Evolution Aqua Airtech 150 Air Pump

Maximum Pond Aeration for Large and Heavily Stocked Koi Systems

The Evolution Aqua Airtech 150 Air Pump is the highest capacity model in the Airtech range, delivering up to 150 litres per minute of airflow for demanding pond installations. It is specifically designed for large koi ponds, heavily stocked systems and intensive biological filtration setups. As a result, it provides the oxygen required to maintain stable water quality and healthy fish.

As koi biomass increases, oxygen demand rises sharply. Therefore, larger systems require powerful and consistent aeration to maintain aerobic bacterial activity inside biofilters. The Airtech 150 delivers exceptional airflow at surface level. In addition, it maintains approximately 130 litres per minute at 1 metre depth and around 119 litres per minute at 2 metres.

Consequently, this performance makes it ideal for deeper ponds, aerated bottom drains and large moving bed chambers. Furthermore, strong airflow retention at depth ensures reliable oxygen delivery even under pressure.

Because nitrifying bacteria rely on oxygen rich conditions, this pump improves ammonia and nitrite conversion efficiency. Moreover, higher dissolved oxygen levels reduce fish stress during warmer months and periods of heavy feeding. As a result, water remains clearer and filtration systems operate more efficiently.

The Airtech 150 is built for continuous duty operation. Its weather resistant aluminium housing protects internal components from outdoor conditions. At the same time, the integrated thermal protection device prevents overheating and safeguards long term reliability.

Despite its high output capacity, the pump operates quietly, maintaining a noise rating below 50 to 53 dBA. Additionally, with controlled power consumption of approximately 106 watts, it balances performance with efficiency.

Overall, the Evolution Aqua Airtech 150 is engineered for serious koi pond systems that demand maximum oxygenation and dependable long term operation.
