Gardner Denver Ultima Oil-free Air Compressor Enhances Operational Efficiencies

Ultima Compressor

Gardner Denver’s Ultima oil-free compressor sets a benchmark for performance and operational efficiencies and for meeting the highest possible air quality standards. When considering the available technologies, a major drawback to traditional two-stage oil-free compressors is the reliance on a gearbox. Not only do these consume large amounts of energy, but they also require increased oil volume to lubricate the gears. In contrast, Gardner Denver’s Ultima compressor has been engineered with two highly-efficient, permanent magnetic motors that replace the traditional gearbox design. These two, variable-speed motors are capable of achieving speeds of up to 22,000 RPM and efficiencies greater than 98%. The motors directly drive the airends without the need for a gearbox, thereby increasing efficiency.
