About Nitto Kohki

For over three decades, Nitto Kohki U.S.A., Inc. (formerly Medo USA, Inc.) has been designing, developing, engineering, and continuously improving high quality air compressors and vacuum pumps for challenging applications like medical devices, laboratory equipment, and applied robotics. The result is an intelligent package that runs quieter, consumes less energy, and lasts longer than comparable equipment for these applications.

Nitto Kohki’s unique linear free piston design has one moving part per piston– one. This enables Nitto Kohki pumps to be smaller and lighter than conventional aerators, allowing designers greater flexibility in system design. The compact integrated design is also self-cooling, free of lubrication, and self-adjusting for pressure spikes– automatically adjusting power consumption and guarding against potential temperature overloads.

Based outside of Chicago, with corporate headquarters in Tokyo, Japan, we are a global manufacturing organization committed to assessing your application from an engineering perspective – so we can fully understand your challenges, and so we can recommend the most appropriate product to meet them.
