The quest for high quality compressed air – Three key steps

When it comes to compressed air, air quality is of the utmost importance. All compressors need to undergo regular servicing in order to deliver superior air quality and improve the functionality of both your system and its components. 

Plummer Compressors gets parts to service air compressors If you don’t implement some air quality controls, such as dryers and filters, then you will be at the mercy of both machine and environmental conditions. All air compressors draw in contaminated air, and most air compressors are fluid lubricated, so if nothing is done to manage what passes through to the compressed air network adverse contamination can result.


Dryers are the most effective and most common compressed air treatment item and there are a range of options depending on applications and requirements. Filters are also a vital component in order to produce the air quality level the compressed air system needs. If your compressor is running hot, then you are at risk of higher moisture and greater oil carryover. With a filter in the system then, at the very least, you have a control point to mitigate fluctuating network air quality.


The ISO standard 8573-1 is a really good reference point, as this is how treatment components are specified. For more information on this quality standard download our guide here. By talking to one of our compressed air experts, they can explain the ISO standard and through asking some pertinent questions, they will guide you to the right treatment level for your circumstances.


Implementing your own internal “housekeeping” checks is vital to achieving proper air quality. Your compressed air service provider is not usually on site regularly, so there needs to be someone who is onsite to take responsibility for checking that everything is running normally.


Plummer Compressors recommends the following checks: 

  • If your air receiver is after a refrigerant dryer, implement a daily check where someone cracks the drain valve – if it is not dry then you have a problem.
  • Have coalescing filters drain into a translucent bottle – if you glance at it periodically you will then notice if the bottle is suddenly full or rapidly filling.
  • Create a logbook for the checks – this helps to make sure the checks do occur, plus there is then a record of what is normal when someone new completes the checks.  Click HERE to contact us for free assistance in creating a log book specific to your system.


Once you have internal housekeeping protocols to follow, there are key steps you can implement to ensure you are producing the correct air quality for the applications you are running. Examples of air applications range from plant air – used to power pneumatic tools; process air, found in pharmaceutical and food industries; and breathing air which is used in spray painting and hospital air systems.

The three key steps that we recommend to take for ensuring the appropriate quality compressed air are as follows: 

1. Determine what air quality level you need – What uses compressed air? What is the impact of water, oil or dust contamination for those users or contact points? Air quality is split into class ratings that cover the three main contaminants: oil, water and solid particles.

2. Talk to an expert who can assess whether your current treatment components meet that need. Ask site staff whether there have been any historical problems – as this may also identify any treatment weaknesses.

3. Install any changes and then implement your own set of checks (so you know the system is working) – as was outlined above.


The current economic climate means we are all facing new business challenges. Compressed air is generally an essential utility – if it stops, production stops. While cutting equipment maintenance in testing times may seem like a good idea in the short-term, it may be a choice that is regretted if it stops your entire production and results in larger resultant losses. 

Air quality requirements vary from business to business but making sure you are producing the correct air quality for your applications needs to be a high priority, particularly if you want to do it in an efficient and cost-effective manner.

The True Cost Air Leaks Have on Your Business

Compressed air is an essential utility for most manufacturers and factories and many of our clients wonder ‘what the true cost of compressed air is?’

The most expensive element in the total cost of compressed air—including set up costs, servicing and maintenance, is the power consumption. In fact, over the lifespan of an air compressor, power typically costs ten times that of the purchase price of the compressor. 

Did you know?

Air leaks are a common cause of wasted compressed air, in fact 20%-50% wastage through leaks is not uncommon. This is therefore a significant source of wasted power. Consequently, proactive leak detection and repair can generate substantial savings. Most experts agree that the “low hanging fruit” of compressed air system efficiency improvements is leak management and reduction.

If the electricity cost to generate compressed air is $35,000* annually, then you could be wasting up to half of that – or $350,000 over the life of your compressor!

It is vital to have knowledge about your compressor – this means you will understand the air compressors capabilities and whether it is or isn’t functioning normally.  If you are unsure what to check, please ask your service provider to give you some training.

To ensure a longer life span of your air compressor and save you costs, maintaining a regular service history will help you significantly to reduce wasted costs daily. A compressor system that is for example, medium sized could potentially save you between $10,000 and $30,000 per year!

All this information begs the question ‘what is a good leak prevention program to save costs?’

We recommend that all manufacturers and factories with compressed air systems should ideally establish a proactive leak reduction program. An air leak prevention program could be part of an overall program aimed at increasing the efficiency of compressed air systems. Additionally, once leaks are detected and fixed, the system should be re-evaluated. 

Our approach to this is transparent: 

  1. Detection & tagging, 
  2. Quantify & prioritise,
  3. Repair leaks – according to priority. 
  4. Repeat from step 1!

A well-established compressed air system ‘leak repair program’ is fundamental in maintaining the efficiency, reliability, stability and most of all cost effectiveness of any compressed air system.

Keep in mind that maximising energy efficiency on a long-term basis WILL save you money, whilst contributing positively to our environment.
