Compressed Air Treatment: Filtration Adds Value
Compressed air treatment is more than just a series of filtration steps. Each stage offers opportunities to improve efficiency, reliability, and regulatory compliance. We help you optimize every step of the process, ensure consistently high compressed air quality, and simultaneously eliminate system vulnerabilities and energy losses.
1. Particle filtration
An optimized filter design reduces pressure drop and protects downstream components. This ensures a longer service life for the equipment and stable system operation. We offer high-performance filter elements for compressed air filtration that efficiently remove solid contaminants such as dust and rust.
2. Oil and Aerosol Separation
Our coalescing filters perform reliable filtration of oil aerosols and fine droplets, helping to reduce operating costs. They minimize the risk of contamination and ensure consistently high compressed air quality, particularly in applications involving sensitive processes or product contact. Filter Elements with low pressure drop enable cost savings in your compressed air system.
3. Drying
Our efficient adsorption dryer solutions help you achieve low dew points with minimal energy consumption. Proper drying prevents corrosion, reduces microbiological risks, and stabilizes downstream processes.
4. Oil vapor filtration
Our activated carbon filter solutions effectively remove hydrocarbons and odors from your processes. This enables you to meet specific air purity standards for demanding applications. Our activated carbon filter solutions support your operational efficiency with exceptional service life and low pressure drop.
5. Testing and Validation
Continuous validation helps identify inefficiencies, detect integrity issues, and maintain process reliability. We support you with compressed air testing to ensure compliance with standards such as ISO 8573.
6. Sterile filtration
We supply validated sterile filtration solutions for critical applications. These Filter Elements reliably remove microorganisms and help meet hygiene requirements in industries such as the food, beverage, and pharmaceutical sectors.

Frequently Asked Questions About Compressed Air Treatment
Understanding compressed air treatment is essential for maintaining system efficiency and ensuring compliance with regulations. The following questions address common concerns regarding compressed air quality, system design, and operational challenges.
Why is compressed air treatment necessary?
Compressed air contains contaminants such as oil, water, and particles. Treatment removes these contaminants to protect products, equipment, and processes.
What standards apply to compressed air quality?
The ISO 8573 standard defines compressed air quality classes based on particle, water, and oil content. Systems are designed to meet these requirements. If you would like to learn more about the ISO 8573 standard, we recommend our technical article “ISO 8573-1 Guidelines on Compressed Air Quality for Food Production”.
How does moisture affect compressed air systems?
Moisture can cause corrosion, microbial growth, and process instability. Dryers remove water to ensure system reliability.
How can system efficiency in compressed air treatment be improved?
Optimized filtration, proper drying, and regular monitoring reduce energy consumption and prevent system losses. Monitoring and validation are necessary to understand the improvements in the systems. Our experts are happy to advise you on compressed air testing in accordance with ISO 8573 to ensure compressed air quality, or provide tips on system efficiency by reviewing each individual process step with you.
