Air compressor maintenance is crucial for optimal performance and avoiding premature repairs. Regular inspections and servicing of key components are essential, especially for rotary screw air compressors. Timely maintenance prevents minor issues from becoming major problems.
Atlas Copco is here to help from simple maintenance tips, a maintenance checklist till a complete service plan that fits your needs.
- Read the user manual
It is highly recommended that you read the user manual before you take any further steps. Always follow the instructions and follow the safety guidelines. In case of doubt, contact Atlas Copco
- Use Genuine spare parts
Each component of your compressor is vital for its overall performance, giving you the reliability, long lifetime and energy efficiency you expect. That’s why every Genuine part and lubricant is expertly designed, manufactured and tested according to the most stringent standards
To keep your compressor in good shape Atlas Copco’s genuine parts are the way to go.
- Regular Inspections
Air compressor systems have a series of processes that rely on one another to provide the desired performance. It comprises various components which must be maintained to ensure consistent proper functioning. It is considered best practice if you maintain a timely schedule for regular periodic inspections of your compressor to ensure that all its components are in optimal condition.
- Keep a maintenance log
An air compressor maintenance log helps track inspections, service history, repairs and operating hours in one place. Regular logging makes it easier to spot potential issues early and follow-up on maintenance activities. It also supports workplace safety and simplifies troubleshooting when problems occur.
- Have an issue? Check the troubleshooting guide
To minimize downtime, it's essential to have a solid understanding of common air compressor problems and how to resolve them quickly. A reliable air compressor troubleshooting guide can get you back up and running.
- Drain Compressed air moisture
Compressed air moisture is an inevitable byproduct that accumulates inside the air receiver tank in the form of condensate. Moisture also degrades the quality of output of industrial applications that the compressed air system is being used for. You need to make sure that you drain the air receiver tanks properly and from time to time for ensuring optimal performance and avoiding any damage. Another option is to have an automatic drain installed on the compressor.
- Change the air filters
The filter in an air compressor traps a lot of junk particles throughout the usage cycles. Air filters are designed to have a heavy load of particles, but it eventually reaches their peak. To keep a clean filter is to ensure that your air compressor performance does not degrade over a period of time. It is a good practice to keep a consistent check over the air filters and change them annually or if sandstorm conditions occur before the annual change.
- Change the lubricant
Oil-based air compressors need to be tended with care and the lubricant must be changed periodically to keep your compressor operating reliably and cost-effectively. Compressor oil protects rotating parts to avoid metal-to-metal contact. It absorbs the heat to ensure optimal working temperatures. It seals the clearances between the rotors and the housing, preventing air backflow and reduced output. Always ensure that the oil levels are maintained to the correct level.
- Replace the oil separator elements
Oil-lubricated air compressors rely on oil mist that helps smooth functioning. The compressors disperse oil within the machine in tandem with the air. However, before final delivery, the oil gets extracted from the air with an oil separator. Over continuous use and delivery, the air can get contaminated with oil if the oil-separator starts malfunctioning. It is imperative that you regularly inspect and change if required the separator elements for an optimally performing air compressor and to guarantee the quality of the compressed air output.
- Replace the oil filter
The oil filter captures dust, deposits and other foreign particles, ensuring a clean oil flow to the compressor element. Apart from protecting the bearings and other mechanical components, it prevents premature clogging of the air/oil separator. Timely replacement is needed.
- Inspect hoses and connections
Checking hoses and connections during air compressor maintenance is essential because leaks, cracks, or loose fittings can reduce air pressure, waste energy and put extra strain on the compressor.
Routine tasks like checking oil levels, draining condensate and replacing filters are typically safe for do it yourself maintenance. However with the service plans offered by Atlas Copco, your machine will maintain the highest operating standards. Regardless of the service level you opt for, our expertise streamlines the process, ensuring accurate timing for maintenance and swift procurement of the necessary components, all without any hassle.
Why does my compressor need maintenance?
Regular air compressor maintenance is essential to ensure reliable performance, efficiency and long service life. After a period of operation, your compressor requires scheduled servicing, and factors such as dust, temperature, and humidity can significantly influence maintenance intervals and the components that need replacement.
Performing timely maintenance with genuine parts helps extend the lifespan of your compressed air system, reduces the risk of costly breakdowns, and ensures high-quality, clean compressed air output.
To achieve the best results, we recommend using genuine Atlas Copco compressor parts, which are specifically designed to meet the highest standards and eliminate the risks associated with non-genuine alternatives.
Can I perform air compressor maintenance myself?
Yes, basic air compressor maintenance can be done yourself, as long as you follow the correct procedures.
Routine tasks like checking oil levels, draining condensate, and replacing filters are typically safe for DIY maintenance. However, to keep your compressor running efficiently and avoid damage, always follow the manufacturer’s maintenance recommendations.
If you plan to handle maintenance yourself, make sure you:
- Use certified, appropriate tools
- Keep spare parts well-organized and properly stored
- Have basic training or knowledge to perform tasks safely
For complex repairs or advanced servicing, it’s best to consult a qualified technician.
Which maintenance jobs should always be carried out by a qualified Service Technician?
Your in-house maintenance team can handle most routine, basic maintenance, but certain tasks should always be performed by a qualified compressed air specialist. These include:
- Replacing motors
- Diagnosing and repairing mechanical failures
- Moving or relocating large or heavy compressor equipment
- Conducting safety shutdown inspections
- Carrying out any compressor-specific maintenance your team is not formally trained to perform
It’s also important to note that incorrect maintenance can void your warranty, meaning you may not be able to submit a claim if a breakdown occurs due to improper servicing.
What oil should I use for my air compressor?
Selecting the right compressor oil is essential for maintaining performance, efficiency and long service life. Using the wrong oil can increase wear, lower efficiency and lead to costly failures.
To make the right oil selection, there are several selection criteria to take into account:
- Temperatue
- Air Quality
- Humidity
This guide outlines the key factors to consider when choosing the appropriate compressor oil..
