Compressed Air Tests & Audits
Compressed air is a vital energy source and is utilised in many industries. Air tests are particularly important within areas of food production, pharmaceuticals and medical devices. Fed directly into the controlled environment, these lines are required to meet the same ISO classification as the clean rooms and spaces they serve. Since they may introduce contamination, the lines must be regularly controlled, monitored, and tested.
When treated properly, compressed air is regarded as a safe and clean utility when compared to other energy sources. However if regular air tests are not carried out, compressed air can become contaminated, jeopardising product sanitation.
Contaminants originate from three general sources:
- Contaminants in the surrounding environment are drawn into the air system through the intake of the air compressor. Ingested contaminants appear in the form of water vapour, hydrocarbon vapours, natural particles and airborne particulates
- As a result of the mechanical compression process, additional impurities may be introduced into the air system. Generated contaminants include compressor lubricant, wear particles and vaporised lubricant
- A compressed air system will contain in-built contamination. Piping distribution and air storage tanks, more prevalent in older systems, will have contaminant in the form of rust, pipe scale, mineral deposits and bacteria.
NPS are qualified and fully equipped to ensure your compressed air lines stay contamination-free. This service includes those who use respiratory protection. Did you know that it is a legal requirement to have your breathing air system tested on a regular basis?
Respiratory protection should comply with AS/NZS 1716 Respiratory protective devices, and used in accordance with AS/NZS 1715 Selection, use and maintenance of respiratory protective devices. NPS are certified to conduct air testing to ensure the quality of breathing air is in line with industry standards.
Air can often be viewed as an unlimited resource with no associated costs.
However, with compressed air accounting for as much as 20% of total electrical costs in industrial applications, over the life of a compressor the operational running costs far outweighs the cost of its yearly maintenance and initial purchase combined.
If you’re not regularly evaluating the energy performance of your system, you are potentially turning your money into thin air.
With energy accounting for 73% of your total compressor costs over 10 years, our compressed air energy audits will have a great impact on the running costs of your system, potentially saving you thousands of dollars annually.
