Air Diffuser Manifold – Alumina Airstones

Maximize aeration efficiency with Air Diffuser Manifolds featuring high-performance alumina air stones, available in 2, 4, and 6 airstone configurations to suit a variety of pond and lake applications. Designed for superior oxygen transfer, these systems produce finer bubbles than standard membrane diffusers, improving water circulation and overall aquatic health. Each manifold includes a built-in check valve to prevent water backflow, a durable polyethylene underlay to keep diffusers from settling into sediment and reduce erosion, and 6″ alumina air stones for consistent performance. With included strain relief and fittings compatible with 3/8″, 1/2″, or 5/8″ ID tubing (model dependent), these manifolds offer flexible installation and reliable operation for efficient, long-term aeration.
