First to be ISO 22000 certified
When ISO 22000 emerged as the most important global Food & Beverage quality standard, we have become the first compressor manufacturer to be awarded the certification for our Oil-free Air Division production facility in Antwerp, Belgium. Ensuring quality and transparency to our customers in the food and beverage industry.
Reliability and efficiency
When we say we have the lowest total cost of ownership possible we mean it. Maximize your production process’ uptime thanks to our globally installed service network that expands over 180 countries, combined with monitoring systems such as the Variable Speed Drive and SMARTlink that allow you to carefully plan any needed maintenance thus decreasing the span of possible downtimes.
ISO 8573-1 air quality: for the highest industry standards
Atlas Copco has set the standard for contamination-free compressed air in the food and beverage industry. You can rely on the largest range of oil free technologies within the industry, knowing that you work with the first air compressor manufacturer to achieve ISO 8573-1 (2010) Class 0 clean air, certified by TÜV Rheinland. Our compressors provide the highest quality compressed air for food processing production lines. This compressed air purity prevents contamination and safeguards your reputation.
Many industries require compliance with ISO 8573-1, the internationally recognized air quality standard. Not complying with these international standards organisations can be costly, but understanding them will bring you peace of mind.
Applications in the F&B industry
Pneumatic conveying
Compressed air is used to push powdered milk or cocoa powder along pipes. With oil-free air, you will avoid oil contaminant mixing with the powder and maintain the powder purity.
Automation air
Compressed air is used to control the valves and actuators in automated lines for filling, packaging and bottling. Oil-free compressed air keeps your end product safe.
Air blowing, aeration
Compressed air is pumped into a liquid to boost its oxygen content. This is used, for example, in fish farming to oxygenate water in lower layers and/or oxidize the sediments.
Cooling and spraying
Compressed air is used to cool down baked goods after they emerge from the oven. Contamination of the air spoils the end product leading to rejections and production losses.

Common questions
Can oil-injected compressors with oil removal filters deliver oil-free air?
This solution is often referred to as “technically oil-free air”. However, even under optimum conditions and with several stages of oil removal, the air quality with regard to oil is suspect.
With oil-injected compressors there will always be a risk of contamination and the possibility of severe consequences for the business. With Atlas Copco’s oil-free air compressors, you’re choosing for zero risks, as oil-free air is 100% guaranteed oil-free.. Know more.
What about oil contamination in ambient air?
Ambient air has very small traces of oil coming from vehicles and industrial sources. However, in contaminated areas, oil content does not normally exceed 0.003 mg/m3.
This is borne out by tests conducted by the TÜV near a factory with heavy machining activity (including turning, milling, grinding and drilling). Heavy vehicular traffic and a garbage incinerator were in the vicinity.
Aspirated by an oil-free air compressor, this extremely low level of atmospheric oil is washed away by the condensate in the intercooler and aftercooler, resulting in pure oil-free air for your process. Know more.
What are the TÜV tests required to qualify for ISO 8573-1 CLASS 0?
The Part 2 test measures aerosols and liquids. Testing can be done through partial flow (B2) or full flow (B1) methods (see below). The Part 5 test measures vapor only. Both parts are necessary to obtain ISO 8573 CLASS 0 certification. This means that all three sources of oil contamination – aerosol, vapor, and liquid – have to be measured.
What is the essential difference between partial flow (B2) and full flow (B1) testing methods?
Both methods are acceptable for aerosol and liquid measurement according to ISO 8573-1 Part 2 The B2 method targets only the center of the airflow. Oil aerosols are registered but oil that sticks to the pipe wall (wall flow) is not detected. Most air compressor manufacturers still prefer this less stringent method. The B1 method examines the entire air flow to measure both aerosols and wall flow. This comprehensive test method was used on the Atlas Copco range of oil-free air compressors. Even so, no traces of oil were found in the output air stream.
