In 1959, David Mosimann, an inventive precision mechanic with a very entrepreneurial mindset, decided to set up his own business by founding Bien-Air. The company expanded continuously, and in 2001 it created two spin-off companies, Bien-Air Dental and Bien-Air Surgery, with a view to providing perfectly adapted specialist services. Well established in Switzerland's "Watch Valley", with its cultural heritage of research, high precision and practical ingenuity, the company creates and manufacturers all its products locally. Today, Bien-Air has several subsidiaries worldwide which distribute its products and provide fast, efficient after sales service. The requirements based on everyday practice served as a reference for the development of various products in the sectors of micromotors and precision instruments, with a view to establishing more reliable and simpler clinical treatment and laboratory procedures. Over the years, Bien-Air has evolved from being a manufacturer of Swiss made instruments and devices to a minimum for performing a maximum of operations. This strategy has enabled Bien-Air to continuously improve the efficiency of its instruments, increase capacity of its electronic controls and develop new systems.
