Variable Speed Drive Air Compressor Technology

Variable Speed Drive Air Compressor Technology

The Ohio-based company Eaton Compressor & Fabrication, Inc., is responsible for the manufacture and supply of quality rotary air compressors, full-sized and portable air compression devices, and air tools to organizations in the United States, Canada, Mexico, and further abroad. Eaton Compressor & Fabrication, Inc., is led by chief executive officer Matt Cain and specializes in the production of energy-efficient air compression solutions.

Variable Speed Drive Air Compressor Technology

Variable speed air compressor drives reduce energy consumption by up to 30 percent in comparison to a centrifugal compressor application. Such a significant energy-saving measure occurs as the variable speed AC drive controls the unit’s speed, ensuring that the motor does not operate at a faster speed than necessary while compressing air into its optimal pressure. More traditional methods of air compression operate at a fixed speed until the correct pressure is reached and then stop the motor.

Variable Speed Drive Air Compressor Technology

Variable frequency technology allows for control of the unit’s speedat the onset via the electrical current and voltage supply. Incoming electrical power is converted from AC to DC and then into a quasi-sinusoidal AC supply. This process is controlled by an inverter switching circuit. Although the technology is more expensive than its traditional fixed speed counterpart, it reduces both electricity costs and the incidence of power surges caused by starting and re-starting motors.
