Coarse Bubble Aeration


MaxAir coarse bubble diffuser offers proven design and is ideal for both mixing and aeration applications.

EDI MaxAir™ diffuser provides broad band, coarse bubble aeration for maximum mixing efficiency. The unit is available in 24-inch standard length. The 24-inch diffuser unit provides a full 48-inch air release perimeter. Air release uniformity and mixing efficiency features multi-level air metering orifice design. This provides full utilization over the entire operating range of the unit.
MaxAir diffusers are ideal for the most demanding aeration and mixing applications, including flow equalization, channel aeration, aerobic digesters, industrial, and mixing and scouring applications, including RBC, MBR, IFAS, and MBBR.
