WaterBug B4 DiffuserProduct Code: WBB4
This diffuser features a unique micro-porous membrane that keeps fine bubbles from coalescing into bigger bubbles. This feature greatly increases the amount of water that these diffusers can move, which means much better aeration.
Airflow rates of 0.5 to 1.5 CFM are recommended for the WBB4 Diffuser, but they can handle more than 3 times that much. We recommend using a check valve (not included Item # CV-MAT38, CV-MAT12 or CV-MAT58 for the different sizes of airline) to prevent lines from filling with water if used for winter aeration.
