Where Is Compressed Air Used in Food & Beverage Processing?
Compressed air is used widely in food production, from operating machinery to packaging, where it may come into direct contact with food products.
Common Applications
Compressed air can be used to power conveyance and sorter systems that transport food products and ingredients.
Compressed air systems efficiently rinse, clean, and dry bottles.
Compressed air is an essential component in safely and effectively sealing and packaging food products.
In dairy processing, compressed air is beneficial for mixing and blending operations.
Compressed air carbonates drinks and is used for food drying and preservation processes.
Compressed air is used with pneumatic carton machines and sealing systems.
Why Clean Air Matters in Food Production
Contaminated air can compromise food safety and quality. Air from a Delta system is free from moisture, particles, and oil to protect product integrity, and ensure compliance with regulations and standards.
- Particles. Rust, dust, and mold spores are common particles that can contaminate food.
- Water. Condensation in food packaging or on products can lead to microbial growth.
- Oil. Carryover from compressors or ambient air is another major factor that can compromise food safety.

Understanding Compressed Air Standards in Food & Beverage
The purity of compressed air is specified by ISO 8573-1:2010 for these three types of contaminants:
- [A] Dry Particulate (i.e., solids)
- [B] Humidity/Water (i.e., liquid or vapor)
- [C] Oil Concentration (i.e., liquid, vapor, or aerosol)
Recommended Air Purity Classes
Each of the forms of contaminants is numerically classified based on allowable levels. Different applications and operations have different required levels of each type of contaminant, for example:
- Direct Food Contact. The requirement is 2:2:1 or better, which means a level of 2 or lower is required for both particle and water contamination, and 1 or lower for oil contamination. SQF Code 11.5.5 states compressed air that comes into direct contact with food must be clean and hazard free.
- Indirect Food Contact. The requirement is 2:4:2 or better, which means level 2 or lower for particle and oil contamination, and 4 or lower for water contamination.
Application Type Air Purity Classes
| Application Type | Dry Particulate (A) | Humidity & Water (B) | Oil (C) | Example Uses |
|---|---|---|---|---|
| Direct Contact | Class 2 | Class 2 | Class 1 | Blow-off of produce, drying containers, packaging in sterile environments |
| Indirect Contact | Class 2 | Class 4 | Class 2 | Powering conveyors, mixers, sorters, and other food production equipment |
