Compresseur d'Air à Vis Sans Huile Classe 0 : La Solution PMV VSD pour l'Industrie Européenne
Language: English
Target market: France and European industrial buyers
THE SHORT ANSWER: CLASS 0 PURITY AND LOWER ENERGY COSTS
A dry-type oil-free PMV VSD screw compressor is a strong choice for European factories that need clean compressed air and predictable operating costs. The AquaPure series is designed for ISO 8573-1 Class 0 applications, while PMV variable-speed control can deliver an energy saving of up to 35% compared with a comparable fixed-speed system when plant demand fluctuates.
For French procurement teams searching for a compresseur d'air à vis sans huile or compresseur VSD PM, the critical question is not simply the purchase price. The right decision depends on four checks:
- Verified compressed-air purity
- Free air delivery at the required pressure
- Energy performance at the plant’s real load profile
- Complete CE, ISO 9001, technical and export documentation
The final model, pressure, airflow, voltage and configuration must be confirmed through an engineering quotation.
WHY EUROPEAN BUYERS ARE MOVING TO OIL-FREE SCREW COMPRESSION
Oil contamination is a production risk, not just a maintenance issue. In pharmaceutical manufacturing, food processing, medical equipment and electronics, oil vapour can compromise product quality, create cleaning problems or increase audit exposure.
A dry-type oil-free screw compressor keeps lubricating oil out of the compression chamber. This differs from an oil-injected compressor that depends on separator and filtration stages to control oil carryover.
That design distinction matters when compressed air contacts a product, package, process surface or critical instrument.
The AirSpace Machinery AquaPure oil-free screw compressor is intended for applications including:
- Pharmaceutical cleanrooms and tablet production
- Food and beverage processing and packaging
- Electronics and semiconductor assembly
- Medical equipment manufacturing
- Textile air-jet weaving and yarn processing
- High-purity instrument air
- Industrial blowing and contamination-sensitive processes

WHAT ISO 8573-1 CLASS 0 ACTUALLY REQUIRES
ISO 8573-1 classifies compressed-air purity by particles, water and oil. Class 0 is not a universal “zero contamination” slogan. It is a user- or supplier-defined oil specification that must be more stringent than Class 1.
A responsible European specification should therefore identify:
- The required ISO 8573-1 purity class
- The numerical oil limit
- Whether total oil includes liquid, aerosol and vapour
- The test methods used
- The laboratory or independent body responsible for verification
- The sampling location and operating conditions
ISO 8573-2 addresses liquid oil and oil aerosol testing. ISO 8573-5 addresses oil vapour testing. A Class 0 claim is meaningful only when the technical dossier defines the limit and test scope clearly.
This is why procurement teams should request the Class 0 test report, not just a brochure statement. The report should be checked against the offered compressor configuration and not a different model or laboratory setup.

THE 35% ENERGY DELTA: WHERE PMV VSD CREATES VALUE
Compressed air is often compared with a car. A fixed-speed compressor is like driving at full throttle, then using the brakes whenever the road slopes downhill. The motor keeps consuming power even when the factory does not need maximum airflow.
A PMV VSD compressor adjusts motor speed to match actual demand. When production demand falls, the system reduces speed instead of repeatedly loading and unloading at full speed.
The potential benefit is an energy reduction of up to 35% compared with a comparable fixed-speed unit under a suitable variable-load profile.
Actual savings depend on:
- Average air demand
- Operating hours per year
- Pressure setpoint
- Leakage rate
- Electricity tariff
- Number of compressors operating in parallel
- Control strategy and receiver volume
- Maintenance condition
The 35% figure should therefore be treated as an engineering target to validate, not an automatic guarantee. The most reliable method is to compare measured load data with the proposed PMV VSD operating curve.
Use the AirSpace ROI Engine to review a preliminary energy scenario using power, operating hours, pressure, demand and electricity cost.
PMV VSD VERSUS FIXED-SPEED AND OIL-INJECTED SYSTEMS
| Evaluation point | Standard fixed-speed system | Oil-injected variable-speed system | Oil-free PMV VSD system |
|---|---|---|---|
| Air output control | Load/unload or throttling | Variable speed | PMV variable speed |
| Part-load efficiency | Often poor during unload periods | Improved | Designed for demand matching |
| Oil in compression chamber | Yes | Yes | No oil in the compression chamber |
| Class 0 suitability | Requires careful filtration and verification | Requires careful filtration and verification | Designed for oil-free Class 0 applications |
| Energy opportunity | Baseline | Depends on motor and control | Up to 35% energy delta under suitable conditions |
| Recommended use | Stable, predictable demand | General industrial air | Purity-sensitive and variable-demand production |
This comparison is a planning framework. Final performance must be based on the specified model, FAD, pressure and test conditions.
HOW TO SELECT THE RIGHT COMPRESSOR FOR A EUROPEAN FACTORY
Start with air demand, not motor size. A compressor selected only by horsepower can be undersized at peak demand or wasteful during normal production.
The request for quotation should include:
- Required flow in m³/min or CFM
- Required working pressure in bar or psi
- Minimum and maximum operating pressure
- Daily and annual operating hours
- Average and peak air demand
- Ambient temperature and installation altitude
- Required ISO 8573-1 purity class
- Electrical supply and frequency
- Noise restrictions
- Available floor area
- Dryer and filtration requirements
- Destination country and export documentation
For many European plants, a complete air centre may include the oil-free PMV VSD compressor, refrigerated air dryer, receiver, filtration and condensate management. The system should be sized as one engineering package rather than as unrelated equipment.
Use the AirSpace Solution Hub to compare purity, pressure and industry requirements before requesting a quotation.

