Kasco RobustAire Diffused Aeration
RobustAire™ Diffused Aeration
Kasco RobustAire™ Diffused Aeration systems add beneficial water mixing and movement from the bottom up to prevent weed overgrowth, algae, fish kills, and other issues. Using a shore-mounted compressor, air is pushed through self-weighted lines to a diffuser on the bottom of a pond, lake, or tank allowing water to be thoroughly mixed helping to prevent the most common water quality issues.
Newly designed Small Cabinets are now available in addition to our Medium and Large Cabinets, completing our offering of RobustAire systems with AireGuard Cabinet Technology. Utilizing this new approach to airflow, compressor cabinets are kept cooler and cleaner.
Warranty periods:
- Diffuser: Lifetime
- Cabinet: Lifetime
- Tubing: 15 years
- Compressor Motor: 3 years
- Compressor Piston Cups & Cylinders: 2 years

Description
AireGuard Cabinet Technology
Kasco patented AireGuard Cabinet Technology tackles the biggest stressors on compressor operation: heat and dust. With this innovative design, air is immediately passed through an external filtration layer that removes excess dust and debris. Powerful fans then pull this clean air through the compressor, instead of across it, allowing the compressor to stay much cooler and operate at extreme efficiency. The dual-action filtering and air movement acts as a safeguard for the compressor motor and entire system, allowing RobustAire to provide a reliable source of mixing and movement to the water.
This technology is offered in Kasco Small (NEW), Medium and Large Cabinets. These cabinets feature a sleek new look, external maintenance indicators, easy-to-remove panels for scheduled maintenance, quiet operation, and a paint color that seamlessly blends with the environment.
