Air technology applications covering compressed air and vacuum take a significant share of the electrical consumption. Air compressors, vacuum pumps and blowers typically are running for a significant amount of hours per day. Since these applications are subject to variable demands make these applications suitable for high efficiency speed controlled motors controlled with drives.
Air compressors convert power, usually from electric motors into a kinetic energy by compressing and pressurising air and on commend can be released in quick burst. Constant torque application with long service renders this application a target for efficiency improvement and energy consumption reduction.