HOW TO VERIFY CE AND ISO 9001 DOCUMENTATION
European buyers should ask for a documentation package that matches the quoted equipment.
For CE verification, request:
- Declaration of Conformity
- Applicable directive and standard references
- Electrical and safety documentation
- Equipment nameplate information
- Manual and installation requirements
For ISO 9001 verification, confirm that the certificate identifies the manufacturing organisation, certification scope, certificate number, validity period and issuing certification body.
CE marking addresses conformity with applicable European requirements. ISO 9001 concerns the manufacturer’s quality management system. Neither certification replaces an ISO 8573-1 Class 0 air-purity test report.
AirSpace Machinery states that its industrial compression systems are manufactured under CE and ISO 9001 quality requirements. Buyers should still verify the documents for the specific project and configuration before purchase.
LOGISTICS, EXPORT SUPPORT AND CONFIGURATION LEAD TIME
Factory-direct planning is typically quoted within 7–35 days depending on configuration, testing, documentation and production scheduling. This is a planning range, not a fixed promise.
Before placing an order, European buyers should confirm:
- Incoterms
- Packaging and lifting points
- Electrical configuration
- Export documents
- Certificate package
- Factory testing requirements
- Spare-parts recommendations
- Installation and commissioning responsibilities
- Local service and technical-support arrangements
The Contact AirSpace Machinery page can be used to submit project requirements. Include pressure in bar or psi and airflow in m³/min or CFM so the engineering team can assess the system correctly.
THE PRACTICAL BUYING CHECKLIST
Before approving a compresseur d'air à vis sans huile, ask these questions:
- Is the offered compressor genuinely oil-free in the compression chamber?
- Is ISO 8573-1 Class 0 supported by a defined limit and test report?
- Are oil aerosol, liquid oil and oil vapour covered by the test scope?
- Is FAD stated at the required operating pressure?
- Is the 35% energy claim based on a comparable fixed-speed reference?
- Is the PMV VSD operating range suitable for the plant load profile?
- Is the maximum ambient rating suitable for the installation?
- Are CE and ISO 9001 documents available for verification?
- Are pressure and flow clearly stated in the quotation?
- Does the supplier provide a complete compressor, dryer and filtration proposal?
A low purchase price can become expensive when the system is inefficient, difficult to maintain or poorly documented. A better comparison uses total cost of ownership, purity risk, energy consumption and export support.
FREQUENTLY ASKED QUESTIONS
What is a compresseur d'air à vis sans huile?
It is a rotary screw air compressor designed without lubricating oil in the compression chamber. Dry-type oil-free systems are used where compressed-air contamination must be tightly controlled.
What does ISO 8573-1 Class 0 mean?
Class 0 means the oil-purity specification is defined by the user or supplier and is more stringent than Class 1. The exact numerical limit and test conditions must be stated in the technical documentation.
How does a compresseur VSD PM reduce energy consumption?
A PMV VSD system varies motor speed according to actual air demand. This reduces the time spent operating at inefficient full-speed unload conditions. Savings of up to 35% may be achievable under suitable load and operating conditions.
Is Class 0 air enough without a dryer?
No. Class 0 addresses oil purity. Moisture and particles are separate purity parameters under ISO 8573-1. A refrigerated air dryer, filtration and appropriate condensate management may still be required.
What information is needed for a quotation?
Provide required airflow in m³/min or CFM, working pressure in bar or psi, operating hours, demand pattern, ambient conditions, electrical supply, application and destination country.
How can a European buyer verify the supplier’s documentation?
Request the CE Declaration of Conformity, ISO 9001 certificate, ISO 8573-1 Class 0 test report, operating manual, nameplate data and the exact technical specification for the offered model.
What is the expected delivery time?
Factory-direct delivery is generally planned within 7–35 days, depending on configuration, testing, documentation and production scheduling.
