How to Avoid Pressure Loss

Our guide to efficient compressed air lines

Poorly designed air lines can often lead to low productivity, poor air tool performance, and an increase in energy bills. Therefore, the layout, installation and maintenance of your Infinity pipe system are crucial to keeping your business running.

When designing a compressed air line, it is essential to know what factors have an impact on pressure efficiency;

  1. Pipe Sizing
  2. Piping Layout
  3. Maintenance

Pipe Sizing

When constructing a compressed air line, you need to correctly scale the piping to prevent excess or a drop in pressure. Pipes that are too small for the capacity of airflow may increase the pressure past the safe point of the end-use application. Increasing the pipe size helps reduce pressure drop, maintains safety measures, and adds to the air lines capabilities.

Under-sizing the internal diameter of the pipe, relevant to the flow required, will increase the velocity. Higher velocity in pipe systems can be a significant cause of:

  • Erratic pressure control
  • Turbulence in the pipe system
  • Pressure drops
  • Extra power requirements at the compressor

Piping Layout

Piping layout maps the path compressed air will take around the workplace. Design is critical to efficiency; as the more bends you have in your line, the higher the pressure drop will be.

A ring main system is considered a best practice. As the air flows in two directions, the volume of compressed air carried in each direction is reduced by up to half, in most cases. Once the ring main has been installed feed lines can then run to feed required production areas and end-use applications as a subnetwork.

Compressed Air Ringmain System


Regular maintenance to your compressed air line helps prevent future problems.

Simple steps such as shutting your compressed air off for nights and weekends, and regularly checking the drains can help prevent long-term wear and tear. Changing the filters periodically helps to ensure optimal performance.

Beware of the Hose Whip

Providing a safe working environment is essential, especially when using pneumatic tools and compressed air.

Many injuries are caused in factories and workshops by hose whip when the compressed air line is disconnected or bursts while still under pressure. The injury can be caused by the thrashing hose itself or blowing debris. The whip will continue to happen until the pressure is restricted.

There are a couple of ways to reduce the risk of hose whip;

1. When an incident starts, compressed air fuses engage and decrease the flow of air into the hose, allowing the pressure to equalise and stop the whip before it begins.

2. Shutoff valves are installed at the compressed air source and are set to a specific pressure cap. If the pressure reaches the limit, or the hose is damaged, the valve shuts off the airflow automatically.

How to Prevent Hose Whip

  • Here are a few preventative measures you can take to reduce hose whip occurring:
  • Check the connections whenever setting up air hoses to make sure they are secure
  • Always hand tighten valves, regulators, and connections
  • Never modify the nozzle
  • If a hose breaks or becomes disconnected, immediately get out of the way
  • Never attempt to grab the hose and control it; this is a common cause of injury
  • Avoid sharp bends in the hose, which can damage the reinforcement

Watch the ROSS AIR-FUSE in action. It senses a broken hose and automatically reduces flow to minimise hose whip

Benefits of Choosing Infinity Aluminium Pipe for Compressed Air Systems

Did you know aluminium piping was initially introduced in the late 1980s as a smarter alternative to plastic and steel pipe in compressed air systems?

Traditionally, engineers have specified a variety of piping materials for compressed air systems, including, but not limited to galvanised steel, stainless steel, copper, and even PVC.


Many companies have made the switch to the industry standard for compressed air – Aluminium Piping. However, many of the benefits associated with an aluminium system are lost with the addition of plastic fittings.

Reduced costs and increased longevity are just two of the many advantages of using aluminium piping to install a compressed air system.


  • Up to 50% savings in labour, since the aluminium pipe is supplied ready for use
  • Infinity pipe is lighter than steel or copper alternatives, reducing installation and modification costs
  • Infinity piping doesn’t require threading, soldering or unique skill sets
  • No special tools, or preparations besides cutting and deburring required
  • A compressed air system built with Infinity piping is much cleaner than air delivered by a steel pipe system.
  • Infinity pipe’s corrosion-resistant properties offer optimal airflow, reduced energy costs, and better air quality overall. \


Operating in the compressed air industry for over ten years, Infinity Pipe Systems can supply, design and build a full aluminium piping system based on maximum optimisation and safety.

