Introduction
When it comes to compressed air quality, Class 0 oil-free certification is the gold standard. Seize Compressor (Shanghai) Co., Ltd. has achieved this prestigious certification for both its dry screw air compressors and water-injected single screw air compressors, proving their commitment to delivering 100% oil-free air for critical applications.
In this article, we’ll explore:
✔ What ISO 8573-1 Class 0 certification means
✔ Why Seize Compressor’s oil-free and water-lubricated models stand out
✔ The benefits of Class 0 certified air compressors
✔ How Seize ensures zero oil contamination in compressed air
What is ISO 8573-1 Class 0 Certification?
The ISO 8573-1 standard classifies compressed air purity based on oil content, with Class 0 being the strictest level. Unlike Class 1 (which allows minimal oil), Class 0 means absolutely no oil contamination—essential for industries like:
✅ Pharmaceuticals (no risk of product contamination)
✅ Food & Beverage (ensures safe air contact with consumables)
✅ Electronics (prevents damage to sensitive components)
✅ Medical & Dental (sterile air for breathing and equipment)
Seize Compressor’s dry screw (oil-free) and water-injected models have been rigorously tested and certified by Hefei General Machinery Product Certification Co., Ltd., meeting:
- ISO 8573-1:2010 (air purity classification)
- ISO 8573-2:2018 (testing methods)
- ISO 8573-5:2001 (oil content measurement)
This certification ensures zero risk of oil carryover, making Seize compressors ideal for critical applications.
Seize Compressor’s Class 0 Certified Models
1. Dry Screw Air Compressors (Oil-Free Technology)
Seize’s dry screw air compressors (model series: SWT-37W, SWT-55W, SWT-75W, etc.) use advanced oil-free screw technology, eliminating the need for lubricating oil in the compression chamber.
🔹 Key Features:
✔ 100% oil-free air output (Class 0 certified)
✔ Energy-efficient design (reduces operating costs)
✔ Low maintenance (no oil changes or filters needed)
✔ Wide range of models (from 37kW to 355kW)
These compressors are perfect for industries where even trace oil contamination is unacceptable.
2. Water-Injected Single Screw Air Compressors
Seize’s water-injected models (e.g., SWVC-06A, SWVC-11A, SWVC-15A, etc.) use water as a lubricant and coolant, ensuring zero oil contamination while improving efficiency.
🔹 Key Advantages:
✔ Class 0 certified (no oil in compressed air)
✔ Lower operating temperatures (water cooling enhances durability)
✔ Quieter operation (reduced mechanical friction)
✔ Cost-effective (no oil-related maintenance)
These compressors are ideal for food processing, breweries, and medical applications where clean, oil-free air is mandatory.
Why Choose Seize Compressor’s Class 0 Certified Air Compressors?
1. Guaranteed Oil-Free Air
Many compressors claim to be “oil-free,” but only Class 0 certification provides absolute proof of zero oil contamination. Seize’s compressors undergo strict testing to ensure compliance.
2. Lower Total Cost of Ownership (TCO)
- No oil changes = reduced maintenance costs
- No oil filters = fewer replacement parts
- Energy-efficient = lower electricity bills
3. Compliance with Industry Regulations
Industries like pharmaceuticals (GMP), food (FDA), and electronics (ISO 8573-1) require Class 0 air. Seize’s certification ensures compliance with global standards.
4. Enhanced Equipment Longevity
Oil contamination can damage downstream equipment (dryers, filters, pneumatic tools). With Seize’s Class 0 compressors, you eliminate this risk, extending equipment lifespan.
How Seize Ensures Zero Oil Contamination
Seize Compressor’s certification process includes:
✅ First Inspection (initial product testing)
✅ Design Evaluation (ensuring no oil ingress points)
✅ Follow-Up Inspections (ongoing compliance checks)
This multi-stage verification guarantees consistent oil-free performance throughout the compressor’s lifespan.
Conclusion: Trust Seize for True Oil-Free Air
Seize Compressor’s ISO 8573-1 Class 0 certification for both dry screw and water-injected models sets them apart in the compressed air industry. Whether you need 100% oil-free air for medical, food, or electronics, Seize delivers reliable, certified performance.
