ISO 8573 Compressed Air Filter: Precision Filtration for Industrial Air Quality
Product Introduction
The ISO 8573 Compressed Air Filter is a state-of-the-art filtration system engineered to meet the stringent air quality standards outlined in the ISO 8573 series for compressed air purity. Designed for industries reliant on compressed air—such as manufacturing, food and beverage, pharmaceuticals, and electronics—this filter ensures the removal of contaminants including particles, water, oil aerosols, and vapors. Certified to ISO 8573-1 (Classification of Air Quality), it guarantees contamination levels as low as Class 0 (highest purity), protecting sensitive processes, equipment, and end-products from degradation.
Key Features & Advantages
1. ISO 8573-Certified Air Quality
Multi-Class Compliance: Delivers air purity up to ISO 8573-1 Class 0 (≤0.01 mg/m³ oil content, ≤0.1 μm particles, and ≤-40°F dew point).
Customizable Configurations: Modular design allows staging for specific contamination targets (e.g., oil removal, particulate filtration, or drying).
2. Ultra-High Filtration Efficiency
Beta Ratio (β) > 100,000: Removes 99.999% of particles ≥0.01 μm, including submicron oil aerosols and rust particles.
Coalescing Technology: Merges microscopic oil droplets into larger droplets for gravity separation, achieving 99.9% oil carryover reduction.
3. Extreme Durability
Material Resistance: PTFE-coated glass fibers, stainless steel housings, and EPDM/Viton seals withstand corrosive oils, acids, and extreme temperatures (-40°C to +120°C / -40°F to +248°F).
Longevity: 36–60 months lifespan in harsh industrial environments (vs. 12–24 months for standard filters).
4. Energy Efficiency
Low Pressure Drop (<0.03 bar): Optimized flow paths reduce energy consumption by up to 20% compared to conventional filters.
Cold Start Capability: Self-draining design prevents freeze-ups in low-temperature applications.
5. Compliance & Certification
Certifications: ISO 8573-1, ISO 14001 (environmental), FDA 21 CFR (food-grade compatibility), and PED 2014/68/EU (pressure equipment).
Working Principle
The ISO 8573 Compressed Air Filter integrates advanced filtration stages to achieve multi-level purification:
1. Pre-Filtration (Optional)
2. Coalescing Stage
Capture: Airborne oil aerosols and particulates collide with hydrophobic/oleophobic media fibers, aided by electrostatic charges.
Merging: Contaminants merge into droplets (50–1000 μm) due to media tortuosity and surface tension.
3. Separation & Discharge
Gravity Separation: Enlarged droplets settle at the filter’s base and drain via an automatic float valve.
Clean Air Exit: Purified air exits through a high-efficiency membrane or activated carbon layer (for vapor removal), meeting ISO 8573-1 Class 0–3 standards.
Application Scenarios
1. Manufacturing Automation
Challenge: Compressed air contaminated with oil, dust, and moisture damages pneumatic tools, valves, and sensors.
Solution: Removes 99.9% of oil aerosols (β>100,000) and particles (Class 1–3), ensuring tool longevity and product quality.
2. Food & Beverage Packaging
Challenge: Compressed air used in filling lines risks oil contamination, spoilage, and regulatory non-compliance.
Solution: FDA-compliant PTFE media and stainless steel construction ensure oil-free air (<0.01 mg/m³), meeting ISO 8573-1 Class 0 standards.
3. Pharmaceutical Cleanrooms
Challenge: Compressed air must be sterile and contaminant-free to prevent cross-contamination in drug manufacturing.
Solution: HEPA-grade particulate filtration (Class 1) and activated carbon adsorption (Class 0 oil vapor) ensure air purity for sensitive processes.
4. Electronics Manufacturing
Challenge: Moisture and particles in compressed air cause corrosion and defects in PCBs and microchips.
Solution: Dew point suppression to -70°C and submicron filtration (Class 0) protect sensitive electronics.

Maintenance Guidelines
1. Routine Inspection
Differential Pressure (ΔP): Monitor weekly; replace media if ΔP exceeds 0.1 bar (initial ΔP: 0.02–0.05 bar).
Visual Checks: Inspect for oil carryover, moisture discharge, or seal degradation (monthly).
2. Media Replacement
3. Cleaning Protocols
4. Troubleshooting
Oil Bypass: Check for damaged O-rings or exceeded β-ratio limits.
Moisture Carryover: Verify dryer performance and filter staging (e.g., coalescer + dryer combination).
8 Frequently Asked Questions (FAQs)
1. What contaminants does the ISO 8573 Filter remove?
It targets particles (0.01–100 μm), oil aerosols (down to 0.01 mg/m³), and water vapor (dew points as low as -70°C).
2. How does it differ from standard compressed air filters?
Standard filters lack ISO 8573 certification and typically achieve only Class 1–3 purity. This filter guarantees Class 0–3 performance.
3. Is it suitable for food-grade applications?
Yes. FDA-compliant materials and <0.01 mg/m³ oil content meet USDA/FDA requirements for indirect food contact.
4. Can it handle high-temperature compressed air?
Yes. PTFE-coated media and stainless steel construction resist temperatures up to +120°C (+248°F).
5. What is the maximum flow rate?
Up to 1000 Nm³/h for industrial-scale systems.
