Every day, across the globe, products are made, factories are built and critical bolts are fastened with compressors powered by Atlas Copco. And, it’s all done with clean, oil-free compressed air.
Atlas Copco compressors are used in nine out of ten factories. They’re also found in many homes and garages, inflating car or bike tyres and for small projects.
Reciprocating Compressors
Reciprocating compressors, also known as piston air compressors, are positive displacement machines that use a piston in a chamber called a cylinder to decrease volume and increase pressure. They can be categorised as lubricated or oil-free, and they may operate in two strokes; one side of the piston sucks in the air, while the other side compresses it.
This type of compressor is ideal for tasks that require intermittent air usage, as it maintains high efficiency during these intermittent cycles. These compressors are a great choice for DIYers and homeowners who want a portable air compressor to run manual tools or inflate car or bike tires.
Rotary Screw Compressors
When you need air that works as hard as you do, rotary screw compressors deliver. These workhorses are designed to operate 24 hours a day, 7 days a week for years without overheating, saving you time and money.
They have a smaller footprint than reciprocating compressors and can be used on trucks and trailers, or mounted on a shop floor. This means you can haul more equipment and tools, save on fuel costs and have the ability to work right where you need to.
Oil-Free Air Compressors
The oil-free air compressor does not contain any lubricants and provides compressed air free from any contamination beyond the natural contaminants found in the air itself. This makes it a smart choice for applications where even traces of oil could ruin the end product or create health hazards.
Breweries use oil-free compressed air for sorting and ejecting beer, mixing and aerating ingredients, packaging, bottling, and automated production lines. Atlas Copco’s rotary screw air compressors, nitrogen generators and blowers are used to provide high-quality, oil-free compressed air in these facilities.
Nitrogen Generators
Nitrogen generators provide an on-demand source of pure nitrogen. They work by passing dry compressed air through semi-permeable membrane fibres. The membranes separate oxygen molecules from nitrogen molecules and other trace gases and discharge the pure nitrogen gas.
These generators come as plug-and-play units that can be connected to a compressor system and supplied with a supply of dry compressed air.
They feature premium carbon molecular sieve adsorbents and advanced software, including Variable Cycle Saver (VCS), which optimizes the PSA cycle for energy savings and stand-by mode to avoid unnecessary air consumption.
