Compressors

1904: First piston air compressor manufactured by Atlas.
1905: First portable air compressor manufactured by Atlas.
1933: Introduction of a portable mono-block diesel engine compressor with a direct injection four-cylinder diesel engine, the C4DKV.
1936: Production of the first air-cooled stationary compressors, the HF and the GF series. Both series ran at 1000 rpm.
1945: Introduction of an air-cooled stationary compressor. The NT compressor ran at speeds up to 1500 rpm and was driven by an electric motor, flanged directly to the compressor. The NT compressor offered another advantage: it was well suited for mass production.

1949: Introduction of the first completely air-cooled portable diesel compressor.
1954: Launch of a completely new compressor type, the screw compressor. The compressor was based on an innovation, patented by Professor Alf Lysholm.
1958: Launch of the world´s first portable screw compressor, the PR type, in two capacities — the PR 365 (10,3 m3 /min) and the PR 600 (17m3 / min).
1958: Delivery of the first Airpartner, a truck-mounted screw compressor used in starting jet engines. The Airpartner has since been delivered to airlines all over the world.

1967: Launch of a series of stationary, oil-free, electrically driven compressors, the Z series. The ZR type, which was manufactured as a complete unit with an electric motor aftercooler and all other units built in to a noise-suppressing canopy, was a commercial success for Atlas Copco.
1967: Introduction of the PT compressor, a portable high-rpm screw compressor that produced oil-free air.
1989: Launch of the H-Series plant air turbo compressor. The compressor was designed to be used in such industries as air separation, process, petrochemical, pharmaceutical, automotive, utility and mining.
1994: Launch of a variable speed compressor, the VSD compressor range. The key feature of a VSD compressor is its ability to adjust output by varying the speed of its drive motor, thus reducing energy consumption to a minimum. This can cut the cost of compressed air energy by up to 35 percent compared to a conventional type.
1997: New range of large oil-free screw compressors aimed at the electronics, pharmaceutical and automotive industries.
