In high-stakes manufacturing, “almost clean” is a recipe for disaster. For industries like pharmaceuticals, food processing, and electronics, the International Organization for Standardization created a definitive benchmark for air purity: ISO 8573-1 Class 0. As an elite Netherlands-based engineering firm, EVER POWER is dedicated to showing you exactly how our water-lubricated technology achieves and guarantees this standard.
1. Product Overview: The Zero-Tolerance Solution
Class 0 does not mean “zero contamination”—it means zero added oil contamination from the compressor itself, tested under the most stringent conditions. Water injected compressors achieve this by physically removing oil from the entire compression architecture.
- Quick Industry Applicability: Medical breathing air, semiconductor fabrication, vaccine production, and infant formula packaging.
- Core Advantages Summary: 100% elimination of oil aerosol, oil vapor, and liquid oil carryover. Protects brand equity, eliminates product spoilage, and simplifies regulatory audits.
2. Technical Parameters (Purity Focused)
Achieving Class 0 requires robust engineering. Here are the specs of our standard units designed specifically for high-purity applications.
| Model Series | Oil Carryover (mg/m3) | ISO 8573-1 Oil Class | Discharge Temp Target | Lubricant Used |
|---|---|---|---|---|
| EP-WI-22 to 75 | 0.00 | Class 0 | < 50 degrees C | RO Purified Water |
| EP-WI-90 to 160 | 0.00 | Class 0 | < 50 degrees C | RO Purified Water |
| Standard Oil-Flooded (for comparison) | 0.01 to 3.00+ (even with filters) | Class 1, 2, or 3 | 80 – 100 degrees C | Synthetic Oil |
3. The Principle of Absolute Purity
Attempting to achieve Class 0 with an oil-lubricated compressor relies on a complex cascade of downstream filters. This is a fragile system; if one filter ruptures, your entire production line is contaminated.
EVER POWER operates on the principle of prevention over filtration. In our water-injected machines, oil is completely absent from the compression chamber. The rotors are sealed and cooled by demineralized water. Because there is no oil present in the mechanical process, it is physically impossible for the compressor to add oil to the air stream. Therefore, the air leaving the machine meets Class 0 specifications intrinsically, without relying on vulnerable downstream oil filters.
4. Five Core Advantages of True Class 0 Air
🛡️ Uncompromised Safety
Guarantees that your food, medicine, or electronics are safe from hydrocarbon contamination, protecting consumers and your brand.
💸 Eliminated Filter Costs
Stop buying expensive inline activated carbon filters and coalescing oil filters. The air is clean straight from the compressor.
📉 Reduced Pressure Drop
Removing complex downstream oil filters eliminates the pressure drop they cause, saving significant electrical energy over the year.
📋 Simplified Audits
Providing an ISO 8573-1 Class 0 certificate to FDA or local health inspectors instantly validates your utility safety protocols.
🌿 Zero Oil Waste
Complying with environmental standards is easy when you generate zero toxic oil-water condensate. It’s the greenest way to compress air.
5. Structure and Hygienic Design
To maintain Class 0 purity, the internal components of the EVER POWER compressor must not shed particles. We utilize advanced polymer-ceramic rotors and bronze housings. These materials will not corrode or introduce rust particles into the air stream. Furthermore, the air-end is physically separated from the gear/motor casing via advanced labyrinth seals, ensuring that bearing grease in the motor can never migrate into the compression chamber.
6. Typical Application Scenarios (Class 0 Mandated)
Certain industries legally or practically require this standard:
- Biotechnology & Pharma: Used in fermentation tanks for vaccine production. Oil kills bacteria/yeast and ruins multimillion-dollar batches.
- Semiconductor Wafer Fabs: Microchips are destroyed by even a single molecule of oil vapor. Class 0 air is used for pneumatic transport and cleaning inside cleanrooms.
- Automotive Paint Lines: High-end car manufacturers use Class 0 air for spray painting to ensure perfect adherence and a flawless, mirror-like finish.
7. Selection Guide: Beyond Just the Compressor
Achieving Class 0 air at the point of use requires looking at the whole system:
- Address the Piping: If you install a new Class 0 EVER POWER compressor onto old, galvanized steel pipes that previously handled oil-flooded air, your final product will still be contaminated. You must flush or replace old piping with stainless steel or aluminum.
- Manage the Moisture: ISO 8573-1 also dictates water content (dew point). Water-injected compressors produce wet air. You must install a proper refrigerated or desiccant dryer to meet the moisture class required by your process.
- Ambient Air Quality: The compressor cannot remove hydrocarbons already present in the ambient factory air (e.g., from forklift exhaust). Ensure the compressor air intake is located in a clean, well-ventilated area.

10. Global Case Studies
📍 Client: Pharmaceutical Manufacturer in France
Application: Clean room air and pill coating.
Feedback: “Compliance is everything in pharma. Having the EVER POWER Class 0 certification on file made our recent health inspection seamless. The machine is incredibly quiet and completely reliable.”
📍 Client: Automotive Assembly in Mexico

12. Frequently Asked Questions (FAQ)
Q1: If the air is Class 0 for oil, is it also Class 0 for water?
A: No. ISO 8573-1 categorizes oil, water, and solid particulates separately. A water-injected compressor gives you Class 0 for oil. To achieve a high class for water (low dew point), you must pair it with a desiccant air dryer.
Q2: Can standard “Oil-Free” teflon-coated dry screws achieve Class 0?
A: Yes, dry screw compressors can also achieve Class 0. However, they operate at much higher temperatures (200 degrees C vs. our 50 degrees C) and are generally louder and more expensive to purchase and rebuild than EVER POWER’s water-injected design.
