Secret To Pond Excellence

The Kasco Robust Aire aerator kit was designed specifically to work in very deep ponds. So if you have a reservoir that’s between 8 to 50 feet deep, this model will be perfect if you want to keep the water oxidized and healthy. It will eliminate bad odors, and reduce the nutrients and mucks, making it better for fish, plants, and people around the pond.

It’s one of the most efficient diffusers on the market that is able to create a fine air bubble almost without any pressure; it operates on large surfaces with very low power consumption. It can be filled with any kind of weighted substrate and, thanks to its raised design, it can perform as expected above the bottom. The tubing won’t get detached during installation or regular maintenance, and a check valve with Viton seals will keep it safe from water, even when it’s not operating.


There’s no electricity in the water so it can be safely installed in a reservoir destined for swimming. Everything is hidden, hence it won’t disturb your view. Plus, its rocking piston compressor doesn’t require as much maintenance as other compressors. Most of the work can be conducted onshore and even remotely.


It’s available either with no cabinet, with large base mount cabinet or post mounted cabinet. To explore your options, and choose the right one for your needs and expectations, contact us to get professional advice.

Quality that works!

Well made. Good instructions. Amazing oxygen generator. A key ingredient to restoring a pond I used to swim in as a kid, but like many bodies of water, suffers from nutrient loading. Nothing short of miraculous.

Excellent product! Very easy install!

This aerator came in a few days and is very nice quality. Installation was a breeze. Working great and definately got my pond moving water off the bottom.

Kasco Robust Aeration System Works Great

Bought this system for my 1/3 acre pond. Previously had used my windmill but was becoming expensive and time consuming to maintain. System came in excellent packaging and easy to follow instructions. Placed in my pond within an hour and has been working great. Seems to be turning over much more water than my windmill system did. Purchased optional case with fan that hangs on a post by my pond. Most work involved was to run electric out to the post. Great purchase - very happy.
