The Electra Saver™ II G2 builds on the thousands of hours of reliability that were established by its predecessor. Founded on slow-speed, 1800 rpm design principles the new Electra Saver™ II G2 rotary screw compressors feature super-sized bearings and up to 40 percent larger airends than the competition. The larger airends, running at slower speeds, maximize efficiency and reduce wear and tear, while the permanent alignment of the airend and motor ensure maximum coupling and bearing life.
