In beverage production, compressed air can touch the product through filling, bottling and cap handling. Oil-free screw compressors remove the risk of oil contamination at the source.
Product-Contact Air Requirements
Air that contacts containers or product must be clean, dry and oil-free. A Class 0 oil-free compressor plus filtration and drying is the standard approach.
Where Compressed Air Is Used
- Bottle blowing and rinsing
- Filling and capping
- Conveyor and valve actuation
- Labeling and packaging
Why Oil-Free Is Safer
Oil-free designs eliminate the oil carryover that can taint flavor and fail food-safety audits. They also simplify compliance documentation.
Keeping the System Food-Safe
- Install desiccant or refrigerated drying for the required dew point
- Add coalescing and carbon filtration downstream
- Monitor dew point and filter differential pressure
- Schedule point-of-use filter replacement
Total Cost Consideration
Oil-free machines cost more up front but avoid expensive batch contamination and recall risk, making them the right choice for beverage lines.
