Use
The aerator Aqua Air 250 LM enriches the water with vital oxygen to decompose contaminants resulting from excessive
nutrients, such as ammonia/ammoniac or nitrite. Via a bypass (injector), the water flow at the pump outlet creates a vac-
uum. The air taken in at this point mixes with the outflowing pond water. When used in combination with the OASE prod-
ucts Bacto Plus LM and/or Ground Clear LM, the cleaning process is notably increased by the targeted colonisation of
micro-organisms requiring oxygen. Aqua Air 250 LM is recommended for a maximum water volume of 250 m³.
Intended use
The aerator AquaAir 250 LM, in the following text termed unit, may only be used to enrich normal pond water with air at
a water temperature of +4°C to + 35°C. Do not use the unit in swimming ponds.
Use other than that intended
Danger to persons can emanate from this unit if it is not used in accordance with the intended use and in the case of
misuse. If used for purposes other than that intended, our warranty and operating permit will become null and void.
