EDI’s MaxAir diffuser provides broad-band coarse-bubble aeration for maximum mixing efficiency. The unit is available in a 24-in. standard length, which provides a full 48-in. air release perimeter. Air release uniformity and mixing efficiency feature multilevel air metering orifice design, which provides full utilization over the entire operating range of the unit. MaxAir diffusers are ideal for demanding aeration and mixing applications, including flow equalization, channel aeration, aerobic digesters, industrial and mixing and scouring applications, such as RBC, MBR, IFAS and MBBR. Air distribution is achieved with fixed orifices positioned on three levels. As the airflow to the diffuser increases, the number of active orifices increases.
