Blue Diamond 12 inch round disc air diffuser is a commercial fine-bubble aeration component for ponds, hydroponic reservoirs, and wastewater systems. Its EPDM and silicone membrane produces 1 to 3 mm bubbles to support efficient oxygen transfer with low backpressure. The self-sealing membrane helps reduce sludge and water backflow when airflow stops. A 3/4 inch male threaded inlet supports up to 60 LPM and fits compatible Blue Diamond DS1, DS2, and DS4 diffuser stations. Built for long-term use.
