Revitalize Your Water With The Kasco Robust-Aire Diffused Aeration System

Immerse yourself in the quiet power of Kasco's Robust-Aire™ system, delivering exceptional aeration benefits in depths surpassing 8 feet. Operating silently, a shoreline-based compressor propels air through self-weighted lines to a dual-loop diffuser positioned at the water's base in ponds, lakes, or tanks. The diffuser releases a continuous stream of micro-bubbles, lifting significant water volumes to the surface. This dynamic mixing process not only boosts oxygen transfer but also addresses thermal and chemical stratification, enriching water quality and expanding fish habitat, unlocking a myriad of benefits.

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.
