Compressor Servicing FAQs

Taking Out The Guesswork Out Compressor Servicing

  • We understand that the daily running and operations of your facility will take precedence, often resulting in compressor servicing taking a back burner
  • This is why we aim to provide you with all the information you need to take the guesswork out of Gardner Denver compressor servicing to ensure complete peace of mind
  • Below are some of the questions we’ve found are the most frequently asked

Servicing & Replacement:

Usually, servicing and maintenance intervals will depend on the operating time and hours of your system. However, even if your air compressors don’t reach their operating hours within a 6 to 12 month period, or until the next recurring maintenance, they will still require a service. This is down to the wearing of parts, oil and filters, which are subject to a sustained ageing process. To ensure trouble-free operation and guarantee operational safety, it’s recommended to observe the specified maintenance intervals depending on the type of plant. As a general rule, though, the minimum interval for compressor servicing is once per year.
This entirely depends on the type of filter element and its function. Generally speaking, though, all filter elements should be changed every 6 or at least every 12 months.
Regardless of the filter type or function, regular replacement is crucial to ensure the continuous delivery of high-quality compressed air and to reduce energy costs caused by inefficient filtration equipment.
An oil change and recurring maintenance will often go hand in hand. However, the exact oil change requirement will ultimately depend on the type of compressor oil you use. For instance, mineral oils should typically be changed every 4,000 operating hours, whereas synthetic oils usually last twice as long. You will also need to consider the installation and suction conditions as these factors may cause oil change intervals to vary. If you’re in any doubt about the interval best for your compressor and oil, we’d recommend having the condition of your oil laboratory tested, using a comprehensive oil analysis and check.
This is a commonly debated question, but in principle, a compressor oil that has been approved by the plant manufacturer is the best bet and must be used. Compressor oil, for oil-lubricated screw systems is a vital component, and must cool, compress and lubricate. However, it also needs to be separable afterwards. Depending on your application or process, mineral, synthetic or food grade oils can be used.
In an oil-lubricated screw air compressor, the compressor airend is often subject to bearing wear due to the nature of its design. The bearing manufacturers specify an approximate running performance of 35,000 operating hours for their bearings. Therefore, we’d recommend the preventative exchange of bearings once this number of operating hours has been reached.
Although the year of manufacture is often thought to dictate a compressor's lifetime, it is actually more associated with its operating hours. Therefore, it’s difficult to quantify a service life accurately. Due to technical progress and subsidy programmes, it should instead be examined whether replacing an older compressed air system can yield economic and ecological benefits. This value may alternatively be achieved by modifying and altering existing systems, for instance, by replacing with energy-efficient electric motors or retrofitting a heat recovery system.

Servicing Agreements & Monitoring:

Every compressed air system is unique, and will have unique features and requirements. It is possible to obtain a service agreement for all of these requirements and determine the scope of the servicing agreement yourself. In this way, together, we can ensure that operating costs and operational reliability are guaranteed.
Yes! For all air compressors, we offer the iConn compressor services, which monitors the operating conditions of all compressors, thus enabling intuitive 24/7 monitoring of your plant.

Energy Saving:

Heat recovery is an effective way to increase energy savings by capturing, recycling and reusing the heat created by the compression process. Generally speaking, a heat recovery system can be retrofitted to an old compressor. However, it is typical that the design must be agreed upon to ensure optimal efficiency and safety.
Ecologically, it’s always sensible to switch off any unnecessary energy consumers. However, when it comes to refrigeration dryers, it should always be remembered that the dryer capacity is not immediately available after the dryer has been switched on. Refrigerant dryers need a pre-run to cool down their system. The time for this varies from dryer to dryer, so as a precaution, the refrigerant dryer should be switched on half an hour before the compressor starts. The air dryer should remain switched on permanently if it cannot be started in time. This is because the costs and energy required to remove the condensate from the piping system far exceed the possible savings by switching off the refrigeration dryer.

General Questions:

Heat is a natural by-product of the air compression process. Therefore, the release of heat during compression heats up the air, the oil, and, as a result, the tank.
This is entirely dependent on a couple of factors, including pipe diameter, conditions and material. For more information, check the specifications on https://www.gardnerdenver.com/en-gb/compressors/epl-piping or the pipe manufacturer’s specifications
It should always be considered that compressed air can be dangerous and should, therefore, be used with appropriate caution. Even really high-quality compressed air equipment can have risky defects if handled, used, or maintained incorrectly. Since the air is under high pressure, there is a risk of sudden decompression in the event of a defect.
If the vessel of a compressor needs to be welded, the welding process must be performed by an ASME-certified welder, as all pressure vessels supplied by Gardner Denver are certified. ASME-certified welders must, therefore, also carry out any welding work on these vessels.
By design, air compressors compress the ambient air. Whilst electrically powered air compressor do not produce carbon monoxide when they operate, they may suck in and compress it, if it’s present in the ambient air. If you have any concerns about carbon monoxide, it’s best to always check the applicable regulations.
When an air reservoir contains compressed air, it will weigh more than if it were empty. As a general rule, you should never work on or move any compressed air equipment that is connected to the power supply, or under pressure.
