Air Quality Check for compressed air systems

Ensure reliable compressed air quality—verified and documented.

Why compressed air quality matters

Compressed air is a critical utility in many industrial processes. Its quality directly affects product quality, process reliability, and operational efficiency. However, contamination by particles, oil, or moisture is often not visible and can remain undetected over long periods.

Uncontrolled deviations can lead to:

  • Product contamination and quality issues
  • Process disruptions and unplanned downtime
  • Non-compliance with required air quality standards (e.g. ISO 8573)

Air Quality Check under real operating conditions

Compressed air systems are subject to changing environmental and operating conditions, which can cause fluctuations in air quality over time. If the required quality is not consistently maintained, this can lead to process disruptions, product contamination, or unplanned downtime.

The Air Quality Check verifies whether your compressed air meets the requirements of your application and relevant standards such as ISO 8573. It provides transparency about the current condition of your system and helps identify deviations and potential risks at an early stage.

All measurements are carried out by qualified service technicians in accordance with ISO 9001 quality management standards. Over a defined measurement period, relevant parameters are recorded and evaluated to ensure reliable results and a solid basis for further action.

What the Air Quality Check includes

  • Measurement of relevant parameters

    Precise measurement of particles, oil content, and humidity to assess air quality.

  • On-site expert analysis

    Evaluation by qualified service technicians directly at your system.

  • Standards-based evaluation

    Assessment according to applicable standards and system requirements.

  • Clear documentation

    Structured reporting with transparent results and actionable recommendations.

  • Early detection of deviations

    Identification of contamination and risks before they affect operations.

  • Verification of compliance

    Confirmation that required compressed air quality standards are met.

Service options

  • Air Quality Check Basic

    The Basic measurement is designed to provide an overview of compressed air quality within a defined measurement period. Due to preparation and warm-up time of the measurement equipment, the total time required for a Basic measurement is typically one working day.

    The measurement results are documented in a compressed air quality report for a representative measurement period.

  • Air Quality Check Professional

    The Professional measurement evaluates compressed air quality over a longer period of time. This allows short-term deviations from limit values to be detected and analyzed in order to identify potential risks within the compressed air system.

    The Professional measurement includes additional operating parameters such as flow rate and temperature. The total measurement time is typically two working days, during which the compressed air system is observed under continuously changing operating and environmental conditions.

Air Quality Check Basic

Typical parameters measured include:

  • pressure dew point
  • particle concentration
  • residual oil content (vapor phase up to 16 bar)
  • oil aerosol / vapor concentration
  • system pressure

Calibration for reliable measurement results

Regular calibration is essential to ensure accurate and reliable measurement data. Over time, sensors and measuring devices can drift, leading to incorrect results and misinterpretation of system performance.

Professional calibration ensures precise and reproducible measurements, supports compliance with quality standards, and provides a reliable basis for system analysis and decision-making.

Calibration and system analysis are particularly recommended in the following situations:

  • Changes in compressed air quality
  • New or stricter quality requirements
  • System modifications or extensions
  • Unclear causes of failures or inefficiencies
