Why Choose a Vyking Force Oil Free Air Compressor over an oil compressor? 1st is Noise ProductionOne major difference between oil compressors and the Vyking Force oil-free compressors is in their noise production. The Vyking Force Oil-free compressors are up to 20% less noisy than oil units. The design of our compressor is more stable with fewer balancing issues than an oil compressor, therefore, producing less noise.2nd is Air ContaminationOne of the major issues that arise when using oil-lubricated air compressors is that the compressed air gets contaminated with oil. Depending on what you’re using the compressed air for, this can be very detrimental to the tools you’re powering with it and the projects you’re working on. Using oil-contaminated air with tools such as spray guns might contaminate the paint with oil, making it harder for the paint to dry or have a good finish. This is particularly important when painting a vehicle when you want the finish to be perfect. You can use oil traps and separators to remove the oil from the compressed air before passing it along to your tools and equipment, but if you really want no spec of oil in your system, using an oil-free unit is the way to go.3rd is MaintenanceJust like the oil in your car, the oil in the oil-lubricated unit will eventually go bad and will need replacement. That means you must remove it and replace it with new oil. You’ll need to carry on continuous routine maintenance when using a compressor with an oil-lubricated pump. On the other hand, the oil-free units come with permanent lubrication and does not need to be lubricated again throughout the life of the machine. That’s why they require less maintenance.
