Our new diffuser is made up of a porous membrane for specialized applications in aquaculture where there is a need for a white or translucent product for easy visibility, along with a very smooth surface for easy as well as convenient cleaning. This new AirOxi Smooth Plastic Diffuser gives a very little backpressure, thereby making sure that the product works very well with almost all types of blowers, air pumps, oxygen cylinders, and generators.
