Kasco Robust-Aire 5: 1/4 & 1/2 HP 120V

Robust-Aire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake, or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen transfer as well as beneficial water movement and mixing. OVERVIEW The system includes 2 rocking piston compressors (a 1/4 and a 1/2 HP), 5 diffusers, and a base mount cabinet.  The option of a Remote Manifold is available.  Weighted air tubing is sold separately on systems with 4 or more diffusers.
