We are offering the true value of pneumatic equipment. Inquiries to this Company Japanese

Electric Machinery and Instruments Manufacturing

There are three categories of products we deal with, including pneumatic actuators and control equipment, compressed air dehumidifier and pneumatic appliances. Various kinds of pneumatic drive equipment / control equipment are manufactured according to the application.
Three kinds of compressed air dehumidifier are available, refrigeration type, intake type, membrane type. We utilize refrigeration technology to manufacture its applied machines and so on. For pneumatic appliances, we are producing nitrogen gas generators that produce highly pure nitrogen gas by removing oxygen molecules in compressed air, and cold air generators that apply the principles of Voltics. We manufacture various products according to customer's needs.
・ Development of pneumatic equipment
・ Refrigeration technology
Our products are sold to various industries such as machine tool trading company, catalog mail order, compressor manufacturer, shipbuilding industry, weak electric manufacturer, vacuum industry, etc. Pneumatic actuators and control devices are purchased by various users by machine tool trading companies and catalog mail order. Also, our dehumidifier has gained considerable recognition in compressor manufacturers and shipbuilding industry.
Our activities are not merely "making things" and "sales activities" of pneumatic equipment.
We will consciously and sensitively adapt to the opportunity of expanding the business area, aim to be a company that all employees and their families are proud of contributing to society, being trusted by customers with the motto:
・ Accurately grasp the changes in the environment and situation inside and outside
・ Have a creative and flexible idea regardless of success experience
