Air Energy Business

In our air energy business, we provide comprehensive air management services that supply “the energy that is essential to our society” in the form of pneumatic equipment, expanders, and vacuum equipment in a stable and efficient manner. We will contribute to a prosperous society by pursuing oil-free technology that compresses gases, mainly air, as well as energy-saving features, thereby providing products that meet the needs of our customers around the world.

Our Strengths in the Air Energy Business

We contribute to the creation of a prosperous society through our core technology that compresses gases, mainly air, without the use of oil.

  • Oil-free compressors that supply clean, compressed air without using lubricating oil
  • Technology that developed and commercialized the world’s first air-cooled, oil-free scroll compressors that are quiet with excellent energy-saving features
  • Industry-leading productivity, with combined use of automated assembly lines
  • Uniform product quality achieved through production in a work environment that combines people and automation
  • Reliability and stability backed by the second largest market share (in-house estimate) in the domestic small-sized compressor market
  • A supply system that is capable of same-day shipping for domestic orders of small-sized compressors
  • A global manufacturing and sales network
