Compressed Air Quality Analysis

In today's modern manufacturing facilities, compressed air is a vital energy source and is utilized in most manufacturing process. A good and proper compressed air system can offer effective plant operation and energy savings that increase profitability and productivity. However a poor compressed air system not only detrimental to the process quality, but also affect significantly on the costing due to wasted energy, leaking and down time in production line and heavy repairs to equipment damaged by contaminated air.

The use of compressed air is often pivotal to production processes. Irrespective of whether the compressed air comes into direct contact with the product or is used to pneumatic tools, provide motive power, cleaning, packaging and even printing. A clean, dry, reliable compressed air supply is essential to ensure trouble-free operation and maintain efficient and cost effective production.

The common 3 major impurities present 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.

ANOX is introducing on-site compressed air quality testing services to serve major compressor supplier and commissioning contractor as well as industrial end users. The service is designed to measure and remedy the often-hidden impurity that can gradually grow within compressed air systems and end up costing large amounts in wasted energy, defected products and repairs to equipment damaged by polluted air.

Objective

  • 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.
