The Kasco Marine RA1 diffused aerator will cover any pond up to about 1 to 1.5 acres depending on the depth. The compressor can work effectively down to 50' of depth.
Effective aeration can be achieved in 1/4 acre ponds 5 to 8 feet deep, 1/2 acre ponds 8 to 12 feet deep, and 1 to 2 acre ponds 12 to 16+ feet deep.
Contact us if you have questions about fitting the right aeration system for your pond.
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.
The Robust-Aire RA1 system: • One KM-60 model ¼ HP Teich-Aire compressor. Cabinet is optional (weather protection for the pump is required). • One, 100 foot roll of 3/8 inch Sure Sink weighted tubing. Need more airline? Get it here! • Robust Aire diffuser assembly
The standard RA1 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 RA1 system without any cabinet and it will work fine as long as you keep the compressor dry and well ventilated for cooling.
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.

After watching Mark’s YouTube videos I purchased the RA1 system for my 1/3 of an acre pond. I emailed Mark several times with question and he was very responsive. The install of the system was smooth. I am pleased with the aeration it provides. Well worth the money and effort.

This RA1 came highly recommended and I agree with that opinion. It was relatively easy to install and is running great. Pond's looking a bit better already.
