Compressed air is a critical power resource in most manufacturing and process environments. A good and proper compressed air system can offer effective plant operation and energy savings that increase profitability and productivity. Poor compressed air not only detrimental to the process quality, but also affect significantly on the costing due to wasted energy, down time in production line and heavy repairs to equipment damaged by polluted air.

In today's modern production facilities, the use of compressed air is often pivotal to manufacturing processes. Irrespective of whether the compressed air comes into direct contact with the product or is used to automate a process, provide motive power, package products, or even to generate other gases on-site, a clean, dry, reliable compressed air supply is essential to maintain efficient and cost effective production.

The three major impurities in compressed air are solid particles, water and oil. They influence each other (e.g. solid particulate agglomerates in the presence of oil or water to form larger particles, oil and water form an emulsion) and are sometimes deposited or condensed (e.g. oil vapour or water vapour) inside the pipework of a compressed air system. Other contaminants are also considered, including microbiological organisms and gaseous contaminants.

The Objective of compressed air quality testing is to:

• Establish the baseline quality of the compressed air use for process/production line.
• Investigate and determine the source of compressed air contamination along compressed air line system.
• Assess the efficiency and effectiveness of the compressed air filtration system to facilitate periodic maintenance program.
• Prevent any unforeseen and undesirable production losses due to down time and product quality issue.

Testing parameters including the following:

• Particle Counts Measurement
• Dew Point Measurement
• Oil Mist Testing
• Total Hydrocarbon Testing
• Total Particulates Testing
• Molecular Acids Testing
• Molecular Bases Testing
• Total Volatile Organic Compounds Testing
• Microbial Study
• Other parameters as requested by Client.
