Compressed air in the food and beverage industry

Maximum air quality up to Class 0 for the highest demands

In the food and beverage industry, compressed air is an essential medium that plays a key role throughout almost every stage of production — from raw material processing through to filling, packaging, cleaning and drying of products and containers. As a versatile energy source, it reliably powers conveying and packaging systems, ensures precise control of valves and cylinders, and is used directly as process air in numerous applications, including blowing off, mixing, aerating and the pneumatic conveying of ingredients. A safe and stable compressed air supply also forms the basis for nitrogen generation used for inerting and for protecting sensitive products from oxidation.

The requirements placed on compressors, blowers and boosters in this sensitive sector are exceptionally high. The compressed air must consistently achieve the required levels of purity, dryness and stability to safeguard product quality, shelf life and safety.

With durable components, energy-efficient treatment technologies and intelligent control systems, KAESER compressors ensure a permanently stable and process-safe compressed air supply – around the clock.

Efficiency, maintenance and heat recovery

In the food and beverage industry, the compressed air supply is often one of the largest energy consumers within a production facility. Energy-efficient system design is therefore essential. KAESER compressors, blowers and boosters are engineered to significantly reduce energy consumption and to lower Total Cost of Ownership (TCO) over the long term – all while maintaining exceptional process reliability.

Heat recovery offers an additional advantage: Up to 96% of the heat generated during compression can be reused effectively, for example to heat process water or for space-heating purposes. This increases overall plant efficiency and supports resource-efficient, sustainable production.

Thoughtfully designed maintenance concepts and excellent accessibility to all key components enable fast, planned service intervals and extend system service life. As a result, the compressed air supply remains consistently reliable, economical and efficient – even in hygiene-critical and demanding production environments.

Interesting facts

FAQs, facts and useful insights about the food and beverage industry

In the food and beverage industry, compressed air is subject to particularly stringent hygiene and safety requirements. The key standard governing compressed air quality is ISO 8573-1, which defines purity classes for particles, water and oil. For applications where compressed air comes into direct contact with products or product-contact surfaces, Class 0 is essential, as it ensures oil-free, virtually particle-free and hygienically safe air.

Minimising the risk of contamination is equally important. Food safety standards such as ISO 22000, the use of food-grade materials and a robust HACCP risk management system enable KAESER, as a compressed air systems provider, to support the food and beverage industry reliably in its highly regulated processes.
