Surface Aerators for Ponds and Lakes

At Sterner we offer 2 key types of aerators, both ideally suited to lakes; Floating Aerators and Paddle Wheel Aerators

Floating Aerators

Low profile floating aerators are a solution for lakes and ponds under two metres deep. Producing an attractive, bubbling cauldron effect, floating aerators are ideal for commercial and private applications alike.

Paddle Wheel Aerators

A great 'emergency' solution to your aeration needs. Paddle wheel aerators are quick and easy to install and can easily be moved around to different sites. They are particularly good at providing aeration to fish stock during low Dissolved Oxygen events such as algal blooms or low atmospheric pressure.


  • PWA paddle wheel aerator 0.75 kW, 230V, Single Phase Paddlewheel Aquacultur Default Title

    Aquacultur PWA paddle wheel aerator 0.75 kW, 230V, Single Phase

    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 conjunctionwith an appropriate motor guard. Please note that if the device is operated without a motor-protective circuit-breaker, the warranty for the motor expires.PWA paddle wheel aeratorDelivery as kit with assembly instructions, without cable,without motor protection plugNumber of paddle wheels: 2Motor rated power P2: 0.75 kW Power consumption P1: 0.87 kW /5.5 Aelectr.

  • Linn Aqua-Hobby Floating Aerator Pond Aerator Linn 9.5mm (Standard)

    Linn Linn Aqua-Hobby Floating Aerator

    The range of Hobby aerators is used both in the hobby area and for small to medium-sized ponds in fish farming. This aerator, developed for reliable continuous operation, has a very good price / performance ratio and is in use a thousand times. The encapsulated motor is cooled by the pumped water and does not make any running noises - only the rushing water can be heard Technical Data- Motor nominal power P2: 150 watt - Connection: 230V / 50Hz-1ph. - Throwing circle: max. Ø200 cm - Spacing of the sieve basket: 9.5 mm - Weight: 15.0 kg DescriptionThe range of Hobby aerators is used both in the hobby area and for small to medium-sized ponds in fish farming. This aerator, developed for reliable continuous operation, has a very good price / performance ratio and is in use a thousand times. The encapsulated motor is cooled by the pumped water and does not make any running noises - only the rushing water can be heard. The large stainless steel protective cage prevents fish or branches from getting into the propeller area. Despite the large area of ​​the basket, it may be necessary to clean the basket from time to time when mowing or when there is an excessive fall of leaves in autumn. You can achieve the highest oxygen input with these devices in water with a light flow. If you do not want to operate the aerator in continuous operation, it is possible to set the desired ventilation times during the day or night using a commercially available timer (not included). In summer, especially in bodies of water with intensive vegetation, it can make sense to start ventilation during the night, see data sheet. It is supplied as a ready-to-use device with a 15 m cable and plug. We recommend this aerator for ponds with an area of ​​max. 150 m².