We will work closely with you to create a customised compressed air plan that ensures reduced energy costs, minimal maintenance and allowance for future expansion.


Compressed Air Line Safety



How to Work Safely with Compressed Air Lines

In recognition of National Safe Work Month this October, Infinity Pipe Systems has compiled a list of handy hints and important safety precautions to consider when working with compressed air lines.

  • Only OEM fittings should be used on air lines.
  • Air lines should be inspected frequently with any defective equipment repaired or replaced immediately.
  • Compressed air lines should be identified as to maximum working pressures (psi), by tagging or marking pipeline outlets.
  • All pipes, hoses, and fittings must have a rating consistent with the maximum pressure of the compressor.
  • Operators should avoid bending or kinking air hoses.
  • Air hoses should not be placed where they will create tripping hazards.
  • Air hoses should be kept free of grease and oil to reduce the possibility of deterioration.
  • Hoses should be checked to make sure they are properly connected to pipe outlets before use.

Ross Lockout L-O-X Valves

Marking pipes can help make the workplace safer and more efficient. When pipes are clearly
labelled, fewer accidents involving injuries and damage to property occur. Make sure workers can tell at a glance which pipes carry compressed air and which carry other gases or other liquids under pressure.

Because many companies use pipelines to carry many different substances, staff should be strongly aware of the Content Identification requirements of AS 1345-1995.

Our Infinity Project Management Team and Designers are committed to complying to Australian Standards and Good Work Design. With support documentation and proven competency, our staff is qualified to perform consultation, design, installation and maintenance support for any airline, Australia wide.


Choosing the Right Filters for Your Compressed Air System


One of the greatest lessons you could learn when it comes to compressed air distribution is to never underestimate the damage that can be caused by condensation and contamination. In order to maximise equipment lifespan and productivity, it is imperative that compressed air is treated based on an understanding of external conditions and the required application.

To provide the purest air quality possible, a combination of filters should be connected to the air-flow to capture these impurities before they contaminate the system. Infinity’s Air Preparation products allow you to select the type of filters that best suit your compressed air equipment and applications. Specific filters remove different things and have unique capabilities.

Included in the Infinity Industrial Pack:

1. Industrial Pre-Filter

Removes solid particles such as dust, pollen, mould and bacteria from the air.

2. Industrial Coalescing Filter
Traps and subsequently removes liquid, oil and water from the compressed air stream.

3. Industrial Absorption Filter
Absorbs smells, odours and tastes from compressed air, making it suitable and comfortable for breathing.

Compressed Air Systems Require Decent Air Filtration

Filters play a vital role in the compressed air process. Sanitary air impacts a number of different factors and elements regarding the performance, efficiency, and durability of various compressed air systems. By removing contaminants, compressed air filter systems protect the equipment and can actually extend the life of an air compressor system.

Effects of Contaminated Compressed Air

  • Rusting and leaking of compressed air lines
  • Pressure drop due to clogging and build up
  • Reduced efficiency
  • Increased costs

Types of air filters

  • Particulate filters – Used to remove dust and particles from the air.
  • Coalescing filters – Used to capture oil and/or moisture
  • Activated carbon filters – Remove odours and vapours.


What are the important factors to consider when choosing the right filter for your application?

Size: A filter for an air compressor is rated based on inlet flow, which is generally measured in cfm. Match the inlet and outlet pipe size of the filter assembly to avoid generating excessive pressure drop across the compressed air filter.

Extraction efficiency: Extraction efficiency refers to the filter’s ability to remove dust from the air.  You might be surprised to learn that a 99.8% filter will pass double the amount of dust that a 99.9% filter would.

Temperature: Filters have a maximum operating temperature. General use compressed air filters are designed for use at 38°C. It is a best practice to position compressed air filters in a location where the temperature is as low as possible.

Pressure drop: There is a pressure drop between the upstream and downstream sides of a filter. This is known as Delta P. You want a Delta P that is as low as possible when sizing a new compressed air filter and housing.
