Maintaining your peace of mind

Air Compressor Maintenance 

Let’s face it. At some point, no matter how high quality the product is, equipment or machinery will break down. Breakdowns can have major impacts on the efficiency of your production which in a worst-case scenario, can cost your business thousands of dollars. While breakdowns are inevitable, regular and professional air compressor maintenance assures the reliability and quality of your equipment.

So why should I invest in maintenance?

With regular maintenance, you lower the risk of your compressed air system breaking down which ultimately leads to lower profitability. Think of your air system like a car being serviced. Filters and fluids are replaced, cooling water is inspected, belts are adjusted, and leaks are identified and repaired. These regular checkups ensure your compressed air system remains reliable throughout its lifetime.

Without servicing, system integrity could be compromised when undetected problems deteriorate, leading to damage. At some point, this will cost you a lot to repair.

Can’t I just pay for maintenance when I need it?

Sure, but keep in mind that you’ll have to closely monitor your compressor’s service requirements and order each service separately. A slow procurement process can lead to a delayed service which potentially means an increase in overall costs.

What are the risks of delaying my maintenance checks?

Most parts within your compressed air system have a specified lifespan. Failure to replace them on time can impact your compressor’s overall efficiency and reliability. Not only does this increase ongoing production costs but also the chance of a breakdown occurring which can have an even bigger impact on profitability.

How do energy costs affect my budget?

The biggest part of the total cost of ownership for compressed air equipment is energy consumption. If you fail to properly maintain your air compressor system, pressure drops may occur, decreasing the system’s efficiency.

During an average compressor’s lifetime of around 10 years, the cost of compressed air is roughly divided up as 73% energy costs with the remaining 27% divided between capital costs, installation and maintenance. In reality, producing 1 kW of compressed air requires 8 kW of electricity. So, if you’re not evaluating the energy performance of your system, you are potentially converting your money into thin air.

How often should my receiver be inspected?

Under the Occupational Safety and Health Regulations 1996 requirements and AS/NZS 3788:2006, routine biennial inspections of pressure vessels is mandatory. 

Pressure vessels used in the workplace present a lot of potential dangers when not properly maintained which can cause damage to property, injury and even death. This is why it’s essential to properly install and service receivers and ensure that all of your equipment complies with the relevant AS standards and Worksafe WA regulations.

Do I have to register my receiver?

As per the Occupational Safety and Health Regulations 1996 along with AS/NZS 3788:2006, registration of pressure vessels is mandatory in order to assess safety and to detect any dangerous deterioration.

Making the right choices when choosing your Compressor System

 

A lot of careful planning goes into the decision to purchase an air compressor system. Buyers have to contemplate a variety of factors including the amount of air pressure needed, what type of system fits their needs and how much they are able to invest in a system.

If you don’t have the knowledge and experience that Nessco Pressure Systems has when choosing the right system, mistakes can be made when selecting what to buy which can cost you in the long run. 

Let us help you out by pointing out some of the things to look out for when selecting your compressor system.

 

SIZE

Deciding on the correct size of compressor is key to the efficiency of your business. The wrong size can lead to problems with production and wasted energy which can increase overall costs. It’s also wise to plan ahead and think what may be your needs in the future.

Pressure

One of the key determinants to selecting size is the amount of pressure required. Your air compressor has to be able to provide enough air pressure so that you are able to complete the task at hand. Anything less will not work, rendering your system useless. This is why it’s important to know the pressure that is required beforehand so that you are able to choose a powerful enough compressor.

Air Flow

Another important factor to consider is the correct air flow needed for the compressor. To put it simply, flow is the ability of the compressor to perform a task within a given time period. The amount of flow needed is determined by the length of time required to complete the task. If your flow isn’t sufficient enough, your compressor will need to build up pressure inside its reserve tank which suggests that the compressor you’ve chosen might be undersize. Again it’s important to know your requirements before making a choice.

One of the best ways to figure out the correct flow needed is to perform a compressed air audit which can be conducted by our knowledgeable NPS staff.

Future Expansion

It’s also important to consider what your air usage might be like in the future when making your decision. While your current air pressure needs might be small, a company that plans ahead and selects an air compressor that will account for the growth of their business can save themselves a considerable amount by not having to purchase subsequent compressors systems.

 

TYPE

The type of compressor your business needs is another factor you need to consider at decision time. Two of the more popular options available are piston and rotary screw compressors.

