Quick Sink Self-Weighted Diffuser Assembly – Double Diffuser

The QS2 Quick Sink Self‑Weighted Membrane Air Diffuser Assembly is engineered to deliver efficient aeration with a durable, low‑maintenance design. Its dual fine‑bubble membrane diffusers provide strong oxygen transfer and consistent lift, helping improve water quality in ponds and freshwater systems. The self‑weighted, powder‑coated steel base keeps the diffuser securely positioned on the bottom without requiring additional weights. Built‑in strain‑relief hardware ensures a secure connection, while the unique barbed fittings with integrated check valves help prevent water from entering the airline. The diffuser accepts multiple tubing sizes and operates with low head pressure, making it suitable for a wide range of aeration setups. Designed for long‑term reliability, this assembly supports airflow from 1.6 to 6 cfm and includes a 3/4″ MPT inlet for straightforward installation.
