The Flygt Jet mixer is the union of two ITT innovations: Flygt N-technology and a unique ejector system. The JT4700 series is available in five different models for 50Hz, and four different models for 60Hz. It is an ideal choice where an on-the-ground, dry-installed mixing solution is preferred. Typical applications include retention basins; primary, waste-activated, and digested sludge tanks; and digesters.
