Which Is Better: Oil or Oil-Free Air Compressors?
It depends on what you prefer. Oil-free compressors are easier to maintain and kinder to the environment because they don’t produce waste oil. However, oil compressors are better suited to heavy tasks.
Also, oil compressors last longer because they are continually lubricated. The downside with oil-based compressors is the upkeep and the cost of fresh oil.
