ATMOS is the leading world compressed air company. Their primary objectives in the compressed air business are rotary screw compressor manufacture including AIR END manufacturing.

The history of machine industry at present ATMOS started in 1899, when Mr. Suchy, Mr. Jouza and Mr. Cap established a foundry and machine plant.

In 1948 the factory was nationalized and incorporated into SKODA PILSEN; where the licensed serial air end production (B100) started in 1987 and the development of their own screw compressors SKD 200, 201, 202 and SKE 200 S until 1992, when SKODA PILSEN stopped the compressor production and offered the plant in Chrast for sale. A new owner, Liska and Kraus compressors ltd., bought the company including the ATMOS brand and the know-how in compressors manufacture.

The development of the new range of portable and stationary screw compressors started immediately and until the end of the year 1994 there was a serial production of 16 new models.
