There are five EcoGenTM standard frames ranging from 65 to 225 scfm in capacity (100 to 355 Nm3/hr.). Three different maximum outlet pressure levels are available – 15, 43, and 150 psig (1, 3, and 10 barg). When running at pressure below the models’ maximum, some power is saved. The higher the pressure, the higher the capital and energy requirement. See the brochure for more technical, features, and end use applications information.
