AirOxi partners with Redox of Norway to provide oxygen concentrators and EPDM diffusers for aquaculture. Redox oxygen concentrators are compact, produce 93% pure oxygen, require low maintenance, and are used by reputable aquaculture companies. They are portable, designed for industrial use, and can provide sufficient aeration for 3 tons of fish biomass while using little power. Although the initial cost is high, it is offset by energy efficiency, high oxygen levels increasing fish production, and almost zero maintenance.
