Why Food & Beverage Needs Oil-Free Class 0 Air
When compressed air can contact food, beverages or product-contact surfaces, air purity matters.
Oil-free compressed air helps reduce the risk of lubricant contamination in critical production processes such as filling, packaging, conveying and PET bottle blowing.
Why Choose Class 0 Oil-Free Air?
01 | Minimize Oil Contamination
No oil-based lubricant is used in the compression chamber, helping reduce the risk of oil carryover from the compression process.
02 | Support Clean Production
Suitable for critical applications where compressed air purity is an important production requirement.
03 | Protect Your Process
Combine oil-free compression with the right dryer and precision filtration to control oil, moisture and particles.

How to Choose the Right
Compressed Air Purity for Food Production
The right compressed air quality depends on where the air is used, whether it contacts the product, and how much moisture and contamination control your process requires.
Choose Your Air Quality in 3 Steps
01 — Check Air Contact
Does compressed air contact food, beverages or product-contact surfaces?
YES → Consider Class 0 Oil-Free Air
Ideal for critical applications such as filling, packaging, conveying and PET bottle blowing.
02 — Choose Your Pressure Dew Point
Select the right dryer according to your production requirements:
- Refrigerated Air Dryer:2–10a°C – For general production and packaging.
- Desiccant Air Dryer:-20 to -40°C – For applications requiring lower moisture levels.
- Zero Loss Blower Heta Dryer:≤ -40°C – For demanding dry-air applications.
03 — Match Your Filtration
Combine the compressor with the appropriate precision filtration to help control oil, water and particles.

Frequently Asked Questions
Is an oil-free air compressor mandatory for the food industry?
Not necessarily; it depends on whether the air comes into direct contact with the product. For direct-contact applications (such as mixing, fermentation, or raw material conveying), using an ISO Class 0 certified oil-free compressor is strongly recommended. For non-contact applications (such as powering pneumatic cylinders), a high-quality oil-lubricated screw compressor paired with a high-efficiency oil-removal filter can meet food safety standards while offering better cost-effectiveness. Sollant can provide the most suitable solution based on your specific processes.
How can the dryness of the compressed air be ensured?
Compressed air contains significant moisture, which condenses into liquid water upon cooling. It is essential to use a refrigerated air dryer (to lower the pressure dew point to 2–10°C) or an adsorption dryer (capable of lowering the pressure dew point to between -20°C and -70°C). Sollant offers a comprehensive range of dryers to ensure there is no liquid water in your piping system, thereby preventing bacterial growth.
How do air compressors operate stably in harsh environments characterized by high temperatures, high humidity, or prolonged operation?
Handling high temperatures: Utilize large-sized coolers and high-efficiency fans, and use fully synthetic lubricants (for details, please refer to High-Temperature Management for Screw Air Compressors) to ensure the unit does not trip at ambient temperatures of 45°C.
Handling high humidity: High-efficiency intake filtration and air-water separators are installed, combined with refrigerated dryers, to ensure the timely discharge of condensate.
Handling prolonged operation: The airend is designed for heavy-duty, continuous operation; variable frequency drives (VFD) and soft-start technology minimize mechanical stress, while rotational operation among multiple units prevents equipment fatigue.
What are the specific requirements for compressed air across different stages of the process, such as PET bottle blowing, filling, and packaging?
| Work Section | Pressure Requirement | Core Quality Requirement |
| PET bottle blowing | 30–40 bar | Must be oil-free (Class 0) |
| Filling | 5–8 bar | Must be oil-free (Class 0) |
| Packaging | 4–6 bar | No strict oil-free requirement |
| Instrument air | 5–7 bar | Highly dry (-20°C dew point) |
How often does the compressed air system require maintenance?
| Item | Frequency |
| Daily checks (liquid level, alarms, drainage) | Daily |
| Air filter | 500–1,000 hours |
| Oil filter | 1,000–2,000 hours |
| Oil-Air Separator | 2,000–4,000 hours |
| Lubricating Oil (Mineral/Fully Synthetic) | 2,000–4,000 / 8,000 hours |
| Cooler cleaning | 3–6 months |
| Safety Valve Calibration | Once a year |
| Complete machine overhaul | 20,000–24,000 hours |
Maintenance intervals must be shortened for environments characterized by high temperatures, high humidity, or heavy dust.
