Oil and Oil Filters
Protect your compressor, with the right air compressor oil filter, and save money on expensive repairs.
What does an air compressor oil filter do? They filter the oil to remove any dirt and dust. In other words: they protect your compressor from damage by contaminants. Dust and dirt will damage the filter element, wear the bearings and clog the oil-separator.
High quality oil filters are recommended to conserve this oil and also to protect other parts of the compressed air system. Just as with air cleaners and air/oil separators, the oil filters in a compressed air system are also part of a process chain, in which the weakest link can seriously lessen the performance of the whole system. If the oil filter does not work properly, the dirt deposits will negatively affect the air/oil separators, fine filters and machine components. The result is a considerable shortening of the filter service life and increased maintenance costs for the compressor.
Why Is It Important to Change Oil?
Oil performs a vital function for an air compressor. This specially formulated oil acts as a cooling, lubricating and sealing agent during compression. The lack of oil can lead to quick heating of your air compressor which, in many compressor models, causes an automatic shutdown. Thus, having the necessary amount of the correct grade oil allows your compressor to perform much longer.
Since compressor oil also acts as a sealant, its absence can cause leakage which greatly reduces its efficiency and the maximum pressure it produces. Moreover, the oil serves as a lubricant that prevents the wear and tear of compressor parts.
How Often Should We Change Compressor Oil?
The frequency at which one should change the oil in an air compressor heavily depends on the type of compressor you bought. Some compressors may need oil to be changed more frequently than others. The best source of information about this is found in the user’s instructions manual that comes with the compressor oil package you have purchased. Some instructions manuals even provide information about the expectancy life of the oil in terms of service hours.
If you are unable to locate your user’s manual, there are some basic guidelines for compressor oil changes. For Screw & Vane Compressors – Typically change standard oil every 2000 service hours. Some manufacturers offer an extended service life oil.
As mentioned, the need for oil change in an air compressor varies according to its model and service hours. At the least, you should change the oil in your air compressor once a year.
What Type of Compressor Oil Should Be Used?
Just like in oil change frequency for air compressors, it is always best to follow the recommendations of the manufacturer. Not only will it work best for your compressor, but it will also ensure that your warranty is not voided. When you are uncertain of what to use, especially when the user’s manual is nowhere to be found, Air4U Group can advise the correct oil for your machine.
Compressor oil is specially formulated for compressors, using motor oil or standard hydraulic oils can have a detrimental effect on your compressor performance and life cycle
Some compressor owners are also torn between using synthetic or standard air compressor oil. Both can be used if your manufacturer allows it, otherwise, it is best to stick to what is recommended to avoid voiding your warranty.
Standard air compressor oil is best for compressors that are not heavily used.
For heavy duty compressors like those used in construction areas or large industries, a synthetic compressor oil is more recommended. This type of oil can best protect the compressor from overheating and has a wide range of temperature suitability for colder environments. Many compressor users also say that synthetic compressor oil causes the compressor to run smoother and more quietly.
Where to Buy Compressor Oil?
To make sure that you are getting the best quality compressor oil, whether standard or synthetic, make sure to buy from trusted distributors. Air4U stock a wide range of oils suitable for most types of air compressors.
Caring for your compressor and doing necessary routine maintenance will help you save money in the long run. Air4U group can assist with preventative planned maintenance. For more information, please see our Blog about Maintenance and Service, https://www.air4ultd.co.uk/service-and-maintenance/
