How Can Pressure Drops Cost You Money

Avoid unnecessary pressure-drops to save you money

Did you know that pressure drops and leaks are the two largest areas of energy loss on your air compressors? Itโ€™s easy to understand why a leaking pipe or fitting creates energy loss. Pressure drops are not quite as noticeable, since you cannot hear them.

What is a Pressure Drop?

According to Compressed Air Best Practices, โ€œPressure drop is a term used to characterize the reduction in air pressure from the compressor discharge to the actual point-of-use. Pressure drop occurs as the compressed air travels through the treatment and distribution system.โ€

Did you know that a small undersized filter would result in unneeded pressure drops in your system? Do not go for the cheap option because you will make up for that cost in energy consumption.

3 Most Common Reasons for Pressure Drops

The 3 most common reasons for unexpected pressure drops in your Air Compressor System. 1. Leaks 2. Improper sizing or maintenance of your Filters 3. Piping configuration

Suggestions To Help with Less Pressure Drops:

1. Unsure of your filter size? Go up a size. It will pay off in the long run.

2. Undersized piping can cause pressure drops. Make sure your pipe is large enough to handle your flow.

3. Reduce the distance the air travels through the distribution system.

4. Check for leaks! Air leaks can will result in using more power than necessary to supply compressed air & contribute to the system's air drops.

5. Increasing the size of your pipe, even from 2โ€ to 3โ€ ,can reduce pressure drop up to 50%. Shortening the distance that air has to travel can further reduce pressure drops by about 30%!

Did you know? Air leaks cause machines to cycle more frequently and by doing so can increase the running time of the air compressor. More running time leads to additional maintenance requirements and possible increased unscheduled downtime.

Remember, unnecessary pressure drops will result in poor system performance and excessive energy consumption. Any kind of flow restriction, whether it's a leak, poor piping configuration or a filter will play a huge role in a system requiring higher operating pressures than are needed, resulting in higher energy consumption.

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences.


The air dyer is one of the most ignored cooler in the system. A dirty condenser will cause water in the lines, or worse it will cause complete dryer failure.


Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line.


A question that is occasionally asked by our customers to Ash Air is 'what is the cost of compressed air?'ย  This article looks at the product costs involved with compressed air, as well as minimising the energy cost of compressors and cost allocation. When looking at these factors, we need to realise what causes dropped efficiency of your compressor, leading to increased costs of compressed air.
