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 odours. 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 vigour.
Robust-Aire diffused air systems provide deep water aeration for ponds and lakes. Diffused aeration is an effective method of aeration for ponds with depths greater than 2.5m. By using compressed air injected directly into the bottom of the pond, a continuous flow of water is moved upward, and many cubic meters of water are mixed with little expended energy. A Robust-Aire™ energy-efficient compressor injects air in 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.
The compressor of Robust-Aire™ can be installed at a distance from the edge of the water, and pumps air through the Sink Sure™ air line to the diffuser. This arrangement is preferred over a complete integrated system. It is safer and can result in lower installation costs.
Available in 1 to 6 diffuser head assemblies, Robust-Aire Diffused Aeration is consistent with other product offerings by Kasco: quality design, efficiency, & professional assistance, along UL, CSA, and CE safety markings.
Our compressors and the associated cooling fans are available in 120V or 240V, 60Hz power or 220V, 50Hz power.
Systems come standard with our large cabinet, but can be ordered without a cabinet. Robust-Aire systems with one, two, or three diffusers can be housed in our Post Mounted cabinet.
A remote manifold kit is now available as an option with any Robust-Aire diffused aeration system. These kits allow for remote placement of the compressor system away from the pond or lake and allows you to place the valve manifold at the water’s edge. This option is ideal for remote ponds where electricity isn’t near the pond.
Each compressor will deliver air to the water’s edge via a customer provided 3/4″ PVC pipe to the valve box. Two compressor systems will require two 3/4″ PVC lines and two valve boxes. The RM kits include the valves, valve box(es), and fittings.
DP (Deep Water) and XL Robust-Aire Systems
The DP and XL systems are designed for deep ponds and lakes or applications where more water turnover per diffuser head is desired. The DP systems use the 1/2HP Teich-Aire compressor (KM-120) to deliver 2 CFM per diffuser head. The XL systems use the Teich-Aire 3/4HP compressor to deliver between 2.5 and 3.2 CFM per diffuser head.
In applications with significant water depths and regular shapes, more turnover per diffuser head may be a good choice. In these applications, fewer diffuser heads in the design can help save on equipment and installation costs.
Custom Design Assistance
Is your situation unique? With combinations of systems, we can provide a design for almost any lake. Custom design assistance is available including a system layout on an aerial map of your pond or lake.
