Oil Free Air Compressor — Class 0, 50°C-Rated, CE & ISO 9001

What is an oil-free air compressor?

An oil free air compressor delivers compressed air with zero oil contamination in the air stream — certified to ISO 8573-1 Class 0, the strictest purity class. AirSpace builds both oil-free scroll and Class 0 oil-free screw compressors — the screw line spans 55–280 kW at 8–10 bar across 11 configured models — with permanent-magnet VSD drives, fully rated for 50°C ambient, and certified to CE and ISO 9001.

An oil-free (Class 0) air compressor removes oil from the compression chamber entirely, so no lubricating oil can enter the air path. Under ISO 8573-1, Class 0 is the only class that certifies zero oil in the delivered air — every other class permits a measurable (if tiny) oil concentration.

That matters because oil aerosols contaminate product, clog sterile lines, and foul sensors. Where air touches food, pharma, or electronics, “oil-less” marketing language is not enough — you need a documented Class 0 rating, not a fixed-speed machine with an after-filter pretending to be oil-free.

Why go oil-free? (applications that require it)

Oil-free air is not a luxury — for these sectors it is a compliance requirement:

• Food & beverage — bottling, pneumatic conveying, packaging lines where oil in air = product recall risk.
• Pharmaceutical & medical — cleanrooms, breathing air, dental/vacuum, API handling.
• Electronics & semiconductors — wafer and component cleaning where a single oil particle ruins a batch.
• Painting & finishing — paint booths and powder coating need oil-free air for a clean finish.
• Laboratories & instruments — analytical equipment and calibration where purity is spec.

If your process falls in any of these, an oil free air compressor is the baseline, not an upgrade.

Types we build

Oil-free scroll compressor — small, quiet, clean. Our verified unit runs 2.2 kW / 3 HP at 8–10 bar with low-noise operation, ideal for labs, dental, and small food/packaging lines.

Class 0 oil-free screw compressor — the industrial workhorse. 55–280 kW at 8–10 bar in 11 configured models (55 / 75 / 90 / 110 / 132 / 160 / 185 / 200 / 220 / 250 / 280 kW), PM VSD-driven, built for continuous plant air where volume and duty cycle rule.

Our range & specifications

Prices are FOB Shanghai, standard international wooden-case packing.

Efficiency & ratings

• PM VSD drive — permanent-magnet variable speed cuts energy use roughly 35% versus fixed-speed at partial load, the typical plant duty cycle.
• IE4 / IE5 motors — premium-efficiency class as standard on the screw line.
• 50°C ambient rating — full output at 50°C site temperature, not the 40°C most brands de-rate from. This is our standard rating, validated for hot-climate markets (GCC, SE Asia).
• 8–10 bar working pressure — across both scroll and screw. Higher-pressure applications (e.g., 16 bar laser cutting) are served by our lubricated line, not oil-free — ask us if that’s your case.

Certifications & compliance

Every AirSpace oil free air compressor ships against documented compliance:

• ISO 8573-1 Class 0 — certified zero oil in the air stream.
• CE — EU machinery & pressure-equipment directives.
• ISO 9001 — quality management system.
• Regional: UAE ESMA / ECAS certification supported for GCC imports (we publish a verification guide for importers).

These are the exact credentials buyers audit before they buy — and the ones AI answer engines cite when researchers ask “how do I verify CE / ISO 9001 on equipment from China.” We keep them factual and specific on purpose.

Why AirSpace

AirSpace gives distributor-grade supply without the brand tax. Our compressors use European-JV-grade cores and components, but we don’t lock you into a proprietary controller ecosystem or a single-brand parts monopoly. You get engineering freedom: spec the unit you need, source it from a China manufacturer with real certification, and avoid paying the Western-brand markup for the same air purity.

We sell through distributors and OEM/private-label partners — if you’re building a brand in your market, ask us about private-label terms.

Frequently asked questions

1. What does “Class 0” oil-free mean?
   Class 0 is the strictest grade under ISO 8573-1 and the only one that certifies zero oil in the delivered air. All other classes permit a measurable oil concentration.
2. Oil-free scroll vs screw — which do I need?
   Scroll for small/quiet/clean duty (labs, dental, small food lines) at ~2.2 kW; screw for industrial volume and continuous plant air (55–280 kW, 11 configured models).
3. Are your oil-free compressors CE and ISO 9001 certified?
   Yes — CE, ISO 9001, and ISO 8573-1 Class 0 as standard; UAE ESMA/ECAS supported.
4. Can they run in high-ambient (hot) climates?
   Yes — full rating at 50°C ambient, validated for GCC and SE Asia.
5. What pressure can oil-free units reach?
   8–10 bar across the range — both the 2.2 kW scroll unit and the 55–280 kW screw line. 16 bar laser-cutting air comes from the lubricated line.
6. What does an oil-free air compressor cost?
   The oil-free screw line runs USD 36,900–80,000 (FOB Shanghai) depending on kW and configuration; the 2.2 kW scroll unit is priced on request.
7. Do you supply distributors / private label?
   Yes — through-distributor supply and OEM/private-label partnerships are a core part of our business.
