SHARE

Trouble-free maintenance makes the Sanitaire single drop diffuser perfectly suited for applications where dewatering isn’t possible, such as aerated channels or digesters. Its innovative dual shear plate design and multiple air release slots assure optimized efficiency of oxygen transfer, and an optional clean-out port allows for manual cleaning without draining basins or channels. The injection-molded plastic diffuser body is available in 1-inch (2.5 cm) or 2-inch (5 cm) sizes.
