Air Kraft's Solutions for Compressed Air Contaminants

Why Contaminant Removal Matters

Compressed air isn’t just air in a smaller space; it carries contaminants like Particles, Moisture, and Oil. These impurities can affect the performance and lifespan of your machinery and tools.

What is ISO8573-1:2010

ISO 8573-1 is an international standard that specifically addresses compressed air quality. It provides guidelines and specifications for measuring and classifying contaminants in compressed air systems. Here’s a simplified explanation:

ISO 8573-1 is like a quality standard for the air we use in compressed air systems. It helps us understand and control the levels of contaminants, such as particles, moisture, and oil, present in the compressed air.

The standard divides contaminants into three main categories: particles, water, and oil. Each category has specific limits or levels that determine the quality of the compressed air. Let’s break them down:

  1. Particles: These are tiny solid substances floating in the air. ISO 8573-1 measures the size and number of particles allowed in the compressed air. It defines classes like Class 1, Class 2, and so on, where Class 1 represents the cleanest air with the fewest particles.
  2. Water: Compressed air systems can have moisture or water vapor, which can cause problems in various applications. ISO 8573-1 sets limits for the amount of moisture allowed in the compressed air. It uses a dew point temperature scale to determine the level of dryness required.
  3. Oil: Some compressed air systems use lubricants or have oil contaminants. ISO 8573-1 specifies the maximum allowable oil concentration in the compressed air. It uses different classes to indicate the acceptable levels of oil content.

By following ISO 8573-1, businesses can ensure that their compressed air systems meet specific quality standards. This helps prevent equipment damage, maintain product quality, and ensure the safety of processes that rely on clean compressed air.

If you need more detailed information or specific guidelines related to your application, it’s recommended to consult the complete standard or seek expert advice from Air Kraft Ltd


Compressed air can contain up to 140 million dirt particles per cubic meter. Our advanced filtration systems can help you tackle this issue effectively.


Water vapour commonly contaminates compressed air and poses a risk by corroding pipes and damaging expensive equipment like lasers and CNC machines. Our specialised dryers efficiently remove this moisture.


Oil can enter your compressed air system in two ways: from oil-lubricated compressors and external sources like vehicle emissions. Our filters can remove oil contaminants to ensure the purity of your compressed air.
