Air Compressors
Kaeser Screw Compressors

Kaeser Compressors, Inc. manufactures compressed air and vacuum products, including rotary screw compressors, oil-less reciprocating compressors, rotary lobe blowers, refrigerated and desiccant dryers, filters, condensate management systems and other related products. The company provides service, rentals, and consulting services. Kaeser Compressors, Inc. is a US affiliate of Kaeser Kompressoren headquartered in Coburg, Germany.


Carl Kaeser, Sr. founded the Kaeser organization as an engineering workshop that produced car and engine parts in 1919. Soon after, the factory was reconditioning engines, producing gears and building special purpose machines for the local glass industry. It wasn’t until the post-war need for compressed air in the rebuilding of Germany that the company began manufacturing and developing air compressors. The company grew rapidly after turning out its first reciprocating compressor in 1948, and by 1960 had outgrown its facility of 38 years and moved to a new location in Coburg, Germany.

Under the leadership of Carl Kaeser, Jr., Kaeser engineers developed a rotary screw compressor that featured the “Sigma Profile” airend in the early 1970s. The first compressor to incorporate the Sigma Profile was delivered in 1975.

Now represented in every major industrialized country in the world, Kaeser established its first subsidiary in Switzerland by the late 1970s. The US subsidiary is the largest. Reiner Mueller started the US subsidiary in Fredericksburg, VA in 1982. Fredericksburg is near to several transport centers, and remains home to the US headquarters. The 16-acre (65,000 m2) site includes a 117,500-square-foot (10,920 m2) facility. Reiner Mueller retired in December 2008, and his son Frank assumed leadership in January 2009.

Carl Kaeser, Jr., who started with Kaeser Kompressoren in 1937, worked until the day he died in 2009. Thomas Kaeser assumed leadership of Kaeser Kompressoren after his father, Carl, died at the age of 95.

Kaeser’s manufacturing facilities in Europe consist of a group headquarters in Coburg, Germany that produces rotary screw, reciprocating, and portable compressors, and a plant in Gera, Germany that produces refrigeration dryers and rotary blowers. Also, the company has a sheet metal plant near Coburg in Sonnefeld.
