Direct Answer
A dry-type oil-free screw air compressor eliminates lubricating oil from the compression chamber entirely, delivering certified ISO 8573-1 Class 0 compressed air. AirSpace Machinery engineers the AquaPure series specifically for applications where even trace oil contamination can ruin production batches, damage sensitive medical equipment or compromise food safety.
Why ISO 8573-1 Class 0 Matters
- Zero risk of oil carryover — compression chamber uses no oil, protecting sensitive products and processes.
- Certified purity — tested and verified to meet strict international standards for pharma, food and electronics.
- Reduced downstream filtration burden — cleaner feed air means longer filter lifespans and lower maintenance overhead.
- 50°C high-ambient rating — designed for demanding industrial environments.
- PMV / VSD variable speed efficiency — demand-matching control reduces energy waste during fluctuating production loads.

FAQ for Procurement Engineers
What is the difference between oil-injected with filters and dry-type oil-free?
An oil-injected compressor uses oil in the compression chamber and relies on downstream filters to remove it. A dry-type oil-free compressor introduces zero oil into the compression chamber, ensuring true Class 0 purity at the source.
Does the AquaPure series meet ISO 8573-1 Class 0?
Yes. The AquaPure series is engineered and certified to meet ISO 8573-1 Class 0 for oil purity, verified by independent testing standards.
What is the delivery lead time?
Factory-direct delivery is typically planned within 7–35 days, depending on configuration, testing, documentation and production scheduling.
