<h1 style="font-family:lydian;text-align:center;color:blue;font-size:35px;">Airmaster for Koi & Garden Ponds</h1>
Airmaster is a brilliantly simple patented design created by  a koi keeper to put oxygen into the water. It does this more efficiently and cost effectively than any other device on the market It can be easily fitted to pond systems. It is powered by the pond's circulation and because it has extremely low backpressure its running costs are negligible

HOW IT WORKS
Powered by the pond circulation and designed for a flow range of 500 to 4000 gallons per hour Airmaster's patented technology draws air into the water as it returns to the pond. The unique mechanism delivers air through tiny holes transferring oxygen to water more efficiently than any other method. The combination of microbubbles and designed turbulence ensures that the water leaving the Airmaster tube is oxygen enriched. Its fluid dynamic designed aquafoil creates negligible backpressure on the pump keeping running costs extremely low and making the Airmaster very competitive to other methods of aeration

A LIFE LINE FOR YOUR FISH
Your fish need oxygen to survive and the only source is dissolved within the structure of the water and it is strictly limited. Competition for oxygen from bacteria, plants,biological waste and decomposing vegetation, all consume oxygen and some of these are more efficient at extracting it than fish.Airmaster can maintain maximum oxygen levels to compensate for this variable demand.

AIRMASTER WMS
The Airmaster WMS has been developed so that larger bodies of water can be circulated and oxygenated  efficiently and at minimal energy cost
