Sweetwater® Micro Bubble Oxygen Diffusers
These ultra-fine pore diffusers are ideal for pure gas applications (oxygen, carbon dioxide), high-density hauling, holding/growout tanks and emergency aeration. Choose from aluminum or nylon 6/glass composite (plastic) base. Optimal running pressure is 20 to 30 psi. Max 50 psi
Aluminum models are best for long-term, heavy-duty use.
Plastic models are tested at -20ºC to ensure performance and integrity. They also give you the convenience of two 1/4" barb positions to choose from, and their preinstalled check valve prevents damage. Dual barb position feature only available with plastic base diffusers.
