Aeration of Water
OctoAir® Aeration Systems
OctoAir is a high-performance fine-bubble aeration system designed for improving water quality across lakes, reservoirs, rivers, estuaries and construction sites.

Value driven, the OctoAir 10® and OctoAir 60® range provides long term solutions to reduce operational costs and improve water quality, no matter the scale of project.
Built from marine-grade stainless steel with corrosion-resistant Bubble Tubing, OctoAir provides reliable circulation, oxygen transfer and mixing in both fresh and saline waters.
Exclusive to Frog Environmental in the UK, OctoAir is trusted for applications including:
- Aeration; protecting aquatic life and reducing nutrient spikes that drive algae blooms
- Mixing; preventing issues caused by stagnant water
- Circulation and upwelling; improving turnover in stratified waters
- Destratification; reducing negative summer impacts such as harmful algae blooms (HABs)
- De-icing; preventing freezing during winter months
- Nutrient reduction; proven to lower manganese and ammonia levels, improving water quality
