Oase AquaAir Eco 250 Floating Lake Aerator

Oase AquaAir Eco 250 Floating Lake Aerator

High-Performance Floating Aeration for Lakes and Large Ponds up to 250,000 Litres

The Oase AquaAir Eco 250 is a powerful floating lake aerator designed to oxygenate large ponds, estate lakes and extensive water bodies up to 250,000 litres. Combining a high-performance 26,000 litres per hour pump with a venturi air injection system, it delivers up to 8,500 litres of air per hour while creating strong circulation currents throughout the entire water column.

Unlike standard air pumps that rely purely on diffused air stones, the AquaAir Eco 250 actively moves large volumes of water. As a result, it improves oxygen distribution, reduces stagnant zones and revitalises deeper areas where silt and nutrient build-up typically accumulate.

Because oxygen plays a vital role in biological rejuvenation, this floating aerator helps break down organic waste, reduce sludge layers and limit algae growth. Therefore, it is particularly suitable for fisheries, ornamental lakes, estate ponds and commercial water features where water movement and oxygen stability are essential.

The floating design allows easy repositioning to problem areas, while the adjustable injector nozzle enables effective aeration in both shallow margins and deeper zones up to 4 metres. In addition, the powerful water turnover helps prevent ice formation during winter by maintaining surface movement.

The AquaAir Eco 250 also features EGC connectivity, meaning it can be controlled via the Oase InScenio FM Master EGC Cloud system for remote management and monitoring.

Aeration setup notes

Oase AquaAir Eco 250 Floating Lake Aerator should be chosen as part of the complete air system, not just by litres per minute. Airline length, airline bore, diffuser depth, manifold taps and back pressure all affect the real airflow that reaches the pond or filter.

• Use suitable airline size for the pump output and distance involved.
• Keep air pumps dry, ventilated and protected from flooding.
• Spread airflow across multiple diffusers on larger ponds where possible.
• Check diaphragms, filters and diffusers during routine servicing.

Before you order

Before ordering Oase AquaAir Eco 250 Floating Lake Aerator, check the product dimensions, connection size, cable length, installation space and any supporting equipment needed to make it work correctly. This helps avoid compatibility issues and makes the final pond system easier to maintain.

Maintenance and compatibility checks

It is worth checking the supporting parts at the same time as the main product. Hose size, pressure pipe, valves, unions, UV units, filter inlets, air manifolds, spares and cleaning access can all affect how well the final system works. A correctly matched installation usually performs better and is easier to maintain than one built from parts chosen separately.

Final setup check

Before ordering Oase AquaAir Eco 250 Floating Lake Aerator, check the expected diffuser depth, airline run and number of outlets required. The same air pump can perform very differently depending on back pressure, diffuser condition and manifold layout. Keep pumps dry, ventilated and accessible so diaphragms and filters can be serviced before airflow drops.
