What You Need To Know About Atlas Copco Compressors


Industrial air compressors are long term investments that play a major role in your factory. That’s why it is important to choose the right one for your application.

Atlas Copco innovates for sustainable productivity with industrial air compressor systems, air treatment products, vacuum solutions and industrial power tools. The company is also known for its manufacturing of construction and mining equipment.

Air Compressors

Atlas Copco innovates for sustainable productivity across several industry segments with air compressors. These compressors can power pneumatic tools, inflate tires, spray paint, clean surfaces and other industrial tasks that need pressurized air.

The most familiar type of air compressor is a reciprocating compressor. This design features a storage tank and either a single or double cylinder. It can be a portable design with wheels or stationary and may use gas, diesel, electric motors or other power sources.

Atlas Copco compressors are essential to most automotive shops, where they are used to inflate vehicle tires and in paint sprayers to airbrush car bodies. They also power a variety of tools in woodshops and help with cabinet and furniture construction.

Variable Speed Drive Compressors

VSD compressors use an on-demand approach and reduce energy consumption. If the air demand is low, the motor slows down and the resulting energy savings are considerable.

When air demands are high, the motor speeds up again to maintain a steady pressure level. This enables manufacturers to avoid costly spikes in energy consumption and prevents waste.

In contrast, a fixed speed compressor is either running at full power or not at all. The constant switching between the two states generates a lot of electrical energy and leads to unnecessary costs.

Screw Compressors

The compressor uses two inter-twined helical-shaped screws, called rotors, to compress air. This is a very different process from that used in a piston compressor, producing much less pulsation and surging of the flow. It also is extremely efficient, consuming significantly less energy than other models.

These types of compressors come in either “dry” or “wet/oil-flooded.” Dry screw compressors have a closely mated pair of rotors installed within a tight clearance cylinder bore; wet or oil-flooded compressors, on the other hand, have lubricating oil bridged between the rotors to create a hydraulic seal and transfer mechanical energy.

Customised Compressors

Atlas Copco Gas and Process has a range of customized compressors. The integrally geared machines feature up to four pinion shafts, eight impellers and high pressure ratios in a compact design. They can be driven by a steam turbine, electric motor or gas turbine. Atlas also offers non-geared centrifugal compressors for polyolefines and main air applications that handle flow volumes of up to 500,000 m3/h and have maximum input power up to 30 MW.

These compressors can be configured with a variety of options including dry gas purifiers, liquified gas transfer, vapor recovery and other accessories. They can also be equipped with temperature sensors that monitor air inlet and discharge temperatures as well as compressor coolant and oil temperature.
