmosphere, and breathe. Temperature layers are disrupted and fish are able to inhabit the entire water column. Oxygen levels increase and harmful gases in the pond water are expelled. There is no disruption of the serenity of your pond setting, just the assurance that it is getting the oxygen that it needs.
Aeration dramatically improves environmental conditions in your pond and helps keep good water quality predictable. Beneficial bacteria reduce sludge and nutrients, and there are reduced incidences of undesirable algae and odors. Winter ice is not allowed to seal the pond surface and restrict oxygen and gas transfer. Aeration allows your fish to thrive in an optimal environment and fish populations experience improved growth rates and vigor.
System can be ordered without a cabinet or with a large ground cabinet (holds up to 2 compressors feeding up to 6 diffusers, including one 110CFM cooling fan per compressor). The compressors and associated cooling fan are available in 120 or 240 volt. Each diffuser comes standard with 100' SureSink tubing.
Selecting the right system for your pond or lake is easy in most instances our sizing chart. Click the 'Sizing Chart' link in Downloads to view the basic sizing chart. If your situation is unique we can provide a design for almost any lake. Tubing longer than standard 100' and tubing for the system installed away from the water's edge is available. Please, call for more information.
NOTE: The product includes special ordering instructions. Please read the 'Lift Gate Information' section above before placing an order. Product with Large Ground Cabinet option will be shipped on a pallet.
- Cost effective to purchase and operate for larger surface areas
- Lakes/ponds deeper than 8-10'
- Minimal evaporation of surface spray from floating units is not allowed
- 10 to 44% more water flow with the same volume of air comparing to other brands
- Unique design and configuration allows for high flow with small bubbles and less friction loss
- Base made entirely of recycled HDPE with sturdy walls, hand holds, large fill port for gravel, and locking vented fill plug
- Strain relief for tubing
- Check valve with Viton seal and hastelloy spring
- Low energy rocking pistons compressor with quiet operation and minimal maintenance
- Robust-Aire compressor can inject air 40 feet deep
- No electrical power is allowed in the water - especially important where swimming is allowed
- No electricity needed at the edge of the pond or lake - Robust-Aire can be remotely installed away from the water’s edge, air can be delivered to the water’s edge instead of electricity (call for more details)
- No floating equipment at the surface - boating is not hindered and the natural view of the lake can be enjoyed
