Description
Kasco Robust-Aire System 2 (without Cabinet)
Efficient Deep-Water Aeration for Ponds and Lakes
The Kasco Robust-Aire System 2 is engineered to provide superior aeration in water depths ranging from 8 feet to 50 feet. This specific package is designed for installations where a protective cabinet is not required—ideal for mounting inside existing sheds, barns, or boathouses. By pumping compressed air from a shore-mounted compressor to diffusers on the pond floor, the system creates a continuous "lifting" action that eliminates thermal stratification and boosts dissolved oxygen levels.
Robust-Aire™ systems are widely recognized as the most efficient deep-water aeration solution on the market, moving more water with less energy than competing brands.
Key Features:
-
No Cabinet Design: Includes all essential aeration components without the extra cost of a metal or plastic enclosure. Perfect for indoor or sheltered installations.
-
Dual Diffuser System: Includes two (2) Robust-Aire™ diffusers, which utilize a proprietary design to prevent clogging and provide fine-bubble aeration for maximum oxygen transfer.
-
High-Performance Compressor: Features a reliable 1/4 HP or 1/2 HP rocking piston compressor (based on configuration) designed for continuous, year-round operation.
-
Depth & Coverage: Effectively aerates ponds up to 3 acres (depending on depth and shape). Most effective at depths over 8 feet.
-
No Electricity in Water: All power remains on shore. Only air is pumped through the weighted tubing, ensuring a safe environment for swimming and recreation.
-
Improved Water Health: Reduces muck and organic solids, eliminates foul odors, and prevents winter fish kills by keeping a portion of the surface ice-free.

The Robust-Aire Advantage Kasco’s Robust-Aire diffusers are designed to produce a "column" of air bubbles that is significantly more effective at inducing water movement than standard aeration stones. As the bubbles rise, they pull oxygen-depleted water from the bottom to the surface, where it can release toxic gases and absorb atmospheric oxygen. This process—known as "induced circulation"—is essential for maintaining a healthy ecosystem in deeper lakes and ponds.
Installation Note: Because this system does not include a cabinet, the compressor should be placed in a clean, dry, and well-ventilated area to prevent overheating and ensure a long service life. If outdoor placement is required, please see our Robust-Aire systems with Post-Mount or Base-Mount cabinets.
