The Low-Down on Compressor Lubricant
Compressors need lubricant for a variety of reasons. In fact, some may argue that the lubricant is the most important part in keeping a system running smoothly and efficiently. Choosing such an important element may seem daunting. However, the compressed air specialists at CASCO USA are here to help.
Both reciprocating and rotary compressors require specialized lubricant to run. Generally, synthetic or synthetic blends should be used, especially in the case of rotary compressors. Synthetic lubricants have longer life spans and yield better results. Whether you choose a full synthetic or a blend will depend on the specifics of your machine. However, you will never want to put regular motor oil or any sort of non-specific oil into an air compressor. Not only can the non-specialized oil cause problems, but it could even void manufacturer protections.
What is synthetic lubricant?
Synthetic lubricant is created by modifying mineral oil to better fit the needs of air compressors. Usually this modification process involves removing impurities found in the crude oil. The resulting lubricant can seal systems, prevent corrosion, and protect parts against wear. Using the right lubricant can even contribute to reducing energy costs, cooling oil temperatures, & maintenance needs.
Benefits:
Cleaner Machine Operation
Full synthetic compressor lubricant makes the system operation cleaner. There are less byproducts in the fluid and the risk of deposits decrease. With less residue left behind, the compressor does not need to work against itself. The result is a cleaner running system.
Synthetics also have higher flash points. A higher flash point both improves safety and reduces the risk of internal fires. Users should plan on a synthetic lubricant maintaining its properties longer and at higher temperatures than a mineral oil would. Though operating a compressor at too high of a temperature will impact the lifespan and efficiency of the lubricant. Always discuss operating conditions with a qualified compressed air engineer to design the best set-up.
Protection of Parts
Air compressors contain many internal parts that keep the system working. Using synthetics helps to protect these parts. The lubricant not only coats the parts, decreasing system friction & wear and tear, but also the special formula reduces rust and corrosion. The machine can continue to operate as it is supposed to without the fear of buildup causing problems. Synthetic lubricant prevents negative side effects such as damage, efficiency loss, or poor airflow. Instead, the system can simply run.
Cost Savings (Energy Savings)
Cost savings remain the best benefit of using proper lubrication. Both of the above benefits describe how a properly lubricated system requires less work to perform effectively. Whether through decreasing operation errors or decreasing friction between parts, there is simply less “stuff” for the machine to work through. As a result, operation requires less energy. A decrease in energy consumption leads to direct monetary savings.
The secondary way that cost savings appear are through a decreased need for maintenance. As mentioned above, synthetic lubricant better protects internal compressor parts. The parts experience less general wear when they are properly lubricated. They consequentially last much longer and users will need to replace machine parts less frequently. Regular scheduled maintenance should therefore be less invasive and less costly. Not to mentioned the savings by limited unexpected downtime.
Though synthetic options may appear more expensive at first glance. They often last much longer (4-6 times!) than traditional options. With longer operating hours, users will quickly see a return on their investment, and that doesn’t even include the energy savings benefits discussed above!
Choosing the right lubricant
Always refer first to known manufacturer recommendations when trying to decide between lubricant options. Manufacturers have a good understanding of the limitations and the needs of their equipment. Their recommendations come with a good deal of insight and thought. In fact, in some situations, going against manufacturer recommendations can actually prevent consumer protections, such as warranty claims. Be conscious of expectations and available options.
In the case of confusing recommendations, compressed air service specialists, like those at CASCO USA, can help determine exactly what your system needs. They have experience working with a variety of machines and products. They’ll be able to recommend the best option to keep your machine running efficiently, effectively, and smoothly.
