Steps for a Compressed Air Audit and Its Benefits

If you run a manufacturing facility, you will be familiar with the compressed air systems in your facility. They probably take up a huge amount of your electricity bills and just like any other system, they need check-ups. This check-up on the compressed air system of your facility is formally known as a compressed air audit. This article is a nutshell about all the things that you need to know about these air audits.

Why you need these air audits?

  • Compressed air audit can help you produce less air and waste less of the air produced.
  • Air audits can help you scan your whole system and reduces leaks in the system.
  • An air audit gives you all the reports regarding the faults of the compressed air system and increases the peak production of your facility.
  • Apart from the compressed air system load, air audits also decrease the load and the wear-tear ratio of the compressed air system which also means a direct rise in the lifetime of the system.
  • And of course, getting a boost in production and lessening the damage always means saving your money.

The compressed air audit consists of essentially five steps which we will be explaining in a little detail below.

  1. Get to know your environment – By environment, I mean the site surroundings. You have to extensively examine the facility and get a detailed report of all parameters and conditions of the manufacturing unit.
  2. Measure the efficiency of the air system – Efficiency has to be measured taking all parameters like pressure, flow, temperature and vacuum into consideration. Efficiency is an important performance factor in the compressed air audit.
  3. Determine the system mechanics – Efficiency is just one part of it. You also need to find out and analyse the system from in and out. You need to be knowledgeable about the system so that you can find out its faults.
  4. Find out techniques to save the situation – You can start figuring out ways to fix the leaks and improve the performance of the compressed air system by reducing the energy consumption.
  5. Verify the after-results after improvement – Before you reach a certain decision, you need to analyse the results. Get the results verified again and again until you are absolutely sure that your applied methods are actually effective.

What type of air audits are there?

  • A Walk the Line compressed air audit involves a visual check-up of the system. This excludes all the hardware.
  • Data Logging is one step ahead of the Walk the Line check. This technique includes logging the data into results and gets a comprehensive result of your system.
  • AirScan audits are the compressed air audits that form full, explicit and informative check-ups – the most intensive one among all the procedures. This can also be subcategorised into divisions according to which function you want to focus on most like leak reduction, maintenance review or more.
