Kasco Robust-Aire RA1 PM Aerator

This Kasco model comes with 100 feet of Sure Sink 3/8” air tubing. A proven economical 1/3 Hp compressor delivers the system. Aeration dramatically improves environmental conditions in your pond and helps keep good water quality predictable. Beneficial bacteria reduce sludge and nutrients, and there are reduced incidences of undesirable algae and odors. Aeration allows your fish to thrive in an optimal environment and fish populations experience improved growth rates and vigor.

By using compressed air injected directly into the bottom of pond, a continuous flow of water is moved upward and thousands of gallons of water are mixed with little expended energy. A Robust-Aire™ energy efficient compressor injects air to the bottom of your pond with weighted, SureSink™ air line. The diffuser breaks up the air into micro bubbles which rise to the surface. The rising of the air bubbles creates current which transfers low-oxygen water to the surface, allows it to contact the atmosphere, and breathe. Temperature layers are disrupted and fish are able to inhabit the entire water column. Oxygen levels increase and harmful gases in the pond water are expelled.

We strongly recommend you order the cabinet model unless you have a shed or other protective housing that is ventilated to avoid over heating that could reduce the compressor life. The cabinet mount easily attached to a typical wood square post.
