Kasco Marine RA2 Robust‑Aire Diffused Aeration System
This Kasco RA2 aeration system is a very good kit that has everything you need to aerate a pond from around 1 to 3 acres in size (depending on the depth).
Effective aeration can be achieved in 1 acre ponds 5 to 8 feet deep, 2 acre ponds 8 to 12 feet deep, and 3 acre ponds 12 to 16+ feet deep.

Mark's Take: I have always found the Kasco aerators to be some of the most efficient and reliable aeration systems around. The unique diffuser design provides a lot oxygenation and movement, or circulation, out of a small amount of air input. This often will let us use a smaller sized pump, and possibly a smaller number of diffusers compared to other good brands on the market...and in the end, this achieves what we want to see in the pond, while saving money on the aerator up front, and in operational costs over the long term.
The Teich-Aire compressor can work down to depths of 50'.
The 1/4 HP compressor draws 2.5 amps on a 115v set up and 1.2 amps on the optional 230v power supply (contact us if you require 230v).
Air output is 3.2 CFM's at 10psi.
This system includes:
The Robust-Aire RA2 system:
• One KM-60 model ¼ HP Teich-Aire compressor. Cabinet is optional, but weather protection for the pump is required.
• Dual port aluminum manifold with valves
• Two, 100 foot rolls of 3/8 inch Sure Sink weighted tubing. Need more airline? You can find that here!
• Two Robust Aire diffuser assemblies
OPTIONAL PACKAGES
The standard RA2 package comes with a fully weather proof, lockable, powder coated steel, ground based cabinet, cooling fan, and accessories to provide full protection for the compressor system. A pole mounted cabinet option is also available and can be mounted on a 4x4 post. And finally, if you have a building or structure near the pond already you may choose to get the RA2 system without any cabinet and it will work fine as long as you keep the compressor dry and well ventilated for cooling.
ADDITIONAL FEATURES
Robust-Aire Diffusers
Kasco Aeration uses superior diffuser materials and design. Robust-Aire has been tested alongside 6 other leading designs by 4 other manufacturers. Between 10 and 44% more
water flow was induced with the same volume of air injected into the water column. The system simply creates more water flow to aerate the pond with the same amount of air and energy making it the most efficient on the market.
This is the result of an efficient diffuser which allows air to escape at a very low pressure, to produce smaller bubbles with less friction loss. The bubbles are approximately 3mm in diameter. The U-shaped design and placement of the four diffusers enhances the upward flow of water. The diffuser material is durable and cleanable. While nothing
is maintenance free, seasonal cleaning of the diffusers in order to maintain efficiency is easy. The hydrophobic material partially repels growth films and can be cleaned with a rag or gloved hand.
