Do you know that your hospital, manufacturing unit, pharmaceutical, petrochemical, medical, food and beverage industry requires a periodic compressed air testing service? It is important for plant operators to monitor the quality of compressed air in their processes. If you get the compressed air quality tested you can save unnecessary hurdles in the smooth functioning of your business.

Compressed air quality testing ensures that the air supplied to industrial processes is free of impurities that might damage the equipment or alter the quality of finished products.

Why is compressed air testing required?

A compressed air testing will ensure that the compressed air being supplied to industries should be routinely tested to ensure that it is free of impurities.

The contaminants which are water, suspended particles, and oil residue are generated from three major sources:
• Contamination from ambient air drawn into the compression system
• Impurities introduced from compressor parts and lubrication oils
• Inbuilt contaminants from piping and storage components of air compressors

Importance of compressed air quality testing

Compressed air testing is crucial in large industrial set up where high quality products are manufactured. The impurities in air quality could damage the costly equipment and final products. This is why it is crucial to follow the guideline of WHO and Factory act during all process cycles which requires compressed air usage.

Method used for sampling and analysis

The ISO 8537 compressed air standard is an internationally recognized system that applies to the purity of compressed air in an industrial setting. This testing protocol is both an efficient and cost-effective method of determining the level of impurity present in a pressurized gas sample.

Compressed air ISO 8573 testing schedules for particulate contaminants, water, and oil.
