Numerous aerator comparison tests prove that paddle wheel aerators have the highest oxygen input per kWh. The easy to understand reason for this is that paddle wheel aerators create a directional flow and distribute the enriched water in the water. The re-aeration of just aerated pond water, as is inevitable with some other types of aerators, is excluded. Paddle wheel aerators of the type PWA are used tens of thousands of times in fish farms and shrimp farms worldwide. In Europe, these devices are mostly used in fish farms and larger bodies of water (lakes, ponds).

Advantages:
- effective oxygen enrichment (O2)- degassing (CO2) with high fish stock
- current generation and distribution of enriched water in the water
- unclogable
- excellent price/performance ratio
- maintenance and repair (if necessary) on site
- very long service life (10 years in continuous operation and longer have been reported)

Due to the intensive flow generation, these devices are only conditionally suitable for small or medium-sized ponds. Even for the smallest devices with 0.49 kW (P2), the body of water should not be smaller than 500 m². If the waters are too small or too shallow, there is a risk of embankment flushing and sludge swirling. The devices are only conditionally suitable for winter.

The delivery takes place as a kit with assembly instructions. Please note that devices with three-phase motors must be commissioned by a specialist. It is strongly recommended to operate the device exclusively in conjunction
with an appropriate motor guard. Please note that if the device is operated without a motor-protective circuit-breaker, the warranty for the motor expires.
