Nitto Kohki USA


Nitto Kohki, U.S.A., Inc. leads through exceptional product design and execution, with pumps that meet the rigorous demands of today’s medical device industry.

Nitto Kohki’s pumps feature a unique, patent-awarded linear-motor-driven free piston system that is globally proven in the medical device, instrumentation, and other critical industries. This unique design theory eliminates the wear components typically found in conventional air compressors and vacuum pumps, such as crank shafts, connecting rods and ball bearings. The only moving part is the piston! Also eliminated is the need for any lubrication. Fewer parts translate into fewer problems.


  • Exceptionally reliable performance for critical applications
  • World class manufacturing expertise ensures consistent product quality
  • Clean, simple design maximizes performance, minimizes maintenance — adding value over the integrated product lifecycle.

Nitto Kohki, U.S.A., Inc. designs, develops, engineers, and continuously improves high quality air compressors and vacuum pumps for applications like medical devices, laboratory equipment, applied robotics and environmental sensing equipment.

Nitto Kohki, U.S.A’s unique linear free piston design has one moving part per pump— the piston. The result is a pump with exceptionally reliable performance in tough medical applications. The linear free piston concept enables Nitto Kohki, U.S.A’s pumps to be smaller and lighter than conventional aerators, allowing designers greater flexibility in system design.
