KAESER

Kaeser:

Kaeser Kompressoren SE is a prominent German manufacturer specializing in compressed air systems and services. Established in 1919 by Carl Kaeser Sr. in Coburg, Germany, the company began as a machine workshop producing car and engine parts. Post-World War II, Kaeser shifted focus to compressed air technology, launching its first reciprocating compressor in 1948. In 1973, under the leadership of Carl Kaeser Jr., the company developed its first rotary screw compressor featuring the energy-efficient "Sigma Profile" rotor design.
