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.

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.
