Osaka Vacuum was founded in 1950 in Naniwa, Osaka, by I. Kasaoka, an aircraft engineer, with the goal of perfecting the production of rotary vane mechanical pumps and vacuum coaters. By 1962, the Osaka and the Sakai facility of Osaka Vacuum were in full production of a wide variety of vacuum pumps, thin film deposition systems, and steam-jet ejectors. In 1970, in cooperation with the Physical & Chemical Institute of Japan, Osaka Vacuum successfully developed the first turbomolecular pump from Japan, which led to the opening of a new design and manufacturing facility in Hachioji. This design center was responsible for creation and introduction of the world's first compound turbomolecular pump in 1982 for wide range pumping; and the world's largest turbomolecular pump with 20,000 l/s pumping speed in 1990.
Today, Osaka Vacuum has three factories equipped with some of the most state-of-the-art machinery in Japan, covering more than 10,000 sq. meters in floor space. Osaka Vacuum now employs more than 300 people, mainly in R&D and manufacturing of vacuum equipment.
Sales and service worldwide are provided through a combination of Osaka Vacuum's direct divisions and independent representatives. The North America division, Osaka Vacuum U.S.A., Inc., located in Fremont CA, specializes in customizing applications specific to compound turbomolecular pump technology.
