Blue Diamond 20 Inch Fine Bubble Tube Air Diffuser 500mm EPDM Membrane with 3/4 Inch Threaded Inlet


SKU: 20" TUBE

Blue Diamond 20 inch tube diffuser is a commercial fine-bubble aeration component for tanks, wastewater grids, ponds, and lake systems. Its EPDM and silicone membrane features thousands of micro-perforations that produce 1 to 3 mm bubbles for efficient oxygen transfer. The self-sealing membrane helps reduce sludge, debris, and water backflow when airflow stops. A durable PVC core with a 3/4 inch male threaded or 19 mm barbed connection supports manifold installations and long-term submerged use.
