Oil lubricated air compressors Oil-filled air compressors use oil as a lubricant for the cast iron of the pump. These compressors also generate enormous amounts of heat due to the high workload. The oil-air compressor can be more durable and functional. Therefore, it is suitable for industrial compressors. Lubricated with oil, it is less noisy than oil-free air compressors. Another advantage of oil lubrication is that it is less likely to wear. There are some drawbacks when using oil-lubricated air compressors. The device requires advanced maintenance. Regular efforts are made to change the lubricant now and then. Oil free air compressors The name “oil-free air compressor” speaks for itself. There is no need to add oil regularly to maintain lubricity.  But don’t assume that these compressors aren’t lubricated at all. They are. Also, the workload is much less than oiled lubricants, so there is no need to lubricate regularly. The product used as a lubricant for these compressors is called Teflon. It is less costly than the oil-air compressor. Most of these compressors are essential for remote use. Therefore, household and non-commercial purposes also serve them well. In addition to being lightweight and compact, oil-free compressors have some drawbacks from another perspective. They are more vulnerable to damage as they are more exposed to the weather without the previous coating. In addition, the useful life of the lubricant provided will decrease over time. As a result, internal components are prone to wear and damage. The noise level is much higher than an oil compressor, making it difficult to use at home. However, brands on the market today are wary of this issue and appear to be offering silencer versions of these models.
