Efficiency of Compressed Air Distribution and Piping

Think about efficiency for a minute. Every year with constant innovation, things are becoming even more efficient. Everything from electronics to industrial machinery are being developed to get more done faster while using less power.

The same is true for Air Compressors, having a compressed air distribution system that is inadequate will lead to higher energy bills, low productivity, and poor air tool performance. There are three main demands which must be addressed to avoid inefficiency.

  1. Low pressure drop between the compressor and the point of consumption
  2. Minimal leakage from the distribution piping
  3. If no dryer, making sure there is proper condensate separation

These demands primarily apply to the piping installation for current and planned compressed air consumption. Routing, design, and making sure you are using the proper dimensions for your compressed air piping is important for the efficiency, reliability, and cost of compressed air production.

Rather than increasing a compressors working pressure to compensate for large pressure drops, which can decrease efficiency, it is recommended to evaluate the fittings. The best option for optimal efficiency is designing a closed loop ring pipe system. Once installed, pipes can branch out and run to various consumptions points. This approach will provide uniform compressed air supply as air is delivered to the consumption point from two directions.

Setting up your compressed air system for optimal performance with minimal pressure drops and leakage is important for achieving ultimate efficiency and a great place to start is to look at your piping installation.

Oil Free - Screw Air Compressors

The team at AshAir specialises in oil-free or oil-less scroll compressors with zero risk of oil contamination, and are ideal for critical applications including medical, pharmaceutical, dental, R&D, food & beverage, wine and brewery. Our 100% oil-less scroll compressors are designed with fewer moving parts, which means less wear and tear, less noise, higher efficiency and reliability, and a longer machine life .

These scroll compressors use cutting-edge scroll technology where the spirals never contact each other, and no lubrication is needed, making them completely oil-free. Our SPR 20 Multi oil-less scroll compressor operates with variable air delivery, controlled by an intelligent controller for air delivery supplied according to the fluctuation of air demand. This means a higher energy efficiency and more stable system pressure.

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?'  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.
