Whether it's used for packaging, manufacturing, or even breathing applications, the quality of compressed air must be validated to ensure safety, purity, and compliance with international standards like ISO 8573.

Why Compressed Air Validation is Important

Compressed air can become a source of contamination if not carefully monitored. It can carry moisture, oil, particles, and harmful gases, which can compromise product quality and safety.

• Protects product integrity

• Meets regulatory and audit requirements

• Prevents microbial and chemical contamination

• Essential for cleanroom and critical process environments

Key Parameters Tested in Compressed Air Validation:

1️⃣ Dew Point

Indicates the moisture level in compressed air. A low dew point ensures the system remains dry, preventing corrosion and microbial growth.

2️⃣ Particulate Matter

Contaminants such as dust, rust, and other solid particles may be found in compressed air systems. Testing ensures particle levels are within acceptable limits, especially for cleanroom use.

3️⃣ Oxygen

In breathing air applications, oxygen levels must be carefully measured to ensure they are safe for human inhalation.

4️⃣ Gaseous Impurities

Air is tested for harmful gases such as:

Carbon Monoxide (CO)

Carbon Dioxide (CO₂)

OIL MIST Nitrogen Dioxide (NO₂)

Sulfur Dioxide (SO₂)

These gases can be toxic or reactive and must be within permissible limits.

5️⃣ NVPC (Non-Viable Particulate Count)

Non-living particles in the air are counted and analyzed, especially in sterile manufacturing environments.

6️⃣ Oil Content

Oil aerosols and vapors from compressors can enter the air stream. Testing ensures levels are low to avoid contamination of products and equipment.

7️⃣ Moisture/Water Content

Moisture can promote bacterial growth and harm delicate equipment. Maintaining low moisture levels is essential for both operational safety and system efficiency.

8️⃣ Nitrogen

In some systems, nitrogen is used instead of or along with compressed air. The concentration and purity of nitrogen are validated to meet specifications.

9️⃣ Viable Count (if applicable) Microbial analysis checks for live organisms in the compressed air, especially in sterile and critical environments. This testing is typically carried out internally or at the client's request.

Standard Followed:

ISO 8573 – An international standard that specifies the required purity levels for compressed air in various applications.

GMP/WHO guidelines – For pharmaceutical and healthcare sectors

OSHA/NIOSH standards – For breathing air applications
