Designed for larger pond aeration needs, the Kasco RobustAire™ RA3 Diffused Aeration System delivers efficient bottom-up water movement to improve overall water quality. Using a shore-mounted compressor, air is pushed through self-weighted lines to a diffuser located 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. 

RA3 System Features: 

• Includes 3 dual-loop diffuser assemblies, 1 compressor, small cabinet, and 300ft. 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
