Superior Aeration For Ponds Up To 16,000 Gallons
Circulates & oxygenates up to 16,000 gallons of water
Powerful yet efficient compressor uses as little as 17 watts
Airline, diffuser membranes and plate assemblies included
This is a great, all purpose small pond aeration kit. It includes a high efficiency pump with dual air controls, 50′ of 3/8″ weighted airline, 2 – 2 stick diffusers and fittings.
The suggested maximum operational depth for the diffusers is 4′. Going much beyond this will reduce the quality of the aeration and possibly the life of the compressor. In smaller ponds it’s certainly acceptable to place the diffusers around the pond (in shallower locations) rather than the middle, in order to aerate effectively.

FAQ
What is the maximum depth at which the diffusers can operate effectively?
The diffusers are recommended to operate at a maximum depth of 4 feet. Operating beyond this depth may reduce aeration quality and potentially shorten the compressor’s lifespan.
How many diffusers are included in the kit?
The kit includes two 2-stick diffusers.
Is the compressor energy efficient?
Yes, the compressor uses as little as 17 watts, making it energy efficient for long-term operation.

Installed the AIRMAX KOIAIR 2 in my 12,000-gallon pond last month. The aeration works well even on cloudy days. The diffusers are easy to place around the edges where water is shallower. No issues with noise or power usage so far. Works smoothly with the existing pond setup.

Good value for the capacity. The airline is long enough to reach the back of the pond. I placed the diffusers near the edges since the pond is deeper in the center. Aeration improved noticeably after a week of use.

The pump runs quietly and uses very little power. I noticed more fish activity and better water clarity after setting it up. The included fittings made installation simple. Would recommend for any small to medium pond.
