Miaode Company has a history of more than 60 years since its establishment in 1951. The brand CONVUM is a word formed by taking part of the English words "Compressor" and "Vacuum". It fully demonstrates the principle of CONVUM using compressed air from a compressor to generate vacuum. After years of research and development, Miaode officially began producing and selling jet vacuum generators (CV series) in 1972. It is a pioneer in the history of jet vacuum generators. Its products are not only well received in Japan and have made certain contributions to automation, but also continue to expand its sales scope overseas. Currently in the industry, everyone directly calls the jet generator CONVUM, which fully demonstrates the popularity of Miaode-made generators in this field.