Piston Compressor

The piston compressor is one of the most economical options available. This is a small and robust air compressor that is often used in small workshops, tire shops or manufacturing facilities. One of the highlights of the piston compressor is that they are relatively easy to maintain and usually require minimum investment however this doesn’t mean you should buy one this instant!

Piston compressors are designed for intermittent use which means it can only work about 50-60% of their duty cycle. These units also need time to cool off between their cycles otherwise they will overheat and fail. Another factor to consider is that piston compressors can be extremely loud when operating, so you may want to take into account whether any employees will be working close by.

Rotary Screw Compressor

The rotary screw compressor is designed for operations that require a constant compressed air supply. While piston compressors may only need to be in use for 50% of their duty cycle, rotary screw compressors may be used up to 100% of their duty cycle and are generally built to have long, reliable lifespans. The amount of popularity for screw compressors means there are plenty of options available which suit a range of budgets and needs.

The Huge Impact of Laminar Flow

Laminar flow is an integral component of compressed air efficiency.

 

Believe it or not, laminar flow is controlled solely by the airline used in a compressed air system. To fully understand the effects of laminar flow in a compressed air system, we need to explain exactly what it is.

Fluids & gases are unique in their ability to travel. Unlike solid molecules that remain stationary whose molecules tend to join others of the same kind, fluid molecules aren’t so picky. Fluid molecules, such as gases and liquids, partner with different molecules and are difficult to stop.

Candle Smoke Laminar FlowLaminar flow describes the ease with which these fluids travel; good laminar flow describes fluid traveling as straight as possible. On the contrary, when fluid is not traveling straight, the result is turbulence, or a reduction in laminar flow. This is depicted in the image on the right; as the smoke comes off the candle, it is smooth and straight (this would be considered perfect laminar flow). As it travels away, the molecules display imperfect laminar flow.

Turbulent air flow essentially results in an inefficient compressed air system. This may not seem like a major concern; however, it has huge impacts on compressor efficiency. Fluid molecules bounce and circle within their path, causing huge energy wastage. In compressed air systems, this turbulent airflow results in pressure drop. How do you avoid this from happening? It all comes down to compressed air system design.

The design and material of the air pipe, as well as the positioning of elbows and joints, has a direct correlation to laminar flow and pressure drop. To avoid high energy consumption of your compressed air system, reducing pressure drop is key.

If your system is experiencing high pressure drop, your compressor has to work overtime to provide the required air pressure. When your compressor works overtime, it not only increases your maintenance costs, but also your energy bills.

Laminar flow works in conjunction with the “boundary layer”; this is the very first layer of compressed air that touches the wall of the pipe. Through the use of Infinity fittings, such as the Infinity Reducing tee, the air can travel down the dropper with ease, creating a smooth transition without disruption to the laminar flow.

Compressed Air Safety Tips

Compressed air can be extremely dangerous if not used in a safe manner.

 

To reduce the risk of injury, it is recommended that the following guidelines are considered and implemented:

1. Never apply compressed air to the skin or direct it at a person

Even air at a pressure of 15 psi can cause serious injury. Never use a compressed air hose to clean dirt or dust from your clothing or body.

2. When using compressed air for cleaning purposes, ensure pressure does not exceed 30 psi (per OSHA regulations)

Always use goggles or a face shield over approved safety glasses for this application.

3. Wear ear protection

Exposure to excessive noise can damage hearing. Noise reducing mufflers can be fitted to machines to lessen the noise health hazard.

4. Never crimp, couple, or uncouple pressurized hose

Shut off valves and bleed down pressure before making any hose connections.

5. Use heavy duty clamps and fittings made especially for compressed air hose

Use only the correct type and size of hose end fittings and connectors.

6. Never use frayed, damaged or deteriorated hoses

Always store hoses properly and away from direct sunlight. A hose failure can cause serious injury. Hose reels can decrease your chances of injury, as well as help hoses last longer.

7. When blowing compressed air through a hose or airline, ensure open end is held securely

A free end can whip and can cause injury. Open the supply valve carefully and ensure that any ejected particles are restrained. A blocked hose can become a dangerous “air gun”.

8. Keep compressors regularly serviced

Keeping up to date with your compressor’s servicing schedule ensures air quality is controlled, and reduces the risk of over pressure, and component failure.

9. Do not use air directly from a compressor for breathing purposes

Only do so if the system has been specifically designed for such purpose, and suitable breathing air filters and regulators are in place.

10. Isolating valves should be of the self venting type and designed to be locking in the “off” position

This ensures that air pressure cannot be applied accidentally while the machine is being worked on.
