Description
Robust-Aire Difused Aeration Systems
Engineered to be the best in the industry.
NEW Kasco’s Robust-Aire™ systems are NOW 34% quieter and easier to maintain. Newly redesigned, these systems feature a significant reduction in sound (patent pending), larger air filters on 1/4HP and 1/2HP systems for less frequent cleaning, and a visual maintenance indicator to alert when maintenance is needed.

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.
All Robust-Aire™ diffused aeration systems are available with an optional remote manifold allowing the compressor to be installed up to a mile away from the water’s edge.

FAQ
FAQs
Diffused aeration releases air at the pond bottom, gently lifting low-oxygen water upward and allowing it to mix with oxygen-rich surface water, which reduces harmful stratification. This slow, continuous circulation spreads dissolved oxygen more evenly throughout the water column, improving overall water quality and supporting fish health.
Each diffuser can effectively aerate about 1 to 1.5 acres of water up to 50 feet deep. Larger systems with multiple diffusers are needed for larger or irregularly shaped ponds.
Yes. The compressor is placed onshore and can be placed up to one mile away from the shoreline using a manifold and trenching pvc tubing back to the compressor.
The compressor is housed in a weatherproof, sound-reducing cabinet. It operates quietly and is suitable for use near homes and cabins
Yes. Robust-Aire is ideal for winter use. It helps keep a hole open in the ice, preventing fish kills by maintaining oxygen levels under the surface.
Not if positioned correctly. The system is engineered to gently circulate upward through your entire water column.
No. It’s designed to run 24/7 for maximum benefit. You can add a timer if desired, but continuous operation supports consistent water quality.
Minimal. Clean or replace the air filter on the compressor annually and check diffusers if you notice reduced bubble output. The sure-sink tubing boasts a 15-year warranty and the diffuser boasts a lifetime warranty.
Yes. The weighted tubing allows you to reposition diffusers if needed, though it’s best to determine optimal placement ahead of time for consistent circulation.
Yes. The diffusers help keep algae under control by moving water and adding oxygen throughout the pond. When the water is always circulating, there are fewer still or stagnant areas where algae can grow. Circulation also keeps nutrients from sitting at the surface, where sunlight helps algae spread quickly.
