The Kasco RobustAire™ RA2 Diffused Aeration System provides a compact, effective solution for improving pond water quality through bottom-up aeration. A shore-mounted compressor delivers air through self-weighted lines to a diffuser positioned on the pond bottom.

Kasco RobustAire™ Diffused Aeration systems add beneficial water mixing and movement from the bottom up to improve water quality. Using a shore-mounted compressor, air is pushed through self-weighted lines to a diffuser on the bottom of a pond. 

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. 

RA2 System Features: 

• Includes 2 dual-loop diffuser assemblies, 1 compressor, small cabinet, and 200ft. 3/8" SureSink Weighted Tubing
• Cabinet can be mounted on the ground or on a vertical structure using the optional mounting bracket
• Ideal for small to mid-size ponds and lakes
